Answer:
1. If x=5, 3*5=15, 15*15=225 + y (3) = 228.
2. If y=4, then 10*4 = 40, 4^2 is 16, so 40 + 16 is 56.
I might be wrong, but the first one you answered, x^2, x= 1/2, I think that is wrong. when something is squared, you don't go, "Oh, well since 1/2 equals 1, that's the answer." The way to figure out something like this is... 1/2 times 1/2, which is .25, or 1/4. Another example: 3^5 . The way to find this out is 3*3*3*3*3 = 243. But you don't go 3*5, because that answer would be 15, which is not correct.
2.6/1.3 * (10^9/10^2)
2*10^7
<span>c =0.20m + 2.00
Where c is the cost and m = number of miles,
For a 2.7 mile ride, m = 2.7
</span>
<span>c = 0.20m + 2.00, m = 2.7
</span>
<span>c = 0.20*2.7 + 2
c = 0.54 + 2
c = 2.54
Charge for the ride = $2.54
I hope this helps.

Yes good job you are correct
