I would say the best estimate would be 9 because the real answer is 8.71 and if you round that to the 1 place the answer would be 9.
False. If x=-3 and y=-6 and you substitute them into the equation they do not add up
Answer:
Shorter piece length is 18 inches
Step-by-step explanation:
Let's marked first piece with x and second with y
x + y = 42
Given ratio is x : y = 3 : 4
From this proportion we get
x = 3 c and y = 4 c where c is coefficient of proportionality
when we replace this in initial equation we get
3 c + 4 c = 42 => 7 c = 42 => c = 42/7 = 6 c = 6
x = 3 · 6 = 18 inches and z = 4 · 6 = 24 inches
shorter piece is x = 18 inches
God with you!!!
The answer might be Y=1/4x+2
Answer: x
=
9
