Sati [7]

Answer:

One month of gameplay costs $15

Step-by-step explanation:

Angie: 20 + 3x

Kenny: 20 + 2x

(20 + 3x) + (20 + 2x) = 115 --- add their costs together

(20 + 20) + (3x + 2x) = 115 --- collect like terms

40 + 5x = 115 --- simplify

5x = 75 --- subtract 40 from both sides

x = 15 --- divide both sides by 5

In scientific notation

mrs_skeptik [129]

$(3.9 \times {10}^{ - 3}) + 0.0026 =$

$(39 \times {10}^{ - 4}) + (26 \times {10}^{ - 4}) =$

$39 \times {10}^{ - 4} + 26 \times {10}^{ - 4} =$

$Factoring \: {10}^{ - 4}$

${10}^{ - 4} \times (39 + 26) =$

$65 \times {10}^{ - 4} = 6.5 \times {10}^{ - 3}$

Which expression is equivalent to -9(x – 4) – 6x?

kvv77 [185]

= -9(x – 4) – 6x
Multiply -9 by everything in parentheses first

= (-9*x) + (-9*-4) - 6x
= -9x + (36) - 6x

Combine like terms
= (-9x-6x) + 36

= -15x + 36

The middle choice is the answer:
-15x + 36

Hope this helps! :)
