Ответ:
to solve the equation first cross multiply.
x*5=40*2
x*5=80
now divide both sides by 5, 80 divided by 5 is equal to 16.
so the number of girls in the computer lab is 16.
Ответ:
Domain: All real numbers
Range: All real numbers
Step-by-step explanation:
Domain is all the x-value inputs that can be used in the equation.
Range is all the y-value outputs that can be used in the equation.
Since the equation is linear, any value of x and y would work for both domain and range, so both are (negative infinity, positive infinity).
