Billy and Tommy went to the movies. They are going to combine their money for snacks. Popcorn costs $8 and a box of candy costs $1.50 each. They each want their own popcorn. They spent the rest of the money on candy. If the total cost was $25.00, how many boxes of candy did they buy? Create a algebraic equation and solve for the number of candy boxes.
Answer:
6 candy boxes
Step-by-step explanation:
Since they both bought their own popcorn that means they both spent $8 on popcorn making that a total of $16. Therefore we now only need to find one variable which is the number of candy boxes that they bought in order to reach the $25 total that they spent. This variable can be represented as x in the following algebraic equation.
(2*8) + 1.50x = 25
16 + 1.50x = 25 ... subtract 16 from both sides
1.50x = 9 ... divide both sides by 1.50
x = 6
Finally, we can see that Billy and Tommy bought a total of 6 candy boxes.

Anna is given the equation 5 + 3x = 3x + 5
The replacement set is {1, 2, 3, 4}
Anna says the solution is {2}, but the teacher marked her problem incorrect. Explain what the answer should be and why. Why do you think this is?
Answer:
There are infinite possibilities for x
Step-by-step explanation:
5 + 3x = 3x + 5
-5 -5
3x = 3x
÷3 ÷3
x = x
Therefore, you can put any replacement to x, and the equation would be true.

If A=1/2 h (b1 +b2) is the formula for the area of a trapezoid, find the height of the trapezoid that has an area of 78 in ^2 and base lengths 5 in and 8 in.
Answer:
A is the answer
12 in
first substitute the variables
then 78=1/2h(5 + 8)
this makes it an equation
add similar terms which equals to
78=1/2xhx13
then divide both sides by 13
6=1/2xh
lastly divide both sides by 1/2
12=h
Step-by-step explanation:
proof
A=1/2x12(5 + 8) then
A=1/2x12x13 then
A=6x13 then
A= 78in^2

Answer:
[tex]\boxed {m = -6}[/tex]
Step-by-step explanation:
Use the Slope Formula to help you determine the slope of the following two points:
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
(Where [tex](x_{1}, y_{1})[/tex] is the first point and [tex](x_{2}, y_{2})[/tex] is the second point)
-Apply both points onto that formula:
[tex](x_{1}, y_{1}) = (1, 1)[/tex]
[tex](x_{2}, y_{2}) = (0, 7)[/tex]
[tex]m = \frac{7 - 1}{0 - 1}[/tex]
-Solve:
[tex]m = \frac{7 - 1}{0 - 1}[/tex]
[tex]m = \frac{6}{-1}[/tex]
[tex]\boxed {m = -6}[/tex]

Haley got a 93% on her first math test and an 86% on her second test. What is her percent decrease from Test 1 to Test 2 to the nearest tenth?
Enter the correct answer in the box.
Answer:
7.5?
Step-by-step explanation:
Guessing!!! hope it's correct,
Because
Percent Decrease = Percentage Decrease=Starting Value−Final Value|Starting Value|×100
If Haley got a 93% on her first math test and an 86% on her second test. Her percent decrease from Test 1 to Test 2 to the nearest tenth will be 7.5%
Using this formula
Percentage Decrease=Starting percentage−Final percentage÷ Starting percentage×100
Where:
Starting percentage=93%
Final percentage=86%
Let plug in the formula
Percentage Decrease=93%-86%÷93%×100
Percentage Decrease=7%÷86%×100
Percentage Decrease=7.5%
Inconclusion if Haley got a 93% on her first math test and an 86% on her second test. Her percent decrease from Test 1 to Test 2 to the nearest tenth will be 7.5%

L is y=3x-2
L*2 is 3y-9x+5=0
Answer:
If two lines are parallel, then they have the same gradient.
Step-by-step explanation:
L is y=3x-2
L*2 is 3y-9x+5=0
The gradient for the first equation is 3
We need to rearrange the second equation and see if it has the same gradient as the first equation.
L*2 is 3y-9x+5=0
3y = 9x - 5
L*2 y = 3x - 5/3
As you can see, once you rearrange and simplify the equation, the second line has the same gradient as the first equation.
So that means these two lines are parallel
The larger of two numbers is twelve more than the twice smaller number. The sum of the numbers is 42. Find the two numbers . Please set up a , set up the equation , and then solve the equation .
Answer:
The smaller number: a = 10
The larger number is 32
Step-by-step explanation:
a - the smaller number
2a - twice the smaller number
2a+12 - twelve more than the twice smaller number (the larger number)
a + 2a+12 - the sum of the numbers
a + 2a+12 = 42
-12 -12
3a = 30
÷3 ÷3
a = 10
2a+12 = 2×10+12 = 20+12 = 32
Check: 10+32=42

Describe the process you used to find the equation of a line through two
points. Have you learned any tricks or shortcuts when doing this? Explain
if you have.
Answer:
Explanation at the bottom
Step-by-step explanation:
To find the slope with the 2 points use this ---> [tex]\frac{y2 - y1}{x2 - x1}[/tex] Ex: Points (9, 3) (6, 12) --> write it this way [tex]\frac{12 - 3}{6 - 9}[/tex] = [tex]\frac{9}{-3}[/tex] = -3 so -3 would be the slope of that line.
Then to find the y- intercept use the slope and the numbers from one of the points like this ----> y = mx + b we are looking for b.
(plugging in the first point) (using the point (9,3))
3 = -3(9) + b
3 = -27 + b (add 27 on both sides)
30 = b (that's your y- intercept)
(Full equation is)
y = -3x + 30
