If you would like to know if Miles is going to spend more or fewer hours bicycling this week than last week, you can calculate this using the following steps:
2/3 as many hours:
2/3 * x hours
Because 2/3 is less than 3/3 = 1, this means that Miles is going to spend fewer hours bicycling this week than last week.
If you have an EFI system in your car, you're not supposed to press the accelerator because fuel gets pumped into the engine electronically. It is automatic. Having to press the accelerator before is a mark of older vehicles. Just start the vehicle regularly without pressing anything or doing anything special.
Answer:
135
Step-by-step explanation:
2 x 54 = 108 and .50 x 54 = 27 so 108 + 27 = 135
Y= 150
Start by using substitution.
Change x+y=375 to x=375-y
Substitute this into 1.25x+0.75y=393.75
1.25(375-y)+0.75y=393.75
Distribute the 1.25
468.75-1.25y+0.75=393.75
Add like terms (y)
468.75-0.5y=393.75
Subtract 468.75 to the right
-0.5y=-75
Divide by -0.5
y=150
