Answer:
x = 59
Step-by-step explanation:
since the quadrilateral add up to 360 degrees,
X + X + (2x + 3 ) + (2x + 3) would equal 360 degrees
x + x + (2x + 3) + (2x + 3) = 360
6x + 6 = 360, addtion
6x = 354, subtraction
x = 59, division
10x-5
f(x)=5x
g(x)=2x-1
To create a composite function, replace x in f(x) with g(x)
f(g(x)) = 5(g(x) = 5(2x-1) = 10x-5
1/3 (3y - 6) = 8
distribute: y - 2 = 8
add 2 to both sides: y = 10

567 miles
we break down how many miles he went in 1 hour
315/5
he went 63 miles in 1 hour
times this by 9 is 567 miles in 9 hours
