You first divide 40 by 19:
19/40=?
Then you convert that to percentage by dropping the decimal point and attaching a %
(hint: you should get 48% about :)
Answer:
$18500 at 6% and $28500 at 8%
Step-by-step explanation:
Let x represent the amount invested at 6%. Then x+10000 is the amount invested at 8%. The total income from the two investments is the sum of the products of the amount invested and the interest rate:
x·6% +(x+10000)·8% = 3390
0.14x + 800 = 3390 . . . . . . . . collect terms
0.14x = 2590 . . . . . . . . . . . . . .subtract 800
2590/0.14 = x = 18500 . . . . . divide by the coefficient of x
Sue has invested $18500 at 6% and $28500 at 8%.
Answer:
5,526,447
Step-by-step explanation:
Create an equation where x is the third number.
837,451 + 879,837 + x = 7,243,735
1,717,288 + x = 7,243,735
x = 5,526,447
So, the third number is 5,526,447
75 degrees because we are asking what is -114-(-39) when we open the parenthesis we get -114+39 which is -75 so, we know -39 is 75 degrees warmer than -114
