Which equation is equivalent to 2x+ 1.5 = 4.5
•2x+3=0
•x=3
•2x=6
•2x-3=0
Which of the following expressions is equivalent to 2x + y − 4y + 8?
Question 10 options:
A. 2x + 3y + 8
B. 3x − 4y + 8
C. 2x − 4y + 8
D. 2x − 3y + 8
Answer:
2x - 3y + 8
Step-by-step explanation:
If you combine like terms
(In this case "y" and "-4y")
You get "-3y"
The rest of the equation stays the same, as there are no more like terms.
Therefore the answer is the D.
Which equation can be used to find 150% of 500?
Pls ignore that I selected C.
Answer:
A?
Step-by-step explanation:
A is the only one that makes sense, becaues 150% of 500 is 750.
150/100 = 150%
5/5, I believe, just represents the 5 in 500.

Divide. Write the quotient in the lowest terms. 3/5 divided by 2 1/2
Answer:
6/25
Step-by-step explanation:
2 1/2 = 5/2
3/5 / 5/2 = 3/5 * 2/5 = 6/25
find the slope of the line
Answer:
Undefined
Step-by-step explanation:
The graph shows a vertical line. All vertical lines have a undefined slope.
This is because that while using the slope formula you will end of with the denominator being 0. You cannot divide by zero.

Tara has ¾ cup of ice cream. How many ⅕ cup servings are in ¾ cup of ice cream?
Answer:
3 3/4
Step-by-step explanation:
3/4 * 1/5
First you would turn 1/5 into a reciprocal
Now your equation would be 3/4 *5/1
Now you multiply 3/4 * 5/1
15/4
Now find 15/4 as a mixed number
15/4 as a mixed number would be 3 3/4
Therefore there are 3 3/4 1/2 cup servings in a 3/4 cup of ice
You are Gina versus the 40% of the students to apply. All the students in the University at six, 35% actually enroll. It's 10,000 students apply, how many actually enroll?
Answer:
1,400 students
Step-by-step explanation:
Calculation for how many actually enroll
First step is to calculate the numbers of students that was accepted
Numbers of students accepted=10,000 students*40%
Numbers of students accepted=4,000 students
Now let calculate the numbers of students that was enrolled
Students enrolled=4,000 students*35%
Students enrolled=1,400 students
Therefore the numbers of students that actually enrolled is 1,400 students

What is the solution to this system of equations? 2t + w = 10 4t = 20 − 2w A. It has no solution. B. It has infinite solutions. C. It has a single solution: t = 4, w = 2. D. It has a single solution: t = 2, w = 6. E. It has a single solution: t = 6, w = -2.
Answer:
B. It has infinite solutionsStep-by-step explanation:
Given the system of equations:
2t + w = 10 ..... 1
4t = 20 − 2w ... 2
From 1:
w = 10-2t ...3
Substitute 3 into 2 to have;
4t = 20 - 2(10-2t)
4t = 20-20+4t
4t = 4t
Let t = k
Substitute t = k into 1 and get w;
From 1: 2t + w = 10
2k + w =10
w = 10 - 2k
k can take any integers. This shows that the solution to the equation is infinite

Lin runs 2 3/4 miles in 2/5 of an hour. Tlyer runs 8 2/3 miles in 4/3 of an hour. How long does it take for each of them to run 10 miles
Answer:
Lin 1.454 h
Noah 1.54h
Step-by-step explanation:
From the above, we were given that;
Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour
Speed of Lin
V = [(2 3/4)/(2/5)] mph
V = [(11/4)/(2/5)] mph
V = 6.875mph
Speed of Noah
V = [(8 2/3)/(4/3)] mph
V = [26/3)/(4/3))] mph
V = 6.5mph
The time taken by Lin to cover 10 miles
t = 10/6.875
t = 1.454h
The time taken by Noah to cover 10 miles
t = 10/6.5
t = 1.54h

Step-by-step explanation:
Write 125 as a product of primes. Use index notation when giving your answer.
Answer:
5^3
Step-by-step explanation:
125= 5*25
25=5*5
5 is a prime number and there are 3 of them so the answer in index notation will be 5^3
Evaluate h(x) = -2x + 9 when x = -2.0. and 5
Answer:
h(-2) = 13
h(5) = -1
Step-by-step explanation:
Given the function
h(x) = -2x + 9
Evaluating at x = -22
substitute x = -2
h(-2) = -2(-2) + 9
h(-2) = 4 + 9
h(-2) = 13
Therefore,
h(-2) = 13Evaluating at x = 5
Given the function
h(x) = -2x + 9
substitute x = 5
h(5) = -2(5) + 9
h(5) = -10 + 9
h(5) = -1
Therefore,
h(5) = -1Find the slope of the line graphed below.
Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
~~~~~~~~~~~
(3, 3)
( - 2, - 3)
m = [tex]\frac{-3-3}{-2-3}[/tex] = [tex]\frac{6}{5}[/tex]

given f (x) = 3x+4, find f (2)
f(x) = 4x + 4 means that if we put an x into our function, a 3x + 4 come out.
So in this problem, we're putting a 2 into our function which
means that a 3(2) + 1 comes out which simplifies to 6 + 1 or 7.
So f(2) = 7 or the value of the function at 2 equals 7.
[tex]f(x) = 3x + 4[/tex]
Find f(2) by substituting x = 2 in the equation.[tex]f(2) = 3(2) + 4 \\ f(2) = 6 + 4 \\ f(2) = 10[/tex]
Therefore the value of f(2) is 10.
Meaning of f(a) and substitution in functionf(a) means the value of f(x) is ... at x = a. Same goes to the f(2) = 10. It means the value of f(x) = 10 at x = 2.
Answer[tex]f(2) = 10[/tex]

Fraction or decimal form round all the way!
Answer:
Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0
Step-by-step explanation:
We need to solve the expression: [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]
Solving the expression:
We will use simple maths rules to solve the expression
[tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]
Subtracting 1/2 on both sides and simplify
[tex]x+\frac{1}{2}-x-\frac{1}{2}=\frac{1}{2}-\frac{1}{2}\\x-x=0\\0=0[/tex]
Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0
So, the expression is true for all values of x. there will be infinite solutions to the system.
A mechanic makes $350 /week. If 20% of his income is deducted for taxes, how muchd id the mechanic bring home as pay?
Answer:
$280
Step-by-step explanation:
Step one
Given data
A mechanic makes $350 /week
20% of his income is deducted for taxes
Required
the mechanic's take-home pay for the week
Step two:
let us find 20% of $350
=20/100*350
= 0.2*350
=$70
Therefore the take-home pay is
= 350-70
= $280
In Jonesville Louisiana 125 students attend last Friday high school football game. This about 25% of the students currently enrolled at the school. How many students are enrolled at the high school?
Answer:
500 students
Step-by-step explanation:
In Jonesville Louisiana 125 students attend last Friday high school football game. This about 25% of the students currently enrolled at the school. How many students are enrolled at the high school?
Let the number of students enrolled at the high school be represented as x
Hence:
25% of x = 125
25/100 × x = 125
25x /100 = 125
Cross Multiply
25x = 125 × 100
x = 125× 100/25
x = 500 students
