Answer:
7%
Step-by-step explanation:
14+Sale tax=14.98
14.98-14=sale tax
14.98-14=0.98
0.98 is the sale tax now we need to find the percent
Let represent t percent
14 of t%=0.98
14*t/100=0.98
we need to use inverse operation to isolate T on one side so if its multiplication we need to do division on both sides to un-due multiplication.
So to move 100 we need to multiply on both sides and we will get
14*t=0.98*100
0.98*100=98
14*t=98
to move 14 we need to divide
14/14=1
we dont need to put 1t becuase t is =1
so we just write it as t
98/14=7
t=7
so Sale tax percent is 7%

Answer:
x=8
Step-by-step explanation:
Those angles are supplementary so:
140+5x=180
5x=40
x=8
57 + x + x + 130 = 167
57 + 2x + 130 = 167
187 + 2x = 167
- 187 - 187
---------------------------
2x = -20

2 2
x = -10
