Answer:
Step-by-step explanation:
If u are saying 12/5, 5 goes into 12 2 times which is 10. there is 2 left so it is 2 and 2/5
We have 2l + 2w = 120 and l/w = 2/3;
Then, l = (2/3)w;
Finally, (4/3)w + 2w = 120;
4w + 6w = 360;
10w = 360;
w = 36;
l = (2/3)x36;
l = 24;
Here we go ~
[ add 2 on both sides ]
[ form identity : a² + b² + 2ab ]
[ a² + b² + 2ab = (a + b)² ]
so, the value of required expression is 6
[usually positive value is considered, but if asked the value can be either positive or negative]
Answer: F=140
Step-by-step explanation:
720=(x-60)+(x-40)+(x-20)+130+120+110
720-130-120-110=3x-120
360=3x-120
360+120=3x
480=3x
480/3=x
160=x
F=160-20
Next problem
102+31+x=180
133+x=180
x=180-133
x=47
$5 → 1/3 pound
$1 → 1/3 ÷ 5 = 1/3 x 1/5 = 1/15 pound
$9 → 1/15 pound x 9 = 9/15 pound = 3/5 pound
