Answer:47/20 or 2.35 in decimal form
Step-by-step explanation:
Answer:
8-14 or -6
Step-by-step explanation:
X-x-2/6=x-7/3+2/3
-2/6+7/3-2/3=x
x= -2/6+5/3
x= 8/6
x= 4/3
So, she buys 16 bags, each of them weights
pounds.
to find how many pounds of soil she bought, we have to multiply:
16*
=//16 is equal to 8*2, so we can simpify:
2*
which is 2*5=10
so in the end she bought 10 pounds of soil!
Answer:
6; 22; 20 (ft.)
Step-by-step explanation:
1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.
2) if according to the condition perimeter is 48 (ft.), then
9n-6=P; ⇔ 9n-6=48; n=6.
3) if n=6, then the required lengths of the sides are:
n=6 (ft.);
4n-2=22 (ft.);
4n-4=20 (ft.)
