Answer:

Lowest grade is 70.

Step-by-step explanation:

To have an average of 80 the total score is 4 * 80 = 320.

So the score for the next test must be  320  - (85 + 74 + 91)

= 70.

What is the value of y in the equation 4 + y = −3?<br><br> 7<br> 1<br> −1<br> −7
Natasha_Volkova [10]

Answer:

-7 is your answer

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.

4 + y = -3

Subtract 4 from both sides

4 (-4) + y = -3 (-4)

y = -3 - 4

y = -7

-7, or (D) is your answer
