Answer:
length: 200
width: 65
Step-by-step explanation:
length: 3w + 5
width: w
perimeter = 2L + 2W
530 = 2(3w + 5) + 2w
530 = 6w + 10 + 2w
530 = 8w + 10
520 = 8w
w = 65
length: 3w + 5 = 3(65) + 5 = 200
width: w = 65
Answer:
9 7/8
Step-by-step explanation:
solution by separating parts:
1) rewrite equation with parts separated
= 6 +1/4 + 3 + 5/8
2) solve whole number parts
6 + 3 = 9
3) solve fraction parts
1/4 + 5/8 = ?
- find the LCD of 1/4 and 5/8 and rewrite to solve
LCD = 8
2/8 + 5/8 = 7/8
combining the whole and fraction parts:
9 + 7/8 = 9 7/8
It equals -1
you have collect like terms the -7w+w
which give you -6w then you have to divide both sides by -6
which gives you -1
