Which of the following could not be a value of x? a -10 b-9 c-10.5 d-9.5

We know that sum of two sides in any triangle must be greater than the measure of third (longest) side otherwise triangle will not be formed.

According to picture longest side is 18

So this triangle must follow inequality

9+x>18

or 9-9+x>18-9

or x>9

that means value of x must be more than 9.

choices a, c, d are greater than 9 except choice b

Hence choice B-9 is the final answer.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
