How do I solve |5-3p|+9=13p+8

anastassius [24]

Answer:

p = -2/5 or 3/8

Step-by-step explanation:

|5 − 3p| + 9 = 13p + 8

|5 − 3p| = 13p − 1

If 5 − 3p is positive:

5 − 3p = 13p − 1

6 = 16p

p = 3/8

If 5 − 3p is negative:

-(5 − 3p) = 13p − 1

-5 + 3p = 13p − 1

-4 = 10p

p = -2/5

Alternatively, we can square both sides of the equation:

(5 − 3p)² = (13p − 1)²

25 − 30p + 9p² = 169p² − 26p + 1

0 = 160p² + 4p − 24

0 = 40p² + p − 6

0 = (5p + 2) (8p − 3)

p = -2/5 or 3/8

maksim [4K]

Answer:

Equation: $P = 10n$

$P = 40$ when n = 4

Step-by-step explanation:

Given

Direct Variation: P ∝ n

When n = 15, P = 150

Required

Determine the equation

Her earnings if she sold 4 necklaces

P ∝ n

Convert variation to equation

$P = kn$

When P = 150, n = 15 (Substitute these values in the given equation)

$150 = k * 15$

Divide both sides by 15

$\frac{150}{15} = \frac{k * 15}{15}$

$10 = k\\k = 10$

Substitute k = 10 in $P = kn$

$P = 10 * n$

$P = 10n$ ------- Equation that relates P and n

When she sold 4 necklaces, n = 4

Substitute n = 4 in the formula above

$P = 10 * 4$

$P = 40$
