First you had to multiply with negatives seven and negative five. You can also multiply by the numbers.

-7*-5=-35

Final answer: \boxed{=-35}

35/5=7

7*5=35

5*7=35

35/7=5

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Hello!

Let’s do it step-by-step, shall we? Don’t worry! These problems can be a bit tricky but you’ll get it in no time! It’s really simple.

So, we have (-7)(-5)

This means that the problem will be multiplied because of the parentheses. They substitute the multiplication sign.

So, we have -7 (multiplied by) -5= 35

So your answer would be 35. Hope this helps :) and good luck!

Assuming you're solving for <em>n</em>, 1. n=-1 2. n=-1.6

Step-by-step explanation:

1. -5(2-5n)+6=-5n-34-2

Distributive Property

-10+25n+6=-5n-32-2

Add Like Terms

-4+25n=-5n-34

Subtract -4

25n=-5n-30

Subtract -5n

30n=-30

Divide by 30

n=-1

2. -5(2-5n)+6=-5n-34-20

Distributive Property

-10+25n+6=-5n-32-20

110 as a product of prime numbers
sweet [91]
110 = 11 \times 10

110 = 11 \times \ 5 \times 2

So it is the product of 5 \times 2 \times 11

And 2,5 and 11 are prime numbers, so there you go :)

HELP ASAP! WILL GIVE BRAINLIEST IF YOU GIVE A REASONABLE ANSWER
Semenov [28]

Answer:

Step-by-step explanation:

Part A: Company A charges $6 for a window and $12 for a service clean. If you add that up it would be 6 + 12 =18 so company A would be making $18 per customer. Company B charges $15 + $5 for a whole cleaning which would make them $20 per customer. That is better then $18 so business B would be making more money.

Part B: For cleaning 8 windows company B would charge less because 8 x 5 = $40 for all the windows and company A would be charging $6 for a window which is more so 8 x 6 = 48. Company B charges less.

Part C: Company B charges 5 dollars for thier services on windows as Company A charges 6. You would be saving a dollar by buying at company B.
