Answer:
Determine whether each function represents exponential growth or decay
If a is positive and b is greater than 1 , then it is exponential growth. If a is positive and b is less than 1 but greater than 0 , then it is exponential decay.
Step-by-step explanation:
33 + 87 + x = 180
120 + x = 180
x = 60
y + x = 180
y + 60 = 180
y = 120
Answer:
the left hand side dose not equale 7a^7
Step-by-step explanation:
4a^2x3a^5=7a^2+5=7a^7
16ax3a^5=7a^7=7a^7
48a^5=7a^2+5=7a^7
First person = 10 min
Second person = 15 min
Time together = x
Equation Formation
x = (10+15) ÷2
x = 12.5
Answer = 12.5 minutes
Amount of Job done by the slowest person.

Answer = 40%
Answer:
55 cents.
Step-by-step explanation:
First, we start off with a half dollar (50 cents), and add a quarter (25 cents). 50 + 25 = 75. Next we take two dimes (each dime being 10 cents). 10 + 10 is 20, so we have twenty cents in dimes. It says to subtract the 2 dimes from our current number 75 minus 20 is 55. Therefore, we have 55 cents left. (If needed, that is 1 half dollar and 1 nickel.)
Hope this helps! :D
