Answer:
m = 9
It means that you are multiplying each of the values inside the parentheses by 2.
Step-by-step explanation:
2(m + 2) = 22
2m + 4 = 22
2m + 4 - 4 = 22 - 4
2m = 18 -Divide both sides by 2
m = 9
Step-by-step explanation:
The expressions are not properly written
Given
RS = 4x – 9
ST = 19
RT = 8x – 14
Based on the given parameters, the addition postulate below is true
RS+ST = RT
Substitute
4x-9+19 = 8x-14
collect like terms
4x-8x = -14-19+9
-4x = -33+9
-4x = -24
x = -24/-4
x = 6
Get RS:
RS = 4x-9
RS = 4(6)- 9
RS = 24-9
RS = 15
Get RT:
RT = 8x - 14
RT = 8(6)-14
RT = 48-14
RT = 34
Finding the greatest common factor ( or G C F ):
G C F is the largest number that divides evenly into all the numbers.
270 : 90 = 3
360 : 90 = 4
G C F ( 270, 360 ) = 90
25-4x=16-4x
25-4x+4x=16-4x+4x
25=16
