Answer:

x = 6

Step-by-step explanation:

Alternate angles are congruent.

7x - 9 = 3x + 15               {Subtract 3x form both sides}

7x - 3x -9 = 15

      4x - 9=15            {Add 9 to both sides}

           4x = 15+9

           4x = 24

           x = 24/4

x = 6

An ice cream store sells 28 flavors of ice cream. Determine the number of 4 dip sundaes.
katrin [286]

Answer:

20,475\ ways

Step-by-step explanation:

we know that

<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

To calculate combinations, we will use the formula

C(n,r)=\frac{n!}{r!(n-r)!}

where

n represents the total number of items

r represents the number of items being chosen at a time.

In this problem

n=28\\r=4

substitute

C(28,4)=\frac{28!}{4!(28-4)!}\\\\C(28,4)=\frac{28!}{4!(24)!}

simplify

C(28,4)=\frac{(28)(27)(26)(25)(24!)}{4!(24)!}

C(28,4)=\frac{(28)(27)(26)(25)}{(4)(3)(2)(1)}

C(28,4)=20,475\ ways
