B = amount invested in B bonds
c = amount invested in CDs
so.. she's got $70000 burning a hole in her pocket and she wants to invest them to get a yield of 5000 in interest from both of them.
we know that, whatever "c" and "b" are, we know that
b + c = 70,000.
how much is 13% of b? well, (13/100) * b, or 0.13b
how much is 5% of c? well, (5/100) * a, or 0.05c
we know that, the yield or interest earned from them, must be 5000, thus
0.13b + 0.05c = 5000.

how much did she invest in CDs? well, c = 70000 - b.
Answer:
x=65
Step-by-step explanation:
solve for the angle not marked⇒ 180-147=33
add known angles⇒ 33+82= 115
subtract total known value from 180**⇒ 180-115=65
**all interior angles of a triangle must add up to 180°
Traveled hours by a in four years = 120
<span>Traveled hours by b in four years = (120/100) * 120
</span> = 144
Excessive hours traveled by b in 4 years = 144 - 120
= 24
<span>Excessive hours traveled by b in 1.5 years = (24/4) * 1.5
</span> = 9 hours
