She sliced 7 pizzas as there are 7 slices per pizza so 49/7 is 7
Step-by-step explanation:
Given the average of 8 numbers = 56.
Then the Total sum of 8 numbers = 56 * 8
= 448.
Sum of 1st three numbers = 49 + 57 + 72
= 178.
So, the total = 448 - 178
= 270.
Average of the other 5 numbers = 270/5
= 54.
Verification:
178 + 270 = 448/8
= 56.
Answer:
The probability is 1/2 or 50%
Step-by-step explanation:
We have 3 numbers that are divisible by 2 (2, 4, 6)
We find the probability by dividing the favorable results (3) by the # of all results (6).
3/6=1/2=0.5=50%

length = 15
let the width = w then length = 2w - 3
Perimeter = 2(length + width)
= 2(2w - 3 + w) = 2( 3w - 3) = 6w - 6 = 48
hence 6w = 48 + 6 = 54 ⇒ w == 9
Thus length = 2w - 3 = (2× 9) - 3 = 18 - 3 = 15
The solution to the equation is (b) there is no solution.
<h3>How to solve the rational equation?</h3>
The equation is given as:
Factorize the quadratic numerator
Multiply through by (x - 1)(x - 2)
2x(x - 2) - (2x -5) = -3(x - 1)
Expand
2x² - 4x - 2x + 5 = -3x + 3
Collect like terms
2x² - 4x - 2x + 3x + 5 - 3 = 0
Evaluate the like terms
2x² - 3x + 2 = 0
Using a graphical tool, the above equation has no real solution
Hence, the solution is (b) there is no solution.
