Answer:
Step-by-step explanation:
Let x represent the amount invested at 13%. Then (3x+199) is the amount invested at 12%. The total interest earned in 1 year is ...
(13%)(x) +(12%)(3x+199) = 1561.50
0.49x +23.88 = 1561.50 . . . . simplify
0.49x = 1537.62 . . . . . . . . . . subtract 23.88
x = 3138 . . . . . . . . . . . . . . . . divide by 0.49
3x+199 = 9613
$3138 was invested at 13%; $9613 was invested at 12%.
Answer:
Step-by-step explanation:
a/7+b
You simply have to use the values provided in the equation given. If a=49 and b=7 you have
49/7+7, since 49/7=7 you have
7+7 which equals
14
Answer:
Yes
Step-by-step explanation:
I've done this before.
As tgose lines are parallel then,
a = 140° ( by alternate interior angles)
then,
tha angle just below "a" on the other paralle line would also be 140° by corresponding angles,
using exterior angle property of triangle
66° + b = 140°
b = 140° -66
= 74°
