Answer:
x=22
Step-by-step explanation:
To find the x value, you need to use reverse PEMDAS (or GEMDAS as I've seen some people call it)
First, you subtract 4 from both sides of the equation. This should give you:
1/2x=11
Then, you divide 1/2 on each side. Although it's easier to multiply 2 on each side instead. This will give you.
x=22
You could have half a cookie, divide it into thirds. (a semi circle cut into thirds)
Answer:
12.5x+10
Step-by-step explanation:
I'm assuming that you want to simplify this, because there is no equal sign.
If you want to simplify, first combine like terms.
First solve the first half of the equation: 20x-7.5x=12.5x
Now solve the second half of the equation: 12-2=10, so we have 12.5x+10.
That's your answer: 12.5x+10
Answer:
It i 5.Because it is Equlitrial triangle
Answer:
length = 10 ft, width = 9 ft
Step-by-step explanation:
The opposite sides are congruent
The perimeter (P) = 38 and is the sum of the 4 sides, then
15 - 2x + 15 - 2x + x + 7 + x + 7 = 38 , that is
- 2x + 44 = 38 ( subtract 44 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3
Then
length = x + 7 = 3 + 7 = 10 ft
width = 15 - 2x = 15 - 2(3) = 15 - 6 = 9 ft
