Answer:
it's rational
Step-by-step explanation:
4. C)If two figures are congruent, then they are similar.
If they are congruent them shape and size are the same and hence they are similar
5. Ratio 4/3 smaller side is 21
Multiply to find large side
4/3×21= 28ft D)
6. Width went from 24 to 3 in divide to get ratio
24/3 =8 now divide the length by 8 to find the postcard length
32/8= 4 in A)
8. If they are similar you need to find the ratio y reduces from 8 is similar to 6 so link those 6/8
This is your ratio you can simplify it to 3/4 now y/6 should also = 3/4
Y/6=3/4
Y=18/4= 4.5 C)
9.C)DC
Dealer's cost + 5% = 23,727.90
(1 + .05) dealer's cost = 23,727.90
Dealer's cost = 23.727.90 / 1.05 = <u>22,598</u>

Given: 
Find: 
Solution: In order to solve for x we need to isolate it with the first step being to subtract 1 from both sides and then we would divide both sides by 3 to give us the solution.
<u>Subtract 1 from both sides</u>
<u>Divide both sides by 3</u>
Therefore, the final answer would be that x is equal to -1/3.
