Plug y= x+5 in 3x+y= 25, we have:
3x+ (x+5)= 25
⇒ (3x+x)+ 5= 25 (combine like terms)
⇒ 4x= 25-5
⇒ 4x= 20
⇒ x= 20/4
⇒x= 5
y= 5+5= 10
Final answer: x=5, y=10~
I think it’s either 180 or 360
Answer:
B. 1,500’
Step-by-step explanation:
Given;
dimension of the rectangular house, = 35’ x 40’
The actual total linear footage of lumber needed = 35’ x 40’ = 1,400'
The rough estimate should be greater than the actual estimate in 100s;
rough estimate = 1,400' + 100' = 1,500'
Therefore, the rough estimate of the total linear footage of lumber needed is 1,500'.
