Answer:
$2.25 per ft² (I think)
Step-by-step explanation:
Subtract 4.9 from 6.4 to get 1.5
Multiply 6.4 by 1.5 and multiply 4.9 by 1.5
Then you get 9.6 and 7.35
Subtract 7.35 from 9.6 and get 2.25
A+3=B
17+3=B=20
B equals 20 when A equals 17
10(x2) = 70(x)
10x2 - 70x
10x = 70

Answer:


Step-by-step explanation:

Move x / 4 to left hand side and change its sign
Similarly, move 2 to right hand side and change it's sign

Take the L.C.M of 3 and 4
L.C.M of 3 and 4 = 12



Subtract 2 from 3

Do cross multiplication


--------------------------------------------------------------------

Distribute 3 through the parentheses

Move x to left hand side and change it's sign
Similarly, move 12 to right hand side and change it's sign

Collect like terms

Subtract 12 from 33

Divide both sides by 7

Calculate
