4x -2(12x-1)= 14
4x-24x+2=14
-20x+2=14
-20x=12
x=-0.6 or -3/5
Answer:
You are a rectangular prism.
Step-by-step explanation:

Answer:
A
Step-by-step explanation:
We need to use some properties of an isosceles triangle and the Pythagorean Theorem.
First, the vertical line down the middle of the triangle is the height, which means the angle is makes with the base is 90 degrees and it bisects the base. So, we have two right triangles, each with a height of 6 and with a base of 4/2 = 2.
We can now use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 6 and b = 2 and x = c, so:
a² + b² = c²
6² + 2² = x²
x² = 36 + 4 = 40
x = √40
Thus, the answer is A.
Answer:
x/3 == 300
Marcy earned $900 last week.
Step-by-step explanation:
For this problem let's consider that 3 equal parts, or "split her income from last week equally" is 3 parts of her entire paycheck.
So she put $300 into savings which is x/3, if we let x represent the amount in dollars of her entire paycheck.
Then we can say the following:
If x / 3 == $300, then x == $900.
x / 3 == 300
( x / 3) * 3 == 300 * 3
( x * 3 / 3 ) == 300 * 3
x == 300 * 3
x == 900
So you can say the following:
x/3 == 300
Marcy earned $900 last week.
Cheers.

Explanation:
The take-home percent of the gross pay can be calculated with the following formula:
In this problem, we have
net pay = $2301.23
gross pay = $3984
If we substitute these numbers into the formula, we find
