First, move like terms on one side. Next, add them and divide. See the attachment for solution.
Answer:
Step-by-step explanation:
First, subtract 180 and "12x-3", which equals 180-12x+3
Then add 46, "5x+7", and "180-12x+3"
46+5x+7+180-12x+3 = 180
Since the degrees in a triangle add up to 180 degrees, cancel out the 180 degrees from this side "180-12x+3" and the other side "180"
46+5x+7-12x+3=0
46+10-7x=0
56=7x
X = 8
Answer:
(a)
(b)$3763.31
Step-by-step explanation:
When a Principal, P is invested at an annual rate r, for a period of k times over n years, the Amount, A(t) after n years is given by the model:
In this case:
r=1.8%
Since it is compounded bimonthly, k=2X12=24
Therefore:
For P=$2400, and n=25 years
The balance in the account after 25 years is $3763.31.
Answer:
what´s the question????
Step-by-step explanation:
20 picks in all because
3/5 = 12/x
3x4 = 12
5x4 = 20
