Answer:

Joel earns $35.00 commission and the store keeps $715.

Step-by-step explanation:

You need to figure 5% of what he sold - or 5% of $750.

Of course, you can use a calculator, or multiply $750 by .05. I prefer to think of 10 percent ($75.00) and half that to get 5%. $35.00.

Joel earns $35.00 on the sale. Not bad!

If he gets to keep $35, deduct this from the price to find out how much the store will keep.

$750 - $35 - $715.

Which of the following best describes the solution to the system of equations below?
OverLord2011 [107]

Answer: OPTION A

Step-by-step explanation:

The equation of the line in slope-intercept form is:

y=mx+b

Where m is the slope and b the y-intercept.

Solve for y from each equation:

\left \{ {{5y=-4x+7} \atop {10y=-8x+14}} \right.\\\\\left \{ {{y=\frac{-4}{5}x+\frac{7}{5}} \atop {y=\frac{-8}{10}x+\frac{14}{10}}} \right.\\\\\left \{ {{y=\frac{-4}{5}x+\frac{7}{5}} \atop {y=\frac{-4}{5}x+\frac{7}{5}}} \right.

As you can see the slope and the y-intercept of each equation are equal, this means that both are the exact same line. Therefore, you can conclude that the system has infinitely many solutions.

Marcia bought a bag of red white and blue balloons for the party there were 49 balloons in the bag if there are twice as many re
DedPeter [7]

Answer:

Red color= 28 balloon

Blue color= 14 balloon

White color= 7 balloon

Step-by-step explanation:

Given: There are 49 balloons

As given, there are 2 red balloon equal to the number of blue balloon

∴ 2 red= blue\ balloon

Again given, there are 1/2 white balloon equal to the number of blue balloon.

∴ \frac{1}{2} \ white= blue\ balloon

As above equation, we can understand that:

2\ red= \frac{1}{2} \ white\ balloon

multiplying both side by 2

⇒ 4\ red= white\ balloon

which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.

∴ Total combination of all color of balloon= 2+4+1= 7

Now, checking how many number of times combination can we have in 49 balloon.

\frac{49}{7}= 7 \ times

Next, finding number of balloon in each color.

Red color= 4\times 7= 28\ balloon

Blues color= 2\times 7= 14\ balloon

White color= 1\times 7= 7\ balloon
