Answer:
A. $0.25 per ounce
B. 4 ounces per dollar
Step-by-step explanation:
As you want. She bought 10 ounces of spicy popcorn for $2.50. When writing your answer write it as a whole number or a decimal.
A) How much does popcorn cost per ounce? The cost per ounce is dollars.
10 ounces of spicy popcorn = $2.50
1 ounce of spicy popcorn = x
Cross Multiply
10 ounces × x = $2.50
x = $2.50/10 ounces
x = $0.25 per ounce
B) How much popcorn can you buy per dollar? You can buy ounces of popcorn per dollar.
$2.50 = 10 ounces of spicy popcorn
$1 = x ounce of spicy popcorn
Cross Multiply
$2.50 × x = 10
x = 10/2.50
x = 4 ounces per dollar
C) Write two different equations that represent this situation. Use pp for ounces of popcorn and cc for cost in dollars. The first equation is and the second equation is

If a term doesn't have a coefficient , it is considered that the coefficient is 1
[tex]2x+1x-4y[/tex]
Why is it considered that the coefficient is 1?
Remember that any term multiplied by 1 remains the same:
[tex]1.x=x[/tex]
Step 1
The equality can be read in the other way as well , so any term can be written as a product of 1 and itself:
[tex]x=1 . X \\[/tex]
Step 2
Usually, we don't need to write multiplication sign between the coefficient and the variable , so the simpler form is:
[tex]x=1x[/tex]
That is why we can write the term without the coefficient as a term with coefficient 1.
Let's go back to your problem now

The formula a subscript n = 10 - 4n describes an arithmetic sequence. What are the first four
terms in the sequence?
A)6, 2, -2,-6
B) 6,2,0,-2
C)10, 6, 2,-2
D)14, 18, 22, 26
Answer:
A)6, 2, -2,-6
Step-by-step explanation:
a(n) = a +(n-1)d
a(n) = a +dn-d
a(n) = a-d + dn
a(n) = 10 - 4n
So d=-4
to get a: (a-d)=10
a=10-4=6
The first four terms:
a(1) = 6 +(1-1)-4=6
a(2) = 6 +(2-1)-4=2
a(3) = 6 +(3-1)-4=-2
a(4) = 6 +(4-1)-4=-6
it will be A

A recipe uses 1/3 cup of flour and 1/8 cup of sugar.How much flour and sugar does the recipe use altogether?
Answer:
11/24
Step-by-step explanation:
Just add 1/3 and 1/8 to get the answer. To add or subtract any pair of fractions they must have the same denominator. To change them, find the least common multiple of the two denominators (3 and 8). The least common multiple of 3 and 8 is 24. Now multiply the denominator by a number that’ll make it into the least common multiple. The 3 in 1/3 should be multiplied by 8 to make it into 24. The 8 in 1/8 should be multiplied by 3 to make into 24. The number that you use to multiply each denominator should also be used to multiply the numerator of that fraction. 1/3 for example, becomes 8/24. 1/8 becomes 3/24. Finally add the numerators of both numbers and keep the same denominator which equals 11/24.

Step-by-step explanation:
Number 1) Don’t get confused with the -10 and 10, we already know that the value is already 20 so that narrows it to 2 choices. Now everytime you move on, it subtracts 10 so its 20:-10
Number 2) This one is pretty easy, we know that he drives about 12,000 miles a year but we don’t know how many years, so that unknown variable would be (x), now the 40,000 miles was already on it so that can’t change, only The years change so therefore the equation could be 12,000x+40,000
You have $20 to spend at the dollar store for Jake and Julian's birthdays. You want to buy 2 sodas for Jake, 4 candy bars for Julian, and an equal number of balloons b for them both with the rest of your money. Which equation below will determine how many balloons each friend receives?
Answers
2+4+b/2 =20
2+4+b =20
2+4+2b =20
20-4-2 =b
2(2+4+b) =20
Using a system of equations, the equation that determines how many balloons each friend receives is given by:
2 + 4 + 2b = 20.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable s: number of sodas bought.Variable c: number of candy bars bought.Variable b: number of balloons bought.You want to buy 2 sodas for Jake, 4 candy bars for Julian, hence:
s = 2, c = 4.
An equal number of balloons b, hence 2b is added to the equation, as the amount has to be 2, 4, 6, and so on, considering one balloon for each.
The total amount of money is of $20, hence the equation is:
2 + 4 + 2b = 20.

The equation of line is given as : y = 3x + 6
According to the question we have been given that the line passes through the points (-1,3) and has gradient 3
We need to find the equation of line. The general form of slope intercept form is
y = mx + c
where, m = slope

10. A washing machine repairer charges a total of £T for a repair which takes H hours. The formula
connecting T and H is
T = 35 + 20H.
Find H when T is 85.
The value of H when T is 85 is 2.5 hours which is calculated from the linear equation in two variables.
The linear equation in two variables is defined as an equation which defines the relationship between two unknown variables.
The general form of linear equation is of the form ax + by = c where a and b are constant co-efficient and c is a constant. Here y is the dependent variable and x is the independent variable.The graph of a linear equation in two variables is a straight line in the cartesian plane.Given the linear equation for total amount of money(T) which is the dependent variable using the independent variable H(number of hours worked) .
T=35 + 20 H
At T = 85 , we substitute the value of T in the linear equation to find H .
T=35 + 20 H
or, 85 = 35 + 20H
or, 50=20H
or, H=2.5
Therefore the value of H is 2.5 hours when T is 85.

How do you get from one number to the next using multiplication or division?
From 100 to 106.
We can move from 100 to 10^6 by multiplying with 10^4.
How do you use multiplication?We know that it is possible to move from one value to another by the use of multiplication or division. Now in either case, there is a value that we have to us to multiply or divide another number order to move from one number to another.
Now we have the number 100 and we want to change it to 10^6. The implication of this is that the number 100 must have to be multiplied by the number 10^4 in order to arrive at the expected destination.

Answer:
The archaeologists dis not actually discovered the lost temple
Step-by-step explanation:
For us to be able to determine if the archaeologist actually discovered the lost temple, we need to find the dimension of the temple first.
Area of the temple = LW
Perimeter = 2L + 2W
L is the length
W is the width
If the perimeter is 220m
220 = 2L + 2W
110 = L+W ... 1
If the area is 2100 square meters
A = LW
2100 = LW ... 2
From 1;
L = 110 - W .... 3
Substitute 3 into 2
From 2;
2100 = LW
2100 = (110-W)W
2100 = 110W - W²
- W² + 110W - 2100 = 0
W² - 110W + 2100 = 0
Using the general formula;
W = -(-110)±√(-110)²-4(1)(2100)/2
W = 110±√3700/2
W = 110±60.83/2
W = 110±60.83/2
W = 110+60.83/2 and W = 110-60.83/2
W = 170.83/2 and 49.17/2
W = 85.415m and 24.585m
Substitute the width into the formula to get the length;
LW = 2100
L = 2100/W
L = 2100/85.415
L = 24.59 m
If the width is 24.585m;
L = 2100/24.585
L = 85.42m
Since we have different dimension of the temple, this show shat the archaeologists dis not actually discovered the lost temple
