Complementary angels add up to 90°
so x+18°=90°
so x=90-18=72°
Solve the first part of the equation
2.5 X 10 = 25
2.5 X - x = - 2.5x
+ 21
which all added together equals - 2.5x + 46
Now for the second part of the equation
- 3.5 X 3x = - 10.5x
- 3.5 X 20 = - 70
+ 84
which all added together gets you - 10.5x + 14
once you have both parts of the two sides solved, you have to start subtracting from each sides
- 2.5x + 46 = -10.5x + 14
- 46 + 46
- 2.5x = -10.5x + 60
-10.5x +10.5x
-13x = 60
60 ÷ -13x
x = -4.61
Answer:
y = 9
Step-by-step explanation:
x + y = 8
-1 + y = 8
y - 1 = 8
Add one to both sides to isolate y.
y = 9
Have a great day!
Answer: slope of the line is 1
Step-by-step explanation:
Slope of the line is calculated by
y2-y1/x2- x1
Locate the coordinates points:
(4, 7) and (5, 8)
X1 = 4; X2 = 5
Y1 = 7; Y2 = 8
Insert the values into the formula
Slope = 8 - 7/5 - 4
Slope = 1/1
Slope = 1
Answer:
So, Louis earns 12 dollars per hour.
To find the rate for Carl, we need to divide the money earned from the hours.
Carl earns 15 dollars per hour.
(a) Carl earns 15 dollars per hour.
(b) Carl earns more than Louis, because 15 > 12.
(c) In Picture
