Simplified<br> Quickly please
UkoKoshka [18]

Answer:

3a:20d+35

3b:35u+49q+56

4a:15+20t

4b:96k+120t+84

5a:24t+108m+60

5b:56q+28b+35

6a:14q+10w+24

6b:54v+99+27t

7a:16g+24+24c

7b:30a+55+50d

(i think thats what they are but the picture is small so its kind of hard to see)

Step-by-step explanation:

(since theres 10 total ill just give an example on how i solved 5a)

5(4d+7)

simplify into: (5•4d)+(5•7)

multiply: (20d)+(35)

since you do not know what d is, you cannot add them

remove parentheses once done:20d+35

(you don't need parentheses since multiplication come before addition but its easier to just use them)

To do these, always convert the percents to decimals, so you can subtract it from 1. Remember, 1 is the whole. When you subtract the part that's taken off, you are left with what you have to pay. If you have 20% off of $100, then you are paying for 80% of $100. **of means to multiply** so you would multiply: 0.8X100, which would be $80.

First, multiply 125x0.8

Multiply that answer by 0.7

You should get B. $70

3) multiple 22.90x0.93

You should get D
