- ------ + ------ <-------- Fraction bar

1. Get both fractions to have the same denominator which is 24 because it is the Least Common Multiple (LCM) - 1st fraction multiply by 3 on numerator and denominator, 2nd fraction multiply by 4 on numerator and denominator.
9 52
- ------ + ----- <-------- Fraction bar
24 24
2. Subtract the two fractions - there is a negative number and positive number, so we need to subtract even though it is addition because they are different signs. The answer is positive because it is the bigger number.
43
= ------ <-------- Fraction bar
24
3. The answer is already simplified because there are no common factors for 43 and 24. So the final answer is ...

at sue birdwell intermediate school the ratio of boys to girls is 7 to 5. if there are 150 girls at school, how many boys are at the school
Answer:
210 boys
Step-by-step explanation:
the ratio is 7 boys to 5 girls. There are 150 girls at the school. Divide 150 by 5 to get your answer which is 30. We know that we have to divide because the ratio answer is a simplified version of 150, like if we were doing fractions. Then multiply 30 times 7 and you will get 210. So there are 210 boys at the school.

Bernice estimated that 69% of 242 is 168. Is her estimate reasonable?
No, because her calculation should be 60% of 250.
No, because her calculation should be 70% of 250.
Yes, because her calculation should be 60% of 240.
Yes, because her calculation should be 70% of 240.
Answer:
Yes, because her calculation should be 70% of 240.
Step-by-step explanation:
69% can be estimated to 70% and
242 can be rounded off to 240.
70% of 240 = 0.7 * 240
= 168

Assuming all parabolas are of the form y=ax^2+bx+c, drag and drop the graphs to match the appropriate a-value
9514 1404 393
Answer:
graphs left to right have a=1, a=0.25, a=-1
Step-by-step explanation:
A negative value of 'a' makes the parabola open downward, so the rightmost graph goes with a=-1.
A value of 'a' less than 1 flattens the graph, so the middle graph goes with a=0.25.
A value of 1 gives a standard open-upward parabola, corresponding to the leftmost graph.

The store is selling lemons at $0.66 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make three 9-inch lemon pies,each requiring half a cup of lemon juice
Answer:
It will cost $7.92
Step-by-step explanation:
We will need to find out how many table spoons of lemon we will need first.
We need to make 3 pies requiring half a cup of lemon juice.
3 * 1/2 = 1.5 cups
We convert the cups to tablespoons
1.5 * 16 = 24 tablespoons
Then, since each lemon yields two tablespoons, we divide the tablespoons required by two. This is to find the number of lemons we need.
24/2 = 12
We multiply lemons by the price the store is selling them.
12 * $0.66 = $7.92
This is the price to buy enough lemons to make the 9-inch lemon pies.

. What are the coordinates of the other endpoint?
The co-ordinates of D is if the midpoint E is at (-1,0 )which is calculated using the section formula.
In coordinate geometry, the Section formula is used to determine the internal or external ratio at which a line segment is divided by a point. It is used to determine a triangle's centroid, incenter, and excentre.
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
The section formula is given by:
[tex]{\displaystyle P=\left({\frac {mx_{2}+nx_{1}}{m+n}},{\frac {my_{2}+ny_{1}}{m+n}}\right)}[/tex]
where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.
The midpoint is calculated by:
[tex]{\displaystyle Q=\left({\dfrac {x_{1}+x_{2}}{2}},{\dfrac {y_{1}+y_{2}}{2}}\right)}[/tex]
where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.
Now the given co-ordinates of the points are C(5, 2) and the midpoint is E(-1 , 0). Now to find the co-ordinates of D we have to use the midpoint formula.
Let the co-ordinate's of D be (a , b) then by using the above midpoint formula we get:
-1 = (5+a) ÷ 2
or, a = -2 -5
or, a = -7
again
0 = (2+b) ÷ 2
or, b = -2
Hence the co-ordinates of D is (-7 , -2)

Colton works at an electronics store as a salesperson. Colton earns a 7% commission on the total dollar amount of all phone sales he makes, and earns a 3% commission on all computer sales. Colton had twice as much in phone sales as he had in computer sales and earned a total of $85 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Colton made and the dollar amount of computer sales he made. Define the variables that you use to write the system.
The equations that could be used to determine the dollar amount of phone sales will be:
0.07x + 0.03y = 85
y = 2x
How to illustrate the information?Let x represent the total dollar amount of the phone sales she makes.
Let y represent the total dollar amount of the computer sales she makes.
Colton earns a 10% commission on the total dollar amount of all phone sales she makes, and earns a 4% commission on all computer sales. If she earned a total of $162 in commission, it means that
0.07x + 0.03y = 85
She had twice as much in computer sales as she had in phone sales. This means that y = 2x.

Describe the domain and range.
1. r(x) = | |x|
Domain of r(x) = |x| is ( −∞, ∞ ) , { x | x ∈ R }
Range of r(x) = |x| is [ 0 , ∞ ) , { y | y ≥ 0 }
The domain of a function is defined as the set of values that we are allowed to enter into the function. This set is a bunch of x values in a function such as r(x).
The domain of the given function r(x) is all real numbers except where this expression, r(x) = |x| is undefined. In this question, there is no real number that makes this expression undefined.
The interval is denoted as ( −∞ , ∞ ).
The set builder is denoted as { x | x ∈ R }.
The range of a function is defined as the set of values that the function can assume. This set is a bunch of the values that the function shoots out after we enter a x value in. The range is a set of all valid y values. We have to use the graph to find the range.
The interval is denoted as [ 0 , ∞ )
The set builder is denoted as { y | y ≥ 0 }
Therefore, we get the domain and range as,
Domain of r(x) = |x| is ( −∞, ∞ ) , { x | x ∈ R }
Range of r(x) = |x| is [ 0 , ∞ ) , { y | y ≥ 0 }

Complete question is;
Elle Measured the height of a plant, in inches,Every week for four weeks after planting it.
The height of the plant, h, in inches, Can be modeled by the function h(t) = 1.5t + 3, where t represents the time in weeks.
Based on this model, what is the best prediction for the height of the plant after 12 weeks?
A 16.5 inches
B 21 inches
C 22.5 inches
D 27.3 inches
Answer:
Option B: 21 inches
Step-by-step explanation:
We are given the function h(t) = 1.5t + 3, where t represents the time in weeks.
At t = 0;
h(0): 1.5(0) + 3 = 3inches
At t = 1;
h(1): 1.5(1) + 3 = 4.5 inches
Thus, after 12 weeks, height will be;
h(12): 1.5(12) + 3 = 21 inches
Option B is correct

Find the circumference of the circle use 3.14 for
Pi Round to the nearest hundred put the answer in cm
Need ASAP if u don’t know the answer don’t answer
Answer:
47.1 cm
Step-by-step explanation:
The circumference of a circle is denoted by C = 2πr, where r is the radius.
Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:
C = 2πr
C = 2 * 3.14 * 7.5 = 47.1
To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.
Thus, the circumference is 47.1 cm.
The value of x for which 3 (x-2) = 2 (x+1)
Answer:
x = 8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
3(x - 2) = 2(x + 1)
Step 2: Solve for x
Distribute: 3x - 6 = 2x + 2Subtract 2x on both sides: x - 6 = 2Add 6 to both sides: x = 8Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(8 - 2) = 2(8 + 1)Subtract/Add: 3(6) = 2(9)Multiply: 18 = 18Here we see that 18 does indeed equal 18.
∴ x = 8 is a solution to the equation.
