/ -10 / -10
c = -2
-2(4r - 6) Mathhhhhhhhh pls
Answer: -8r+12
Step-by-step explanation:
============================================
Explanation:
The outer term -2 is multiplied by each term inside
-2 times 4r = -8r-2 times -6 = 12Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.
I used the distribution property, also known as the distributive property.
That says a*(b-c) = a*b - a*c
In this case, a = -2, b = 4r, and c = 6.

The Claxtons drove 150 miles in 3 hours and they are continuing to drive at the same rate. Which statements are true? Mark all that apply
a
it will take them 5 hours to drive 200 miles
b

c
it will take them 14 hours to drive 600 miles
d
It will take them 18 hours to drive 900 miles
e
It will take them 1 hour to drive 50 miles
Answer: To convert the time it takes to travel a certain number of hours, you need to know your ... how many hours it takes to drive a certain number of miles, and you can also ... If you're traveling in a line from point A to point B, determining your average ... often use the words speed and velocity interchangeably, they aren't the same!
Step-by-step explanation:
Answer:
B. it will take them 8 hours to drive 400 miles
D. It will take them 18 hours to drive 900 miles
E. It will take them 1 hour to drive 50 miles
Step-by-step explanation:
First, you solve for how fast there going an hour so in three hours they go 150 so we can divide 150 by 3 and we get 50. That means they go 50 miles in an hour. Then we can multiply 50 by the hours and see if we get the same number on miles.
The original price of a scarf was $16. During a store-closing sale, a shopper saved $12 on the scarf. What percentage discount did she receive? Explain or show your reasoning.
Answer:
She received 75% discount on the price of scarf
Step-by-step explanation:
The price of the scarf was 16, 16 is 100%.
The shopper saved 12 dollars on the scarf so he
bought it for 4 dollars. So 12×100/16 = 75%
−15x−40=23−8x
What does x =
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
Add 8x to both sides
-15x + 8x - 40 = 23
-7x - 40 = 23
Add 40 to both sides
- 7x = 23 + 40
-7x = 63
Divide both sides by (-7)
x = 63/-7
x = -9
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
add 8x to both sides to bring -8x to the left side
-15x + 8x - 40 = 23
add 40 to both sides to bring -40 to the right side
-15x + 8x = 23 + 40
add the common terms
-7x = 63
for x to be alone divide -7 to both sides
x = -9

solve the system of equations using elimination.
X-Y=3
2x+2y=50
Answer:
abcdefg
Step-by-step explanation:
Answer:
x = 14
y = 11
Step-by-step explanation:
x - y = 3
2x + 2y = 50
multiplty x - y = 3 by two so we can get an equal value
2x - 2y = 6
2x + 2y = 50
-2y and 2y can be cancled out. That means we don't need to change any signs and we can add everything exept 2y and -2y becuase they will be cancled out.
4x = 56
Divide each side by 4 to leave x alone.
x = 14
Now that we know the x value, take one of the equations in the question and plug it in. I am going to use the equation x - y = 3 to make it easier.
14 - y = 3
-y = 3 - 14
-y = -11
y = 11
Now we know that y = 11.

Tristan is selling plastic and wooden picture frames. He sells 7 frames total. The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames. How many of each type of frame does Tristan sell?
Answer:
4 wooden and 3 plastic
Step-by-step explanation:
4 (wooden) × 2 - 5 = 3 plastic
3 (plastic) + 4 (wooden) = 7 total
The number of plastic frames is 4 and the number of wooden frames is 3.
What is equation?
A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given statement:
The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.
The total number of frames sold by Tristan is 7.
Write the equation for the above statement,
p = 2w - 5
Here, p is a plastic frame and w is a wooden frame,
p + w = 7
Solve the equation by using the elimination method,
p = 4 and w = 3
Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.

Step-by-step explanation:
Explain how you can find the volume of the figure below. Then, solve- what is the volume of the figure? Make sure to include your units
Answer: a) The figure can be reasonably divided into two geometries:
• a rectangular prism
• a hemisphere.
b) The volume of the rectangular prism is given by
V = lwh
V = (10 cm)(5 cm)(4 cm) = 200 cm³
The volume of the hemisphere is given by
V = (2π/3)r³
V = (2π/3)(3 cm)³ = 18π cm³
c) The total volume of the figure is
total volume = (prism volume) + (hemisphere volume)
V = 200 cm³ + 18π cm³
V ≈ 256.549 cm³
