a car travels along a straight road to the east for 150 meters in 4 seconds and west for 50 meters in one second
Answer:
B) 7 gallons
Step-by-step explanation:
car begins with 12 gallons and, at a rate of 29 mpg, would allow the car to travel for 348 miles
car only traveled 140 miles so 208 miles more can be driven
208÷29 is approx 7 gallons
C. Above the dashed line.
It becomes:
y > 1/2x +3/2
(Dashed, shaded above)
Answer:
a=15x; b=8x; c=13x
180°=a+b+c=15x+8x+13x=36x
=> x=180÷36=5
=> a=15×5=75°; b=8×5=40°; c=13×5=65°
Answer:
*Assuming that the question should read '8 years less than 3 times Danielle's age'*
Equation: 3a - 8 = 34, where 'a' = Danielle's age
Danielle's age (a) = 14
Step-by-step explanation:
Using key words and phrases from the problem, we can find Danielle's age by setting up an equation to solve for 'a'.
Since Danielle's aunt is '8 years less than 3 times Danielle's age' her aunt's age can be written as: 3a - 8. We also know her aunt is 34. So, the equation becomes:
3a - 8 = 34
Add 8 to both sides: 3a - 8 + 8 = 34 + 8 or 3a = 42
Divide both sides by 3: 3a/3 = 42/3
Solve for a: a = 14, so Danielle's age is 14 years old.
