Answer:
x = 11.4
Step-by-step explanation:
14.12 = 
( 3.6x - 12.8 )
Rewrite so that the equation is entirely in decimals;
14.12 = 0.5( 3.6x - 12.8 )
Distribute;
14.12 = 1.8x - 6.4
Inverse operations;
14.12 = 1.8x - 6.4
+6.4 +6.4
20.52 = 1.8x
/1.8 /1.8
11.4 = x
Answer:
x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.
Step-by-step explanation:
Let Lin works x hours per week.
Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.
And she has to work at least 5 hours a week to $175 per week.
So, the inequality that can be written from the above condition is x ≥ 5 .......(1)
And the equation that can be written that
8.25x + 10 = 175 ....... (2)
So now we can write x = 20 hours

Answer:
9.4 cm^3
Step-by-step explanation:
This figure is a cylinder so the formula is V=πr^2h
r is the radius and h is the height
Here we can see the height is 3 and the radius is 1
V=π(1)^2(3)
V=π3
V=9.42 (assuming π is 3.14)
Rounded to the nearest tenth is 9.4
Equation: 15 + 6t = 81
Work: 15 + 6t = 81
-15 -15
6t = 66
t = 11

Answer:
6
Step-by-step explanation:
You will recognize that these points both have the same x-coordinate, so are on the vertical line x=2. The distance between them will be the difference of the y-coordinates:
6 - 0 = 6
The points are 6 units apart.
__
If you like, you can use the distance formula.
d = √((x2 -x1)² +(y2 -y1)²)
The values of these parameters are ...
x1 = 2, y1 = 0
x2 = 2, y2 = 6
Then the distance is ...
d = √((2 -2)² +(6 -0)²) = √(0 +36) = 6
The distance between the points is 6 units.
