Which ordered pair (a, b) is a solution to the given system of linear equations?

3a+b=10
-4a-2b=2

(1, 7)
(3, 1)
(11, –23)
(23, –11)

Option C

Step-by-step explanation:

Given is a systems of equations in two variables a and b.

3a+b=10

-4a-2b=2

Let us solve this and find solution.

We can do this by elimination method

I equation x 2 gives    

Add these two equations to get

2a = 22

Divide by 2

We get a=11

Substitute in I equation

3(11)+B=10

b =10-33 =-23

Hence solution set is

(11,-23)

Option C is the right anser.

283 square feet

step-by-step explanation:

good luck

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
