Answer:
C. 9
Step-by-step explanation:
The measure of a triangle is 180.
Make all the angles equal 180.
50+80+6x-4=180.
Solve.
6x=54
x=9
I think it takes him about 9 minutes and 25 seconds to run a mile
Answer:
60
Step-by-step explanation:
ingressos: 55 x 2 = 110
25 x 2= 50 Tax
110+50=160 total
160-100= 60
Written in standard form, y decreased by 25 = 10 is y - 25 = 10
Now let's solve:
y - 25 = 10
y = 10 + 25
y = 35
to check:
35 - 25 = 10
so, y equals 35
For whatever they give you for x, you substitute that with the 2(x)+5
Ex. if the x was 3 it would be 2(3)+ 5 and then the answer would be 11 since 3 times 2 is 6 and then 6+5=11
