Define x:
------------------------------------------------------
Let the number of shells Carron collected be x.
Carron = x
Mandee = 4x
------------------------------------------------------
Construct Equation and solve x:
------------------------------------------------------
x + 4x = 40
5x = 40
x = 8
------------------------------------------------------
Find the number Carron and Mandee have:
------------------------------------------------------
Carron = x = 8
Mandee = 4x = 4(8) = 32
------------------------------------------------------
Answer: Mandee collected 32 shells.
------------------------------------------------------
He spent 0.25 dollars or 25 cents
Answer:
A. -1/5
B. 8 gallons
C. 75 miles driven
Step-by-step explanation:
Part A is essentially just asking for the slope, which is written as a fraction with the numerator being the number of units the line goes up/down and the denominator being the number of units the line goes left/right. Because the line is going down from left to right, the slope is negative. The slope is -1/5.
Part B can be answered by simply looking at the graph and seeing where the line is at above 175 miles, which is 8 gallons.
Part C can be answered in the same way as Part B, by looking at where the line is at when level with 12 gallons, which is 75 miles driven.
Answer:
300/1500, 1/5, or 20%
Step-by-step explanation:
There are 1500 students total, but only 300 engineering students. We can represent this as a fraction: 300/1500. When reduced it comes out to 20%.
