Answer: 7
7 is the middle number when the number are out from least to greatest. Hope that helps!!
Actually, the domain is the possible set of input values
of a function that will make the function fit the specific criteria. In this
case, the input value is m, where m is the number of miles that is travelled.
The criteria is to travel at least 10 miles but not more than 30 miles,
therefore the domain should be:
All real numbers from 10 to 30, inclusive
(should be real numbers not integer since any fractional
number is included in the domain)
I cannot figure out why the choices are far from the
answer.
3(x+2)+11>20
minus 11 both sides
3(x+2)>9
divide both sides by 3
x+2>3
minus 2 both sides
x>1
Answer: She has 76 dimes and 78 quarters.
Step-by-step explanation:
Given data:
Total = $27.20
Solution:
Q = d + 2
Each quarter is 25 cents, or 0.25 of a dollar = 0.25q
Each dime is 10 cents = 0.10d
0.25q+0.10d = $27.20
Where q = d-2
Substitute in this equation:
0.25(d+2)+0.10d = 27.20
0.25d + 0.5 + 0.10d = 27.20
0.35d = 26.7
Divide both sides by 0.35
d = 76
She has 76 dimes and 76 + 2 = 78 quarters.
