fredd [130]2 years ago

7 0

Answer:

Step-by-step explanation:

You can just check the values:

A. x = 2, y = 8

x + 3y = 2 + 3×8 = 26 not <16 ⇒ NOT these values

B. x = 9, y = 2

x + 3y = 9 + 3×2 = 15 <16

x + y = 9 + 2 = 11 >10

YES, x = 9, y = 2 are solutions of the system of inequalities

C. x = 1, y = 5

x + 3y = 1 + 3×5 = 16 not <16 ⇒ NOT these values

D. x = 7, y = 2

x + 3y = 7 + 3×2 = 13 <16

x + y = 7 + 2 = 9 not >10 ⇒ NOT these values

Evaluate each expression for g = -7 and h = 3 and match it to its value. 1. g + h 2 2. g - h 46 3. h - g -21 4. gh -4 5. g + h2

Ivanshal [37]

Answer:

1. -4

2. -10

3. 13

4. -21

5. 2

6. 46

Step-by-step explanation:

To evaluate the expression, substitute g= -7 and h = 3. Then simplify using order of operations.

1. $g-h = -7 + 3 = -4$

2. $g-h = -7 - 3 = -10$

3. $h-g = 3 - -7 = 3+10 = 13$

4. $gh = -7(3) = -21$

5. $g+h^2 = -7 + 3^2 = -7+9 = 2$

6. $g^2-h = (-7)^2 -3 = 49 -3 = 46$

PLEASEEEEE HELPPPP MEEEE!!!! There are 5 friends who decide to split an 88- ounce bag of popcorn. If they split it evenly, how m

timurjin [86]

Answer:

17.6 ounces (U.S.) and or 2.2 cups (U.S.)

Step-by-step explanation:

88 ounces divided by 5 equals 17.6 ounces

88 / 5 = 17.6

The remainder can round the answer to 18 (five or more raise the score -- four or less let it rest) but the 88 ounce bag of popcorn will not be even if everyone gets 18 ounces of popcorn

If everyone were to get 18 then the bag a popcorn would have to have 90 ounces of popcorn in it

*Side note: 8 ounces is 1 cup
