Answer:
Step-by-step explanation:
Let x represent the amount invested at 9%. Then 7000-x was invested at 4% and the interest earned was ...
9%·x +4%(7000-x) = 430
5%·x +280 = 430 . . . . . . . . . simplify
0.05x = 150 . . . . . . . . . . . subtract 280
x = 3000 . . . . . . . . . . divide by 0.05
$3000 was invested at 9%; $4000 was invested at 4%.
Answer:
P= 2(3W + 7) + 2(W) = 110.
P= 6W + 14 + 2W = 110.
= 8W + 14 = 110.
= 8W = 110 - 14 = 96
W = 96/8 = 12- inches.
Now solve for (L) by L = 3W + 7 = 3(12) + 7 = 36 + 7 = 43- inches
7=43 inches if this help.can u mark me brainliest
