Answer:
161 miles
Step-by-step explanation:
We need to first find the number of miles the car can travel in 1 gallon. Then we will mulitply that with 7 to get number of miles travelled in 7 gallons.
To find unit rate, we divide number of miles travelled (184) by number of gallons used (8). So
Miles per gallon = 184/8 = 23 mpg
Thus, is 7 gallons, it would travel:
7 * 23 = 161 miles
Answer:
<u>The cost per gallon is US$ 1.87</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Number of gallons of gas = 13
Cost of the gallons of gas = US$ 24.31
2. What is the cost per gallon?
Cost per gallon = Cost of the gallons of gas/Number of gallons of gas
Replacing with the real values, we have:
Cost per gallon = 24.31/13
Cost per gallon = 1.87
<u>The cost per gallon is US$ 1.87</u>
Answer:
Step-by-step explanation:
Given equations are
15x + 15y + 10z = 106
5x + 15y + 25z = 135
15x + 10y - 5z = 42
The augmented matrix by using above equations can be written as
Hence, we can write from augmented matrix,
Answer:
d= 3h-6
Step-by-step explanation:
h= d/3+2
h-2= d/3
d= 3(h-2)= 3h-6
Y=2x(4+3)-2
=2x7-2
=14-2
=12
