For #6

x + y = -10
x - y = 2

First solve for y in one of the equations

x - y = 2
-y = 2 - x
y = -2 + x
y = x - 2

Now substitute into one of the equations and solve for x

x + y = -10
x + x - 2 = -10
2x - 2 = -10
2x = -8
x = -4

The sales tax on a $20 hammer is 7 percent, or $1.40. why is this tax a bigger burden for josh, who has a $15,000 income, than f

Bond [772]

Answer:

The ratio of the sales tax to Josh income is greater than the sales tax to aaron income (As the income of the Josh is less as compared to the arron income) this shows the tax is bigger burden for the Josh as compared to the aaron .

Step-by-step explanation:

As given

The sales tax on a $20 hammer is 7 percent, or $1.40.

As income of the josh is 15000 and the income of the aaron is $150000 .

Now the ratio of the sales tax to the josh income .

$\frac{Sales\ tax}{Josh\ income} = \frac{1.40}{15000}$

$\frac{Sales\ tax}{Josh\ income} = \frac{14}{15000\times 10}$

$\frac{Sales\ tax}{Josh\ income} = \frac{7}{75000}$

In decimal form

$\frac{Sales\ tax}{Josh\ income} = 0.000093\ (Approx)$

Now the ratio of the sales tax to the aaron income .

$\frac{Sales\ tax}{aaron\ income} = \frac{1.40}{150000}$

$\frac{Sales\ tax}{aaron\ income} = \frac{14}{150000\times 10}$

$\frac{Sales\ tax}{aaron\ income} = \frac{7}{750000}$

In decimal form

$\frac{Sales\ tax}{aaron\ income} = 0.0000093\ (Approx)$

Thus as the ratio of the sales tax to Josh income is greater than the sales tax to aaron income (As the income of the Josh is less as compared to the arron income) this shows the tax is bigger burden for the Josh as compared to the aaron .

A survey of 100 people found that 35 people exercise in the morning, 45 people exercise in the afternoon, and 20 people exercise

Sophie [7]

Jim is correct because the ratios need to compare with the total amount of people surveyed. 55, 80, and 65 are numbers that don't fit in and don't tell the overall ratio. You can tell this by writing it as a fraction.
Ex: 35:100 = 35/100. This literally means 35 out of 100 people exercise in the morning.

Hope this helps! If you have any questions, just ask!
