Some symptoms can be treated with antibiotics but the disease will not go away completely
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
Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0
An example:
2(x + y) + 4 = (4x + 4y + 8)/2
2x + 2y + 4 = 2x + 2y + 4
0 = 0
Answer:
x=120 degrees
Step-by-step explanation:
Because these two angles share the two same points, either one is 2x larger or 2x smaller than the other. X is the larger angle, therefore is 2x larger than 60. 60×2=120. I hope this helps you!
