After 5 tests Dara's average score was 88 what score must she average on the next two tests to have a seven-test average of 90?

Tomtit [17]

After 5 tests, her average was 88. To have a seven-test average of 90, the total must be:

$90 \times 7 = 630$

Her average after 5 tests was 88. Her total score on the 5 tests is:

$88 \times 5 = 440$

Subtract:

$630-440 = 190$

Find the average by dividing by 2:

$190 \div 2 = 95$

Her average must be 95

Please help! I have no idea what to do. I couldn't even guess an answer.

yulyashka [42]

y - y1 = m(x - x1)

Plug in:

Slope = m = 4

Point = (x1,y1) ----> (-3,7)

y - 7 = 4(x - -3) //Solve for y

y - 7 = 4(x + 3) //Answer

y - 7 = 4x + 12

y = 4x + 12 + 7

y = 4x + 19

Answer: B

jek_recluse [69]

The area of a square with a side of 8g^3h is:

$\bf{Area = 8g^3h \times 8g^3h}\\\\\bf{Area = (8g^3h)^2}\\\\\boxed{\bf{Area = 64g^6h^2}}}$
