Step-by-step explanation:
350÷5 will give you quarters. 350÷50=70. 70x4=280
If you wanted to paint the entire door (even the top and bottom which people don't usually paint)
the surface area is
SA=2(LW+LH+WH)
where L=length, W=width and H=height
given
L=35.25
W=1.75
H=77
SA=2(35.25*1.75+35.25*77+1.75*77)
SA=2(61.6875+2714.25+134.75)
SA=2(2910.6875)
SA=5821.375
you need enough paint to cover 5821.375 square inches of door
Answer:
We conclude that the equivalent expression is:

Step-by-step explanation:
Given the expression

Remove parentheses: (a) = a

Multiply the numbers: 3 × 2 = 6

Multiply the numbers: 4 × 5 = 20

Multiply the numbers: 4 × 2 = 8

Thus, we conclude that the equivalent expression is:

207$ - 15$ = 192$
192$ : 8 = 24$
Answer: Each book costed 24$.
