Answer:

Step-by-step explanation:

2/5x + 4 = 1/5x + 8

(subtract 1/5x from both sides)

1/5x + 4 = 8

(subtract 4 from sides)

1/5x = 4

(multiply by 5 from both sides of the equation to isolate x)

x = 20

10. Make q the subject of the formula 5(q + p) = 4 + 8p

vichka [17]

The formula subject to q is $\frac{4+3p}{5}$

Explanation:

The given formula is $5(q+p)=4+8 p$

We need to determine the formula subject to q.

<u>The formula subject to q:</u>

The formula subject to q can be determined by solving the formula for q.

Let us solve the formula.

Thus, we have;

$5q+5p=4+8p$

Subtracting both sides by 5p, we have;

$5q=4+3p$

Dividing both sides by 5, we get;

$q=\frac{4+3p}{5}$

Thus, the formula subject to q is $\frac{4+3p}{5}$
