Answer:
C
Step-by-step explanation:
∠ AFD = ∠ AFC + ∠ CFD
Given ∠ CFA = 90° and
∠ CFD = 90° - ∠ EFD, that is
∠ CFD = 90° - 62° = 28°, thus
∠ AFD = 90° + 28° = 118° → C
Answer:
option D
D. x = 5, y = 2
Step-by-step explanation:
Given in the question two equation,
Equation 1
5.3x + y = 28.5
Equation 2
4.2x + 3.1y = 27.2
rearrange equation 1 in terms of y
y = 28.5 - 5.3x
Substitute the value of y in equation 2
<h3>4.2x + 3.1(28.5 - 5.3x) = 27.2</h3>
4.2x + 88.35 - 16.43x = 27.2
4.2x - 16.43x = 27.2 - 88.35
-12.23x = -61.15
x = 61.15/12.23
x = 5
put value of x in any of the equation
<h3>5.3(5) + y = 28.5</h3>
y = 28.5 - 26.5
y = 2
C, because when you add 45 on both sides, and then after that when you have to subtract 15 in both sides, you get 0 = 120.
Rst you have to find the price of everything together
2 magazines for 9.95 each and a book for 14.95
9.95 + 9.95 + 14.95 = 34.85
Next you convert the percent to a decimal
6% = 0.06
Now you put a one in the ones place
1.06
Multiply this by the cost of everything
34.85 * 1.06 = 36.94
The answer is $36.94
Hope this helps!
