Answer:
![x = 18](https://tex.z-dn.net/?f=x%20%3D%2018)
Step-by-step explanation:
Given
![\frac{x}{6} - 7 = -4](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%7D%20-%207%20%3D%20-4)
Required
Solve for x
![\frac{x}{6} - 7 = -4](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%7D%20-%207%20%3D%20-4)
Add 7 to both sides
![\frac{x}{6} - 7+7 = -4+7](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%7D%20-%207%2B7%20%3D%20-4%2B7)
![\frac{x}{6} = -4+7](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%7D%20%20%3D%20-4%2B7)
![\frac{x}{6} = 3](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%7D%20%20%3D%203)
Multiply through by 6
![6 * \frac{x}{6} = 3 * 6](https://tex.z-dn.net/?f=6%20%2A%20%5Cfrac%7Bx%7D%7B6%7D%20%20%3D%203%20%2A%206)
![x = 3 * 6](https://tex.z-dn.net/?f=x%20%3D%203%20%2A%206)
![x = 18](https://tex.z-dn.net/?f=x%20%3D%2018)
Answer: X+10
X+10
Explanation:
Break down the information given to you to try and identify what the algebraic expression must looks like. You know that you're dealing with
a sum
→
this means that you are adding something, so you're going to use the
+
sign;
of a number
→
this means that you're dealing with a variable. The most common notation for a variable is
x
.
and 10
→
this is simply an integer that must appear in the algebraic expression along the variable
x
.
So, put all this together to get
x
+
10
You're adding an unknown number,
x
, to an integer,
10
Assuming it was an entire year so 12 months
12 x 13 = 156
289 x 0.07 = 20.23
156 + 20.23 = $176.23
Answer:
x = 7
Step-by-step explanation:
A line perpendicular to the x- axis is a vertical line parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line goes through
The line goes through (7, 13) with x- coordinate of 7, thus
x = 7 ← equation of perpendicular line
