The delivery truck can travel 738 miles on 41 gallons of gas, assuming it maintains the same fuel efficiency. This is calculated by first finding the mileage per gallon (miles driven divided by gallons used), then multiplying that by the number of gallons.
The situation given can be solved by using unit rate or sometimes referred to as proportion. The delivery truck traveled 324 miles on 18 gallons of gas. We'll first find out the mileage per gallon and then use that to compute how far it could go on 41 gallons.
So, a delivery truck that traveled 324 miles on 18 gallons of gas could travel 738 miles on 41 gallons of gas, assuming the truck maintains the same fuel efficiency.

B) b = c + 0.5
C) 3a + c = 10
D) a + 2c = 10.5
Answer: Option 'D' is not correct.
Step-by-step explanation:
Since we have given that
Total distance walked by Adam , Beth, and Carly = 10 miles
Let number of miles Adam walks be a
Let number of miles Beth walks be b
Let number of miles Carly walks be c
According to question,
Beth walked twice as far as Adam
So, the equation will be
Thus, Option 'A' is satisfied.
Now, Beth walked a half a mile further than Carly.
So, the equation will be
Thus, Option 'B' is correct.
Now, we substitute the first equation, then we get
Thus, Option 'C' is correct.
The only incorrect equation is Option 'D' .
Answer:
1.72 grams.
Step-by-step explanation:
We have been given that Gomez found the masses of three rocks for a science project. The first rock had a mass of 19.28 grams the second rock had a mass of 25.3 grams and the third rock had a mass of 46.3 grams.
First of all, we will add the masses of 1st and 2nd rock to find the combined mass of both rocks.
Now we will subtract the combined mass of both rocks from the mass of 3rd rock.
Therefore, the mass of the 3rd rock is 1.72 grams greater than the combined mass of the other two rocks.
Step-by-step explanation:
Simply you replace X and Y by their values
Given: x=-1 y=-4
10 - (-X)^3 + y^2
=10 + X^3 + Y^2
Now replace X and Y
=10 + (-1)^3 + (-4)^2
=10 - 1 + 16
= 25
