Answer:
Step-by-step explanation:
The new bike costs 180 dollars
Parents paid 40%
what is a percentage? per cent= divide by 100
parents paid 180 *40/100=180*0.4=72 dollars
Jennifer has to pay the rest
180-72=108
You can see it’s 90
You can also see it because. A triangle is 180 degrees so
45+45=90
180-90=90
So x=90
Answer:
33
Step-by-step explanation:
a right angle is 90 degress since the other side is 57 than ac must be 33
Answer:
q=(40-7)/3 or simplified q=11
Step-by-step explanation:
So we know that the perimeter is 40 inches and one of the sides is 7 so logically we do 40-7 to get the length of the three remaining sides combined. Then to find the length q, we have to divide that answer by 3 because the three sides have the same length or (40-7)/3, which simplified is 11, so the length of the side is 11 inches and the expression is q=(40-7)/3.
5*4^2-3*4*5=80-60=20
Hope that helps you
