Use the elimination method to solve the system of equations. choose the correct ordered pair

Option B

Step-by-step explanation:

We have to solve the equation by elimination method equations are

5x + 3y = 31 (1)

2x + 3y = 25 (2)

Now we subtract equation (1) from (2)

( 5x + 3y ) - ( 2x + 3y ) = 31 - 25

( 5x - 2x ) + ( 3y - 3y ) = 6

3x = 6

x = 2

Now we put x = 2 in equation (1)

5 × 2 + 3y = 31

10 + 3y = 31

3y = 31 -10

3y = 21

y = 7

Solution is ( 2, 7 )

Therefore, Option B is the answer.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

1/2*qr*rs
