Answer:
$ 2,600 was invested at 4% and $ 3,600 was invested at 9%.
Step-by-step explanation:
Given that in investing $ 6,200 of a couple's money, a financial planner put some of it into a savings account paying 4% annual simple interest, and the rest was invested in a riskier mini-mall development plan paying 9% annual simple interest, and the combined interest earned for the first year was $ 428, to determine how much money was invested at each rate, the following calculation must be performed:
3000 x 0.04 + 3200 x 0.09 = 408
2500 x 0.04 + 3700 x 0.09 = 433
2600 x 0.04 + 3600 x 0.09 = 428
Therefore, $ 2,600 was invested at 4% and $ 3,600 was invested at 9%.

I had this question on a recent test and got it right
Hope this helps! :)
x=8.9 because when you square it and divide you get 39.6.. rounded to 40.
Answer:
Wilson is 6 older than mary
w=6+m
wilson is 10 less than 5 times mary
w=-10+5m
w=5m-10
so now we set them eqal to each other since both equal w
m+6=w=5m-10
m+6=5m-10
minus m both sides
6=4m-10
add 10 to both sides
16=4m
divide both sides by 4
4=m
sub back
w=m+6
w=4+6
w=10
wilson=10
mary=4
the correct method is math
