Grayson's mistake was that he multiplied 4 and 3 and then used the exponent he had to square 3 and then multiply it by 4.
Emily's mistake was that she added 2 to 36 instead of multiplying it by -2
Pat's mistake was that he forget to make y into -2 instead of 2
The right way to do this is 4(3^2)+2(-2)
(3^2)=9 9×4=36 2(-2)=-4 -4+9=5
Answer:
I will: Multiply 32 times 20 to get the total cost of the foods and tickets. Then I will add the total cost of the tickets and the total cost of the bus to get the total cost of the trip. Lastly I will divide the total cost of the trip by 2 to find out how much money the class need to earn.
Solution: 32 • 20 = 640 + 900 = 1,540 ÷ 2 = 770
Answer: 770
20 tulips. 2/3=20/30 when you multiply both the denominator and numerator by 10.
Given:
The equation is
To find:
The coefficient and reciprocal.
Solution:
We have,
Here, 
is multiplied with x.
So, the coefficient of x is .
To find the reciprocal, we need to interchange numerator and denominator of a fraction.
So, the reciprocal of is 
Therefore, the reciprocal is 3.
