Maria’s monthly bank statement showed the following deposits and withdrawals:
-$25.20, $52.75, -$22.04, -$8.50, $94.11
If Maria’s balance in the account was $47.86 at the beginning of the month, what was the account balance at the end of the month?
Please do a step by step explanation

Answer:
x = 35
Step-by-step explanation:
The angle marked 125° is angle DPE. The (vertical) angle formed from the rays opposite PD and PE is angle BPA. That angle is divided into two parts by ray PC. One of those parts is angle CPA, shown as 90°. The other part is angle CPB, shown as x°. This means ...
angle DPE = angle BPA . . . . vertical angles have the same measure
125° = 90° +x°
35 = x . . . . . . . . . . divide by °, subtract 90

what is a slope of (-20,-4), (-12, -10)
Answers
Answer:
Slope = -¾
Step-by-step explanation:
Given the points, (-20,-4) and (-12, -10), use the following formula to solve for the slope:
m = (y₂ - y₁)/(x₂ - x₁)
Let (x₁, y₁) = (-20,-4)
(x₂, y₂) = (-12, -10)
Substitute these values into the slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
[tex]m = \frac{-10 - (-4)}{-12 - (-20)}[/tex]
[tex]m = \frac{-10 + 4}{-12 + 20}[/tex]
[tex]m = \frac{-6}{8}[/tex]
Simplify the fraction into its lowest terms by dividing the numerator and the denominator by 2:
[tex]m = \frac{-6}{8}[/tex] ÷ [tex]\frac{2}{2}[/tex]
m = -¾
Therefore, the slope of the line is -¾

Step-by-step explanation:
2.5x+6=0.5x+46

2x=40
divide both sides by 2
x=20
Kardal used the line of best fit to predict that a man 80 inches tall would wear about a size 16 shoe. What can be concluded about this prediction? Check all that apply. The prediction is reasonable. The prediction is an interpolation. No data is given in the scatterplot for a height of 80 inches, but a shoe size can still be predicted. A prediction cannot be made for a man who is 80 inches tall. A man who is 80 inches tall will likely wear a size 12. 5 shoe.
Answers
Answer:
A and C
Step-by-step explanation:
A. The prediction is reasonable.
C. No data is given in the scatterplot for a height of 80 inches, but a shoe size can still be predicted.
__________________________________________________________
Based on the average height-to-shoe size ratio, it is rational to predict that a man who is 80 inches tall would wear a size 16 shoe, even without there being a scatterplot for a height of 80 inches.
