Tunde and Martha are married and share their income. Tunde earns $1,500 per year less than Martha. If their annual income is $47,500, how much does each earn?

Martha earns $24500 annually and Tunde earns $23000 annually.

Step-by-step explanation:

Let T represent Tunde income and M represent Marth income.

We know that if they add their income together it will be $47,500 so we could write that as and equation as  t + m = 47500  

It also shows us the relationship between the money that Tunde and Martha earn per year or annually. So if Tunde earns $1500 less than Martha every year then we could also represent it by the equation  t= m - 1500

Now we have two equations so we will solve them.

t + m = 47500

t= m-1500  substitute the value of t into the first equation.

m -1500 + m =47500   combine like terms.

2m = 49000

m= 24500

We now know that Martha earns 24500 per year so we will subtract is from the total fe to find how much Tunde earns.

47500 - 24500 = 23000

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
