7x-(x-y) = 7x - x + y = 6x + y
9a-(2b-a) = 9a+a-2b = 10a-2b

Answer:
The perimeter of the un-shaded portion is 42 cm
Step-by-step explanation:
The given information are;
The diameter of the circle = 7 cm
The perimeter of the entire figure = 42 cm.
The formula for the perimeter = 2 semi circles + 2 Side lengths, l
The formula for the perimeter = 2 × π·D/2 + 2× l
42 = 2×π·7/2 + 2·l = π·7 + 2·l
2·l = 42 - π×7 = 20.009 cm
l = 20.009 cm/2 = 10.004 cm
The perimeter of the un-shaded portion, = 2 side length + 2 semicircles
∴ = 2×l + 2 × π·D/2 = 2×l + 2×π·7/2 = 2·l + π·7 = 2×10.004 + π×7
= 41.999 ≈ 42 cm
Therefore, the perimeter of the un-shaded portion = 42 cm.
R = recycling and reuse industry jobs
w = waste management jobs
we know, those two jobs combined are 1,275,000
or
r + w = 1,275,000
we also know that, whatever the "w" jobs are, are really less than "r"
jobs by 1,025,000
"r" has 1,025,000 more than "w"
or
r = w + 1,025,000
or
r-w = 1,025,000
so... there, just solve by elimination, simple, notice the "w",
is just waiting to be eliminated :)
Answer:
y intercept is 13
Step-by-step explanation:
y - 3 = 2(x + 5)
To find the y intercept, let x=0 and solve for y
y - 3 = 2(0 + 5)
y - 3 = 2(5)
y -3 =10
y-3+3 = 10+3
y = 13
