Answer:
x = 45
x = 19
Step-by-step explanation:
A straight line = 180°
So,
12.
3x + x = 180
4x = 180
---- -----
4 4
x = 45
13.
(5x + 4) + (x - 2) + (3x + 7) = 180
Combine like terms:
(5x + 4) + (x - 2) + (3x + 7) = 180
9x + 4 - 2 + 7 = 180
9x + 9 = 180
-9 -9
------------------
9x = 171
----- -----
9 9
x = 19
Hope this helped.
2x + 90= 180
Because x is congruent to z, x=z
y is given as 90
x+y+z=180
2x + 90 = 180
The answer you be five. If you take the twenty tokens and divide them into groups of four, you will find that you are left with five groups of tokens. Each group of tokens represents an hour of parking time. This will give you five groups, or five hours, total.
B.) 23
the equation set up is “ 4x+13=105 “
do -13 on both sides which would then leave you with “ 4x=92 “. then you just divide 4x on both sides, giving you the answer of 23 :D
