Answer:
Pizzas are $15
Sandwiches are $8
Step-by-step explanation:
Write a system of equations
Pizza = x
Sandwiches = y
2x + 4y = 62
4x + 10y = 140
Isolate a variable in one of the equations
2x = 62 - 4y
x = 31 - 2y
Plug isolated x value into other equation
4(31-2y) +10y = 140
124 - 8y + 10y = 140
Simplify
2y = 16
y = 8
Plug y value into equation to solve for x
2x + 4(8) = 62
2x + 32 = 62
2x = 30
x = 15

Notice it is the same with the the first function
Thus, they are the same function, so they intersect each other infinitely many.
9 times what number equals 800?
Answer:
9 times 800/9 equals 800. (Answer is 800/9)
Step-by-step explanation:
Key skills needed: Equation, Division, Fractions
1) Let's say the number is the variable "x".
2) So this means 9 times x = 800
9x = 800
3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9
Hope you understood and have a nice day!! :D
88.8888888889
The equation to any of these sorts of questions is the larger number (800) divided by the smaller number (9).
You can check your answer by multiplying the quotient by the smaller number (9). If you get the larger number (800), you were correct, anything else, the equation was done wrong.

m + 4 = 17
Please help
Answer: m=13
Step-by-step explanation:
Basically you solve this by finding out what plus 4 equals 17. You can do this by subtracting 4 from 17.
17-4=13
This is how you find the value of m.
Answer:
13!
Step-by-step explanation:
first subtract 4 on both sides!
m+4=17
m+4-4=17-4
simplify/subtract 17-4=13!

What is the greatest common factor of 15 and 21?
The Greatest Common Factor of 15 and 21 is 3.
What is Greatest Common Factor?The greatest common factor is the largest number that is a factor of two or more numbers (GCF). The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both. The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the Highest Common Factor (HCF)
Given:
We have to find the greatest common factor of 15 and 21 .
So factorizing each number
15 = 3 x 5
21 = 3 x 7
So, the Greatest Common Factor is 3.

What is the equation of the line that passes through the point (1,3) and has a slope
of -- 32
Answer:
The equation of the line that passes through the point (1,3) and has a slope of -32.
[tex]y=-32x+35[/tex]
Please check the attached graph too.
Step-by-step explanation:
Given
Point (1, 3) The slope m = -32The point-slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line (x₁, y₁) is the pointIn our case:
m = -32
(x₁, y₁) = (1, 3)
substituting m = -32 and (x₁, y₁) = (1, 3) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-3=-32\left(x-1\right)[/tex]
Add 3 to both sides
[tex]y-3+3=-32\left(x-1\right)+3[/tex]
Simplify
[tex]y=-32x+35[/tex]
Therefore, the equation of the line that passes through the point (1,3) and has a slope of -32.
[tex]y=-32x+35[/tex]
Please check the attached graph too.

Abram and Fred leave opposite ends of a bike trail 8.5 miles apart and travel toward each other. Abram is traveling faster than Fred. Find each of their speeds if they meet after 30 minutes.
Complete question :
Abram and Fred leave opposite ends of a bike trail 8.5 miles apart and travel toward each other. Abram is traveling 3mph faster than Fred. Find each of their speeds if they meet after 30 minutes.
Answer:
Fred's speed = 7mph
Abrams speed = 7 + 3 = 10 mph
Step-by-step explanation:
Given that :
Distance apart = 8.5 miles
Let :
Fred's speed = x
Abram's speed = x + 3
Time they meet = 30 minutes = 0.5 hour
Speed = distance / time
Distance = speed * time.
Fred's distance + Abram's distance = 8.5 miles
(x * 0.5) + (x + 3)*0.5 = 8.5
0.5x + 0.5x + 1.5 = 8.5
x + 1.5 = 8.5
x = 8.5 - 1.5
x = 7 mph
Fred's speed = 7mph
Abrams speed = 7 + 3 = 10 mph

A school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping. How much did they make selling balloons?
Answer:
OMG, Nickkkkk. It's Nyla from your 3rd block math classs. Lol, I literally looked up this question with no luck of an answer.
Step-by-step explanation:
The school club made $298.08 by selling the balloons.
What is Profit?Profit is calculated as total revenue less total expenses.
Given that, a school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping.
Cost of balloons when they brought them = 1.29*150 = $193.5
Total cost = $193.5 + (shipping price) = $193.5 + $8.92
Total cost = $202.42
Cost at which they sold the balloons = 143*$3.50 = $500.5
Therefore, their total profit = $500.5 - $202.42 = $298.08
Hence, The school club made $298.08 by selling the balloons

Which expression is equivalent to 4t + 3t
Answer:
C
Step-by-step explanation:
i think
Answer:
C. 7t
Step-by-step explanation:
What we know:
We are looking for an expression equal to 4t + 3t.
There are 4 choices:
1. 7t²
2. 7 + 2t
3. 7t
4. 12t
The answer does end in t, but is only one term, so B is eliminated.
An exponent is not involved either, so A is also eliminated.
It shows an addition sign, not multiplication, so D is also out.
This leaves C, which is 7t.
Doing this mathematically, add like terms.
4t + 3t
7t

Answer:
scale factor: 3
Step-by-step explanation:
For this I will take both A and A' points. So A is (2,2) and A' is (6,6) and since the shape increased in size that means our scale factor must be greater than 1. So all that we have to do is know is how did we get from this x value to that x value or in other words 2 times what equals 6 and it's 3. Then we would do the same for the y value but since it would be the same 2 times what equals 6 and it's still 3 so 3 is the scale factor.
A triangle has side lengths of ( 5.9 k + 9.3 m ) (5.9k+9.3m) centimeters, ( 3.6 k − 3.9 n ) (3.6k−3.9n) centimeters, and ( 3.5 n + 3.4 m ) (3.5n+3.4m) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
(9.5k + 12.7m -0.4n) cm
Step-by-step explanation:
(5.9k+9.3m) + (3.6k−3.9n) + (3.5n+3.4m) = 9.5k + 12.7m -0.4n
