Answer:

The score on the next test must be between 86 and 98, inclusive

Step-by-step explanation:

Write an inequality using the average:

86 ≤ \frac{83+89+x}{3} ≤ 90

Solve for x:

multiply everything by 3:

258 ≤ x + 83 + 89 ≤ 270

258 ≤ x + 172 ≤ 270

subtract 172 from everything:

86 ≤ x  ≤ 98

The score on the next test must be between 86 and 98, inclusive

4x + 6y = 18 & 4x – 2y = 10
kherson [118]

Answer:

x=4.875

y=-0.25

Step-by-step explanation:

4x – 2y = 10

2x-y=10

y=2x-10

4x + 6y = 18

2x+3(2x-10)=9

8x=39

x=4.875

y=2(4.875)-10

y=-0.25

Determine whether the variation between the indicated quantities is direct or inverse. The number of calories in a cheese pizza
-BARSIC- [3]

Answer:

The variance is direct.

Step-by-step explanation:

Since size of the pizza determines the amount of calories.

Let us say that a 2" x4" strip of pizza has 250 calories.

Then a pizza of twice the size (or 4" x 4") will have twice as many calories (500 calories) .
