Answer:
Step-by-step explanation:
Let x represent the amount invested at 8%. Then the total interest earned is ...
0.06(7000 -x) +0.08x = 480
420 +0.02x = 480 . . . . . . . . . eliminate parentheses
0.02x = 60 . . . . . . . . . . subtract 420
x = 60/0.02 = 3000 . . . . . divide by the coefficient of x
$3000 was invested at 8%; $4000 was invested at 6%.
Measure angle JKC + measure angle CKL = measure angle JKL
measure angle JKL = 122 and measure angle CKL = 74
Substitute wuth these values in the equation to get measure angle JKC where:
JKC + 74 = 122
measure angle JKC = 122 - 74
I think u would just do the work and add the decimal in
