3/4 + 2/3 = 17/12
7/8 - 2/3 = 5/24
3/5 x 1/3 = 1/5
4/7 x 2/3 = 8/21
If x + 4y = 6 and you subst. -x+3 for y, you get x + 4(-x+3) = 6.
Then x - 4x + 12 = 6, or -3x = -6, or x = 2. Since y = -x+3, here y = -(2)+3 = 1.
Thus, the solution to this system of linear equations is (2,1).
The answer to -6(x+3)=6 is x= -4
<u>Ashely have </u><u>56 ways</u><u> to choose from</u>
This question can be solved using a system in mathematics called Permutation and it's in a topic of mathematics called combinatorics.
<h3 /><h3>Permutation</h3>
This is the process of arranging a particular set of data in different ways.
Since Ashely is choosing 3 desserts out of 8 in no specific ways

Where n = total number of ways available
r = total numbers that would be selected.
Data given
Let's substitute these values into the equation.

From the calculation above, Ashley have 56 ways in which can choose 3 dessert from an 8 choice.
