What is the value of the expression?

1 answer:

7 0

Must do multiplication first....
-2/5 - 3/7 x 7/10
-2/5 - 21/70 (I'll reduce 21/70)
-2/5 - 3/10
Now you have to find a common denominator and subtract
-35/50 = -7/10......is what I get

The perimeter of a basket ball court is 108 m and the length is 6 m long than twice the width. What are the length and the width

Gnoma [55]

Let's say

P = perimeter, L : Length and w : width

Then

$P=2(L+w)=2L+2w=108$

But

$L=6+2w$

So

$2L+2w=108\\2(6+2w)+2w=108\\12+4w+2w=108\\12+6w=108\\6w=108-12\\6w=96\\w=16$

$L=6+2w\\L=6+2(16)\\L=6+32\\L=38$

We verify :

$2L+2w=108\\2(38)+2(16)=108\\76+32=108\\108=108$

Length = L = 38
Width = w = 16
