Answer:
80
Step-by-step explanation:
Use the equation 180-(70 +30)
Equation:
distance + distance = 2250 miles
3x + 3(x-110) = 2250
6x - 330 = 2250
6x = 2580
x = 430 mph (rate of the westbound plane)
x-110 = 320 mph (rate of the eastbound plane)
PLS MARK BRAINLIEST!!!
Where is the graph I need to see the graph for the answer
Answer:
x=280
Step-by-step explanation:
We have, 15% × x = 42
or,
15
100
× x = 42
Multiplying both sides by 100 and dividing both sides by 15,
we have x = 42 ×
100
15
x = 280
If you are using a calculator, simply enter 42×100÷15, which will give you the answer.
