Teresa earned scores of 88, 84, 88 points and 91 points on 4 test what is the lowest score she can get on the fifth test and sti
Usimov [2.4K]

Answer:

99 points

Step-by-step explanation:

Average of a data a is the sum of the data divided by the number of data.

Average = sum of data ÷ number of data

A = T/n .....1

For the average of 5 test to be 90.

The total sum of score must be;

Number of tests n = 5

Average A = 90

Substituting into equation 1

90 = T/5

T = 90×5 = 450 points

The total score must be equal to 450 point to have an average of 90 points

The sum of the first four test is;

88+84+88+91 = 351

Let x represent the first score,

351 + x = 450

x = 450 - 351

x = 99 points

The minimum score she can get in the fifth test is 99 points

Don't use math papa or anything like that, please. The best/Correct answer gets brainiac.
Solnce55 [7]

Answer:

y = -3/2x + 6

Step-by-step explanation:

We won't be able to figure out Y in number form, since we have a second variable, but we can figure it out in terms of X.

First, we have to subtract 6x from both sides

( -4y = -6x + 24 )

Then we have to divide both sides by -4

( y = -3/2x + 6 )

This is our final answer in terms of x
