Answer:
x = -24/7
Step-by-step explanation:
To solve, you need to multiply both sides by 10 ( the GCF of 5 and 2) to get rid of the fractions. Once multiplied, you get this:
2(4x-2) + 5(1) = 5(3x+7) - 10(1)
Now, just distribute the parenthesis:
8x - 4 + 5 = 15x + 35 - 10
Now, combine like terms:
8x + 1 = 15x + 25
15x + 25 = 8x + 1 (rearranged the equation)
Subtract the x's:
7x + 25 = 1
Now solve:
7x = -24
x = -24/7
Answer:
see explanation
Step-by-step explanation:
Calculate the perimeters by summing the measures of the sides.
Left figure ( starting with base and summing clockwise )
x + 5 + (x - 6) + (y - 5) + 6 + y ( brackets are the measure of the indents )
= x + 5 + x - 6 + y - 5 + 6 + y
= 2x + 2y
Right figure ( starting with base and summing clockwise )
x + 2 + (x - 3) + (y - 2) + 3 + y
= x + 2 + x - 3 + y - 2 + 3 + y
= 2x + 2y
Both figures have perimeters of 2x + 2y cm
