Answer:
She added 83 instead of subtracting
Step-by-step explanation:
83 + n = 110
We want to do the opposite to n
We are adding 83 to n. The opposite is subtract 83
83+n-83 = 110-83
n =27
Mia
83 + n = 110
83 + 83 + n = 110 + 83
163+n=193
Answer:
m<2 = 57
Step-by-step explanation:
Since they are all in a straight line, the sum of the three angles = 180
Let m ∠3 = x
Thus;
2m<1 = x - 6
m<1 = (x-6)/2
m<2 = x-27
Adding all
x + x-27 + (x-6)/2 = 180
Multiply through by 2
2x + 2x -54 + x -6 = 360
5x -60 = 360
5x = 360 + 60
5x = 420
x = 420/5
x = 84
But m<2 = x -27
m<2 = 84 -27 = 57
Here is the method for solving that equation:
Step #1: Write the equation:
-15x = 0
Step #2: Divide each side of the equation by -15 :
<u>x = 0</u>
Answer:
(0,-22)
Step-by-step explanation:
Answer:
4x + 7 = 3
Step-by-step explanation:
let the number be x
4 times x = 4x
sum of 4x and 7 = 4x + 7
Sum of 4x + 7 is 3 becomes;
4x + 7 = 3
