To use the equation we need a1 and d(the common difference).
We have a1 = 57, we need to find d.
93-84 = 9; 84-75=9; 75-66=9; 66-57=9
d = 9
a350 = 57 + (350-1)(9)
a350 = 57 + (349)(9)
a350 = 57 + 3141
a350 = 3198

Answer:
Step-by-step explanation:
Let x and y represent amounts invested at 6% and 9%, respectively.
y = 3x +58 . . . . . . . the amount invested at 9%
0.06x +0.09y = 1097.19 . . . . . . total interest earned
__
Substituting for y, we have ...
0.06x +0.09(3x +58) = 1097.19
0.33x + 5.22 = 1097.19 . . . . . . . . . simplify
0.33x = 1091.97 . . . . . . . . . . . . subtract 5.22
x = 3309 . . . . . . . . . . . . . . . . divide by 0.33
y = 3(3309) +58 = 9985
$3309 is invested at 6%; $9985 is invested at 9%.
Answer:
A.
Step-by-step explanation:
12.5/10=1.25.
12.5/8=1.56
12.5/12=1.04
12.5/6=2.08
it's important to know what 1/2 is, 1/3 is, 1/4 is and 1/5 it's also important to know things like 2/2, 2/3, 3/3, 2/4, 3/4, 4/4, 2/5, 3/5, 4/5, and 5/5. You don't need this until 8th grade though. But get on it if you can. Ask your parents or teacher.
