Answer:

1. $11.50 2a. 25 2b. Decrease by 10

Step-by-step explanation:

1. Let's write Marietta's wage before a raise as x

$12.25 = x + $0.75

$12.25 - $0.75 = x

x = $11.50

2a. Let's substitute p with the actual value ($170)

170 = 8n - 30

200 = 8n

n = 200/8 = 25

2b.

p = 8*25 - 40

p = 200 - 40 = 160

160 < 170 so the profit decreased

It decreased by 10 (170 - 160).

Which of the following is an example of an improper fraction? A. 6⁄7 B. 3⁄10 C. 4⁄5 D. 10⁄3

Natali [406]

Answer:

D. 10/3

Step-by-step explanation:

6/7 6 divided by 7 = 0.86

proper- doesn't go over 1

3/10 3 divided by 10 = 0.30

proper - doesn't go over 1

4/5 4 divided by 5 = 0.8

proper- doesn't go over 1

10/3 10 divided by 3 = 3.33

improper- goes over 1

PROPER- When divided, <u>DOESN'T</u> go over 1 whole

IMPROPER- When divided, <u>DOES </u>go over 1 whole

Which of the following equations has the same solutions as the equations 3x+2y=-12

Marianna [84]

B, C, E, F

<h2>Explanation:</h2>

In this problem, we have the following equation of a line written in Standard form:

$3x+2y=-12$

So we need to choose the equations that has the same solutions as this equation. If we multiply each equation by a constant term and find the same solution as the given equation, then they will have the same solution. This is only true fro options B, C, E and F.

Option B.

$-3x-2y= 12 \\ \\ Multiply \ both \ sides \ by \ -1: \\ \\ (-1)(-3x-2y)=(-1)(12) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option D.

$15x+10y= -60 \\ \\ Multiply \ both \ sides \ by \ 1/5: \\ \\ (\frac{1}{5})(15x+10y)=(\frac{1}{5})(-60) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option E.

$6x+2y= -12 \\ \\ Multiply \ both \ sides \ by \ 1/2: \\ \\ (\frac{1}{2})(6x+2y)=(\frac{1}{2})(-24) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option F.

$1.5x+y= -6 \\ \\ Multiply \ both \ sides \ by \ 2: \\ \\ (2)(1.5x+y)=(2)(-6) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

For the other options, there is no any constant term that multiplies both sides of the equation and gives us the same given equation.
