We can create equations to solve this.

2.50p + 1.50m = 29.50
p + m = 15

Solve for a variable in the 2nd equation and use the substitution method to solve.

p + m = 15

Subtract p to both sides:

m = -p + 15

Plug in -p + 15 for m in the first equation.

2.50p + 1.50(-p + 15) = 29.50

Distribute:

2.50p - 1.50p + 22.50 = 29.50

Combine like terms:

p + 22.50 = 29.50

Subtract 22.50 to both sides:

p = 7

Now plug this into any of the two equations and solve for the other variable.

p + m = 15

7 + m = 15

Subtract 7 to both sides:

m = 8

So he purchased 7 pineapples and 8 mangos.

Write your answer without using negative exponents.<br> (w^5)^-7

Blababa [14]

Answer:

1/(w^35)

Step-by-step explanation:

According to the rules of exponents, you need to multiply both -7 and 5 such that you get...

w^(-35)

Since you cannot have a negative exponent according to the question, you simplify by...

w^-x means that you do 1/(w^-x)

1/(w^35)
