Remember distance divided by time so 105/90 =1.17
Answer:
The constant of proportionality is k = 7/6 or 1.16
Step-by-step explanation:
Sorry if I'm wrong! I'm just learning this subject too so I'm going off what my teacher has told us.
Simplest way to do this:
number of books= 120
percentage represented by 120= 100%
increase current percent by 55%= 155%
: . 55% increase = original number of books * (155%)
= 120 * (155/100)
= 186
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
