S=2(lw+lh+wh) solve for w
wolverine [178]

we have

s=2(lw+lh+wh)

Solve for w means that clear variable w

s=2(lw+lh+wh)\\s=2lw+2lh+2wh

Group terms that contain the variable w, and move the other terms to the opposite side of the equation

(s-2lh)=(2lw+2wh)

Factor the variable w

(s-2lh)=w(2l+2h)

Divide both sides by (2l+2h)

(s-2lh)/(2l+2h)=w(2l+2h)/(2l+2h)

w=(s-2lh)/(2l+2h)

therefore

<u>the answer is</u>

w=(s-2lh)/(2l+2h)

6 sweets cost 42p altogether how much do 8 sweets cost
Eddi Din [679]
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.
