Answer:
9.8 lbs
Step-by-step explanation:
4 1/3 + 5 5/6= 10 1/6
20 - 10 1/6 = 9.8
AC is parallel to MN then triangle ABC and triangle MBN are similar and the ratio of the corresponding sides are equal...
Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.
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.
