My solution: P.S I’m not sure if I’m correct.

2L+2W=120
2*3W+2W=120
6W+2W=120
8W=120
W=120/8
W=15 M. FOR THE WIDTH.
L=3*15=45 M. FOR THE LENGTH.
PROOF:
2*45+2*15=120
90+30=120
120=120

Hope this solution works! If not, I’m very sorry. :(

A glass is 4/7 full . Then 70cm3 of orange juice is poured in . The glass is now 2/4 full. What is the total volume of the glss
Korolek [52]
Let 
x--------------> total volume of a glass

we know that
(4/7)x-70=(2/4)x------------> (4/7)x-70=(1/2)x--------> 2*(4/7)x-2*70=x
(8/7)x-140=x

<span>multiplied by 7 the expresion
</span>7*(8/7)x-7*140=7*x-----------> 8x-980=7x--------> x=980 cm³

the answer is 
<span>the total volume of the glass is 980 cm</span>³

What is the solution to the equation -5 =8m +12 /4
Dima020 [189]
m = -1

-5 = 8m + 12/4
-5 - 12/4 = 8m
4(-5) - (12/4) = 4(8m)  
 
*to remove the denominator, multiply each figure by 4.

-20 -12 = 32m
-32 = 32m
-32/32 = 32m/32
-1 = m

m = -1

To check:

-5 = 8m + 12/4
-5 = 8(-1) + 3
-5 = -8 + 3
-5 = -5
