Answer:
$10,000
Step-by-step explanation:
Let b represent the amount invested in bonds. Then 50,000 - b wil be the amount invested in stocks. Molly's total return is ...
0.15b + 0.18(50000-b) = 8700
-0.03b +9000 = 8700 . . . . simplify
300 = 0.03b . . . . . . . . . . . . add .03b-8700
10,000 = b . . . . . . . . . . . . . divide by 0.03
Molly invested $10,000 in bonds.
Answer:
15 students study math and not English
Step-by-step explanation:
lets take the # or people who study math but not English as "x"
so 90 students study math or English
25 students study English and not math
and
50 study both
since 90 students study math or English that is what our equation will equal.
so
25+x+50=90
25+50=75
75+x=90
subtract "75" from both sides:
x=15
Hope this helps!

Now your going to distribute -4 and -3 which is 12.
So your simplified expression would be -16x + 12
