Answer:
60
Step-by-step explanation:
Steps to solve "54 is 90 percent of what number?"
We have, 90% × x = 54
or,
90/100 × x = 54
Multiplying both sides by 100 and dividing both sides by 90,
we have x = 54 × 100/90
x = 60
If you are using a calculator, simply enter 54×100÷90, which will give you the answer.
Answer:
y=x +3
Step-by-step explanation:
this is the equation because it shows the actual relationship between x and y
Jen take x hours.
Carl (x-3)hours.
Jen+carl take two hours;
This means;
In 1 hour, for they work

=

=

Working together, they take two hours;
Take reciprocal of above equation and equate to two;
=


-3x=4x-6


-x-6x+6=0
x(x-1)-6(x-1)=0
(x-6)(x-1)=0
Take the bracket x-6=0 so that Carl works positive hours
x-6=0
x=6
