Answer: C
<u>Step-by-step explanation:</u>
5(z - 4) - z = 4z - 20
<u>5z</u> - 20 <u>- z</u> = 4z - 20
4z - 20 = 4z - 20
<u>-4z </u> <u>-4z </u>
-20 = -20
TRUE
Since it is a true statement, there are infinitely many solutions

Answer: D
<u>Step-by-step explanation:</u>
Eric: 1 hot dog
Mark: 1 hot dog + 1 soda + 1 peanuts
Total: 2 hot dogs + 1 soda + 1 peanuts
= 2(3.50) + x + 1(4.00)
= 7.00 + x + 4.00
= x + 11.00
Eric paid 3.00: x + 11.00 - 3.00
x + 8.00
Mark paid 11.50 which was the balance owed: 11.50 = x + 8.00
11.50 = x + 8.00
<u>-8.00</u> <u> -8.00 </u>
3.50 = x
the soda cost $3.50
Answer:
65.5 feet per second
Step-by-step explanation:
In order to calculate the rate of descent we first need to find the difference in heigh that the hot air balloon descended. We do this by subtracting the initial height from the end height like so...
6,039 - 3,288 = 2,751 ft
Now that we have the difference in height we need to divide this by 42 since that is the amount of time it took for this descent to occur.
2,751 ft / 42s = 65.5 ft/s
Finally we can see that the rate of descent was 65.5 feet per second
<span>The first two cuts can intersect at only 1 pt regardless of where they are placed.
So 4 pieces there.
The last cut can only intersect each other cut a 1 pt, regardless of placement. As long as the intersection is different than the first intersection, then you will have 7 pieces.</span>
