There are 15 ice cream flavors and 3 different cone options, how many flavor combinations for double scoop cones are there? (a different order of flavors is a different cone and flavors can be repeated.)

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

22 dimes and 9 nickels

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
