C
Step-by-step explanation: hope this helps :)
Answer:
which agrees with answer B
Step-by-step explanation:
First write the equation that represents this type of variation:
then we need to solve for "x" when y = 10 as shown below:
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.
The constant term in the equation is -20 because you will always be subtracting 20 no matter how big x is
Answer is P=3.5 or p=7/2
They are both correct
