Tell you what I'll do: I'll show you the work, for two of them.
Then, knowing how to do it, you'll find the answers.
Deal ?

#1). n + (-13) = -12

Remove the parentheses
on the left side: n - 13 = -12

Add 13 to each side: n = 1

================================

#3). -15 + n = 3

Add 15 to each side: n = 18

OK. Look those over, understand how they're done, then TAKE IT !

2:5 and 30:20 are equal ratios. True or false

Answers

The answer is false.
For being in equal ratios, product of means = product of extremes
2:5 :: 30:20
2 × 20 = 30 × 5
40 ≠ 150
So, its false since they are unequal.

I believe from what i have learned from over the years that your answer should be c

Frank and Gertrude mow lawns for extra money over the summer. Frank's income is determined by f(x) = 5x + 15, where x is the number of hours. Gertrude's income is g(x) = 4x + 20. If Frank and Gertrude were to combine their efforts, their income would be h(x) = f(x) + g(x). Assume Frank works 4 hours. Create the function h(x) and indicate if Frank will make more money working alone or by teaming with Gertrude.

Answers

find h(x)
f(x)+g(x)=5x+15+4x+20=9x+35

ok so if gertrude works 4
f(x)=5x+15
f(4)=5(4)+15
f(4)=35

if we input 4 for x in f(x) to find how much made togethe rin 4 hours
h(4)=9x+35
h(4)=9(4)+35
h(4)=36+35
h(4)=71

split evenly?
71/2=35.5

frankalone=35 for 4 hours
frankwithgertrued=35.5 for 4 hours

Answer:
