2 answers:

6 0

-9x - 2y = -20, x = 0

Plug in 0 for x.

-9(0) - 2y = -20

Simplify.

0 - 2y = -20

-2y = -20

Divide both sides by -2.

y = -20/-2

Simplify.

y = 10

substitute 0 for x in the equation.

-9(0) - 2y= -20

0 - 2y = -20

-2y= -20 (divide by -2)

y = 10

Shawna took a test that had a total of 20 items. She got 4/5 of the items correct. How many items did she get correct?

ehidna [41]

Shawna got 16 items correct

Step-by-step explanation:

To find the percentage of answers or part of total answers we multiply the fraction with the total number of items.

Given

Total items on test = 20

Correct items fraction = 4/5

Then,

$Correct\ items=\total\ items * \fraction\ of\ correct\ answers\\= 20 * \frac{4}{5}\\=\frac{80}{5}\\=16$
