What is the answer to
2x + 3y = 13
x = 2

Answers

Answer 1
Answer: \bf2x+3y=13

Plug in x = 2:

\bf2(2)+3y=13

Multiply:

\bf4+3y=13

Subtract 4 to both sides:

\bf3y=9

Divide 3 to both sides:

\bf~y=3

So our solution is \boxed{\bf(2,3)}
Answer 2
Answer:   2x + 3y = 13
2(2) + 3y = 13
    4 + 3y = 13
 - 4            - 4
          3y = 9
           3     3
           y = 3

Answers

Answer:

B. 1/4  

D. 1/3  

E. 1/8

Step-by-step explanation:

4/8 can be represented as 1/2 or a half, therefore, find fractions that are less than half of the denominator.

B.

Half of 4/4 is 2/4, 1/4 is less

D.

Half of 3/3 is 1.5/3, 1/3 is less

E.

Half of 8/8 is 4/8, 1/8 is less

Map pours 3 2/3 cup of orange juice into measuring cup from a large container then he poured 1 1/4 cups back into the container how much orange juice remains in the measuring cup

Answers

Answer:

2 5/12 cups

Step-by-step explanation:

Map pours 3 2/3 cup of orange juice into measuring cup from a large container then he poured 1 1/4 cups back into the container

The amount of juice remaining in the measuring cup is calculated as:

3 2/3 - 1 1/4

= 3 - 1 + ( 2/3 - 1/4)

LCD = Lowest Common Denominator is 12

= 2 + (4 × 2 - 3 × 1/12)

= 2 + (8 - 3/12)

= 2 + 5/12

= 2 5/12 cups

Hence, the amount of juice remaining in the measuring cup = 2 5/12 cups of juice
