im not sure if this answer is correct but i think its 22
<em>Answer:</em>
( B ) x = 6.5
<em>Step-by-step explanation:</em>
We know that all the angles of a triangle equal 180 when added together. So lets make an equation for this question.
(10x-10) + (10x+8) + 8x = 180
I just took all the angles and added them together to make 180. Now solve for x.
10x - 10 + 10x + 8 + 8x = 180 <em>(combined like terms)</em>
28x -2 = 180 <em>(added 2 to both sides)</em>
28x = 182 <em>(divided both sides by 28)</em>
x = 6.5
Answer:
This is the value in numbers.
5(n-12)>40
Step-by-step explanation:
Let's solve your inequality step-by-step.
5(n−12)>40
Step 1: Simplify both sides of the inequality.
5n−60>40
Step 2: Add 60 to both sides.
5n−60+60>40+60
5n>100
Step 3: Divide both sides by 5.
5n

n>20
Answer:
n>20
This is the same as any math problem you may have solved before.
First, start by isolating the x on one side. I will choose to keep the coefficient positive, so I will add x to both sides.
6>2x+2
Subtract 2
4>2x
Divide by 2
2>x
Or
x<2
