Answer:
Step-by-step explanation:
In order to combine like terms, you have to isolate x and y from one side of the equation.

<u>First, thing you do is remove parentheses.</u>

<u>Solve.</u>
<u>Then, you combine like terms.</u>

<u>Add/subtract the numbers from left to right.</u>
-8z+3.5z=-4.5z
<u>Rewrite the problem down.</u>

<u>Solve.</u>
4.5-1.5=3

- <u>Therefore, the correct answer is 7y+3-4.5z.</u>

Answer:
P = 14 * 22.5/5 = 63
Step-by-step explanation:
Step1. Find perimeter of small triangle
Step2. Find the ratio between 2 triangles
Step3. Multiply
The three angles of a triangle should equal 180 so add 52+34 which equals 86.Then subtract 86 from 180 to get the third angles measure which is 94 so the answer is 94.

To round to the nearest tenth, you need know whether the number next to tenth place is greater than 5 or lesser than 5. If its greater than 5, you need to round up. If its lesser than 5, you need to round down. Now, in the number 26.99 9 is in the tenth place. The number next to 9 is greater than 5, so just add on to the ones place, making the tenth and hundredth place 0. Zero has no value so whether you add the zero or not, it does not matter.

Answer:
you have a fixed rate of $25, meaning you get a haircut, it's $25
ANY other service is an extra $15
So, let's make the equation...
y=15x+25
Now, to just get a haircut it's $25.
But, let's say you get a haircut+shampoo
It'd be..
y=15(1)+25
y=$40
Another one..
You get a haircut+shampoo+highlight
y=15(3)+25
y=$70
