Answer:
one solution
Step-by-step explanation:
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.

Answer:
-2/3
Step-by-step explanation:
multiply each side by u +1 to get it out of the denominator
-3(u + 1) = -1
now use distributive property
-3u - 3 = -1
add the 3 to move it over
-3u = 2
now divide by -3
u = -2/3
