False

The segments below could not form a triangle.

In this case, the Triangle Inequality Theorem is used. Basically, just add up the pairs:

9 and 7

9 and 16

7 and 16

Make sure when you add them up, the sum of the two sides is greater than the other side. Unfortunately, this is not true because 9 + 7 = 16. In order for this to have been true, the two sides would have had to equal a number greater than 16, not equal to.

Anji bought 4 shirts for $56.80. She later bought a shirt for $19.20. What was the mean cost of all the shirts in dollars?

MakcuM [25]

Answer:

$15.20

Step-by-step explanation:

When you are asked to find the mean, you would add up the costs of the shirts and then divide them by however many shirts she got.

56.80 + 19.20 = 76

76 ÷ 5 = 15.20

Thus the mean cost is $15.20

3(x+2)=−5−2(x−3)

tia_tia [17]

Answer:

x = -1

Step-by-step explanation:

3(x+2)=−5−2(x−3) multiply 3 and -2 with inside the parenthesis

3x + 6 = -5 -2x + 6 now add the like terms

3x + 2x = 1 - 6

5x = -5 simplify both sides

x = -1
