Answer:
16.5 hours
Step-by-step explanation:
The bicycle costs $240. Eva already has $42. She is making $12 per hour.
240 = 12x + 42
Solve for x to find out how many hours Eva needs to work to buy the bicycle.
240 = 12x + 42
240 - 42 = (12x + 42) - 42
198 = 12x
198/12 = (12x)/12
16.5 = x
Eva needs to work 16.5 hours to be able to buy the bikw.
3x4x1/2= 6inches Multiply the base by the height and after multiply by one half
Slope of 3 mean y=3x
to find the equation we say y=3x+C then sub -2 for x and -8 for y to find the C
-8=3*-2+C
-8=-6+C
-8+6=C
-2=C
so equation would be: y= 3x-2
Answer: the others are 5cm and 8cm
Step-by-step explanation:
this is because a rhombus is the same as a rectangle or square and they have equal two sides
Answer:
Ann drove 312 miles in 8 gallons.
Step-by-step explanation:
Distance covered by Ann's car = 117 miles
Gallons of gas spent by Ann's car to cover 117 miles = 3 gallons
Unit rate = 117 miles / 3 gallons
= 39 miles per gallon
so Ann's car can go 39 miles in one gallon of gas.
- Given that Ann used 8 gallons of gas.
Therefore,
Distance covered by Ann's car in 8 gallons = 39 × 8
= 312 miles
Therefore, Ann drove 312 miles in 8 gallons.
