Answer:

The answer is B) 1.

Step-by-step explanation:

Combine the equations like this:

2x+3y=\frac{2}{3}x-1

Then subtract 3y from all sides.

2x+3y-3y=\frac{2}{3}x-1-3y

Simplify the equation.

2x=\frac{2}{3}x-1-3y

Then subtract \frac{2}{3}x from all sides.

2x-\frac{2}{3}x=\frac{2}{3}x-1-3y-\frac{2}{3}x

Simplify again.

\frac{4}{3}x=-1-3y

Multiply all sides by 3.

3\times \frac{4}{3}x=-3\times 1-3 \times 3y

Simplify again.

4x=-3-9y

Divide all sides by 4

\frac{4x}{4}=- \frac{3}{4}- \frac{9y}{4}

Simplify again.

x= \mathbf{\frac{-3-9y}{4}}

Last year, an orange tree produced 36 oranges. This year, it produced fewer than 10. What are the possible values for how many f
weeeeeb [17]

Answer:

d : [ 0 , 26 ]

Step-by-step explanation:

Given:-

- The oranges produced last year, x = 36

- The oranges produced this year, y < 10

Find:-

What are the possible values for how many fewer oranges were produced from the tree this year

Solution:-

- The possible values for how many fewer oranges were produced this year relative to last can be determined by solving an inequality that signifies a difference (d) between last year and this year production as follows:

                                 d = x - y

                                 d = 36 - (<10)

- To remove the inequality from Right hand side we we can shift it to left hand side by inverting the inequality sig, since last production is exactly known we have:

                                d≥36 - 10

                                d≥ 26

- So the number of oranges produced are at least 26 less than last year and lower bound would be if there is no orange produced this year. Hence, the range is:

                               d : [ 0 , 26 ]
