Answer:
m = 10
Step-by-step explanation:
According to the picture attached, we can see the angles formed.
The angle on the top (5m+100) is sided with the angle 2m+10. This means that they are supplementary angles, their sum is 180°.
So,
5m+100+2m+10 = 180
5m+2m=180-100-10
7m = 70
m = 10
Answer:
The correct answer is x = -5
Step-by-step explanation:
All vertical lines can we written in terms of x = (a number). You can find this number in the ordered pair under the x-coordinate. In this case it is -5.
A number is :
_________________________________
Three quarters of it means :
_________________________________
Decrease by 20 means :
_________________________________
Equals to 82 means :
_________________________________
What is that number ?
x asked so we must solve the above equation for x.
Let's do it....
Plus sides 20
Multiply sides by 4
Divided sides by 3
Simplify
So that number is 136 .
