The answer is b 20
because the ratio of both is 1:2
and then x =10 then z=20
brainliest and follow please
5a+3b = 24
(5+a)(3+b) = 49
The order of steps are different because one requires multiplication then addition while the other one requires addition then multiplication. But one sure thing is that they both need substitution.
The perimeter would also be 18 square feet
Answer:
for #1 it's 1, 4, 5, 6
for #2 it's both lines have the same slope
for #3 it's both lines have a different y-intercept
Step-by-step explanation:
#1 explanation: all of them have the y-intercept of -8
ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)
#2 explanation: both have a slope of (1/4)
#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different
