21. 0.25x - 1.25 - 3x + 2 = -2.75x + 0.75
22. 15/100= 0.15. 0.15•64,000= 9,600. The answer is D.
23. 1,200-300= 9,000. 1,200+300= 15,000. 9,000/15,000= 3/5. 3/5= 0.6. 60% of the building is aboveground.
24. The patterson seems to be the y=18x and when you plug 7 in to the equation, you get 126, not 128, so D is the answer.
Solving for x...

Times the

, both the numerator and denominator, by 8 to get the denominator to 16.
Times the

, both the numerator and denominator, by 4 to get the denominator to 16.
Then rewrite the problem,

now that the denominators are all the same, you can solve...
subtract the

from both sides
you should get

Multiply both sides by 16 (it'll cancel both the 16 out making it go away)
8x = 11
divide each side by 8 to have the x alone
<u>8x</u> = <u>11
</u> 8 8
<u>
</u> You should end with x =

Answer:
a)8×83/100%
=8×83
=664
=664÷100%
=6.64%
b)2×83/100%
=2×83
=166
=166÷100%
=1.66%
c) a+b
=6.64%+1.66%
=8.3%
=8%
Step-by-step explanation:
a)8 debit card Customers × 83 cash ÷ 100%
=664÷100%
=6.64
b)2 credit card×83cash÷100%
=166÷100%
=1.66%
c) a+b
=6.64+1.66
=8.3%
=8%
Answer:28
Step-by-step explanation:
If she can invite only 45 and 17 are family just subtract 45 from 17 which is 28 she can Invite 28 more people
The angles of a triangle always equal to 180 degrees.
Knowing this, you can solve this by this equation
Angle A + Angle B + Angle C = 180
43 + 85 + Angle C = 180
Angle C = 180 - 43 - 85
Angle C = 52
