Answer:

12.3 - 7.9x

Step-by-step explanation:

I added the numbers without variables first then I added the numbers with variables:

8.9+3.4 = 12.3

-1.4x + -6.5x = -7.9x

Answer:

x = 1.6

Step-by-step explanation:

Simplify the expression

8.9 – 1.4x + (–6.5x) + 3.4

8.9 - 1.4x + (-6.5x) + 3.4

collect like terms

8.9 + 3.4 - 1.4x - 6.5x

12.3  - 7.9 x = 0

take 7.9x to the left side

12.3 = 7.9x

divide both sides by 7.9

x = 12.3/7.9

x = 1.55696202532

x = 1.6

Which function is undefined when theta=pi/2 radians?
Verizon [17]
We know that tanθ = sinθ/cosθ

For a number to be undefined, the denominator must equal to 0. At π/2, the cosθ value is 0 and sinθ is 1. Hence, tan(π/2) is undefined. 

Hope I helped :)

Cost of an oil change: $18.00; Markup: 3/4 answers
hjlf
I am assuming that the cost of an oil change already includes the mark-up.

So, 18 is 175%.  18 ÷ 1.75 = 10.29 is the original cost.

10.29 * 3/4 = 30.87/4 = 7.71 mark-up
10.29 + 7.71 = 18

Or if 18 is the basis of the mark-up, then,

18 * 3/4 = 54/4 = 13.50 mark-up
18 + 13.50 = 31.50 new cost of an oil change
