correct answer is (c)
Step-by-step explanation:
(a) Total no. of marbles=3+2+4=9
(1) No. of white marbles=2
∴ probability of getting a white marble=
9
2
(2) No. of blue marbles=3
∴ probability of getting a blue marble=
9
3
=
3

(3) No. of red marbles=4
∴ probability of getting a red marble=
9
4
I'm not sure abt this answer, sorry if I get it wrong

Distribute 5 to all monomials inside the parenthesis
5(m + 4) = 5m + 20
5m + 20 = 2m + 20
Isolate the m, subtract 2m from both sides, and 20 from both sides
5m (-2m) + 20 (-20) = 2m (-2m) + 20 (-20)
5m - 2m = 20 - 20
Simplify
3m = 0
isolate the m, divide 3 from both sides
3m/3 = 0/3
m = 0/3
m = 0
hope this helps
Answer:
d. 24,000 at 3% and 8,000 at 5.5%
Step-by-step explanation:
Let the principal for the 3% loan be and that for the 5.5% loan be . Let their respective interests be and .
Then
From the question, the sum of the interests is 4640.
Also, the total amount borrowed is 32000.
To solve the last two equations simultaneously, multiply the second by 0.12 and subtract from the first (this eliminates ).
From ,
Hence, $24,000 was borrowed at 3% and $8,000 was borrowed at 5.5%.
