Answer:
Step-by-step explanation:
We know that the sum of all the angles of a triangle add up to 180 degrees.
So, let's combine like terms:
7x + 3x + x = 11x
5 + 10 = 15
So, 11x + 15 = 180
We can rearrange the equation to look like this:
180 - 15 = 11x
180 - 15 = 165
So, 11x = 165
Then, divide:
165 / 11 = 15
So, x = 15.
Now we can find the measure of all the angles!
3x = 3 x 15 3 x 15 = 45.
7x + 5 = (7 x 15) + 5 7 x 15 = 105 105 + 5 = 110
x + 10 = 15 + 10 15 + 10 = 25
So, the angles are:
45 degrees
110 degrees
And 25 degrees
Answer:
$289.25
Step-by-step explanation:
First we should find out how much Ms. Maple would make in a week without overtime.
6.5 x 40 = 260
Now, let's figure out how much she makes per hour in overtime.
6.5 x 1.5 = 9.75
Now add up the hours of overtime.
9.75 x 3 = 29.25
Now we add the weekly wage to the overtime
260 + 29.25 = 289.25
For 40 hours of regular time at $6.50/hr and 3 hours of overtime at $9.75/hr, Ms. Maple will make $289.25 for the week.

Answer: x > 2
Step-by-step explanation:
First, you need to isolate the variable by subtracting each side by 15.
4x + 15 > 23
-15 -15
= 4x > 8
To get the value for the variable, divide each side by 4.
4x/4 = x 8/2 = 2
x>2
