Answer: (7,5) X=7 and Y=5

Explanation:

Add the two equations together to eliminate y from the system.

x-y=2 + x+y=12
= 2x = 14

Divide both sides by 2

x=7

Substitute the value found for x into one of the original equations to solve for y

(7)-y=2

Move all terms to one side to make it easier

-y=2-7

Subtract

y=5

3/4 picked apples. If 120 students picked apples, how many picked bananas
Oxana [17]

Answer:

40 students picked bananas

Step-by-step explanation:

3/4 picked apples    

1 - 3/4 = 1/4 picked bananas

3/4x = 120

Multiply both sides of the equation by 4/3

4/3 * (3/4x) = 120/1 * (4/3)

x = 480/3

x = 160

                                               Total of 160 students

                                               /                                   \

                                   120 = apples                  160 - 120 = 40 = bananas

40 students picked bananas

Hope this helps :)

Beth has $300 In her savings account. she buys x shirts for $20 each. What is an inequality beth can use tp find how many shirts
Ber [7]
Let's see:

you do:

20 dollars x 10 = 200 dollars 
but 300 dollars - 200 dollars are exactly 100 dollars,
so if you want MORE than 100 dollars, then you do:

20 dollars x 9 = 180 dollars..
300 dollars - 180 dollars = 120 dollars

so your answer is:

she can buy 9 shirts
