Answer:
x = 4
Step-by-step explanation:
The absolute value of 5x is still 5x.
5x - 2 = 18
Add 2 to both sides
5x = 20
Divide both sides by 5
x = 4
Answer:
y = -5/2x - 13
Step-by-step explanation:
First, we have to find the slope of the original equation
Subtract 5x from both sides
5x + 2y = 1
- 5x - 5x
2y = -5x + 1
Divide both sides by 2
2y/2 = (-5x + 1)/2
y = -5/2x + 1/2
The slope of this equation is -5/2, so -5/2 has to be in our new parallel equation
y = -5/2x + b
Plug in the given x and y
-3 = -5/2(-2) + b
-3 = 10 + b
Subtract 10 from both sides
-3 = 10 + b
- 10 - 10
b = -13
This makes our equation: y = -5/2x - 13
Answer:
x = 3 or x = -3
Step-by-step explanation:
The absolute value of 3x = 9
Divide nine by 3 to get 3
Absolute value represents the number of spaces an integer is from 0, so the answer could also be -3, as the absolute value of 3 x -3 (-9) is 9.
Answer:
Step-by-step explanation:
Capacity of cylinder =4.25L
So volume of the cylinder=4250
πr^2h=4250
3.14×6.5×6.5×h=4250
132.665h=4250
h=4250/132.665
h=32.035
Answer:
2*2=4, 9*2=18, so 2/9 = 4/18, 4 students are Minton walkers.
