The sum of two numbers is 20. The larger number is 5 more than the smaller number. What are the two numbers

Larger number = 12.5, Smaller # = 7.5

Step-by-step explanation:

let L = larger #

let S = smaller #

L + S = 20

L = S + 5 (Because L is 5 more than S)

Plug in L

S + 5 + S = 20

2S + 5 = 20

2S = 20 - 5

2S = 15

(divide both sides by 2)

S = 7.5

L + 7.5 = 20

L = 12.5 (because 20 - 7.5 = 12.5)

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

i just took the test, the correct answer is .. 31.5 in.
