We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years
In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
Answer:
I think it is A, or ,D
Step-by-step explanation:
Answer:
p= 6q+7
-7. -7
p-7 =6q
/6. /6
p-7/6
Step-by-step explanation:
if you want to make a specific term the subject, you need to isolate it on one side of the equation. You do this by 'getting rid' of anything on the term's side of the equation, starting with whatever's furthest from the term. (think BEMDAS but backwards)
p = 6q + 7
(take 7 from both sides to get rid of +7 on q's side)
p - 7 = 6q + 7 - 7
p - 7 = 6q(divide both sides by 6 to get rid of 6 on q's side)
=
q=
Answer:
3x3-45÷(4+1) is 0.
Step-by-step explanation:
We have to do order of operations so we follow PEMDAS:
P is for Parentheses so we do what's in parentheses first:
(4+1)=5
E is for Exponents but we don't have exponents.
Next is M and D for Multiplication and Division. We have division before multiplication so we should do division first:
45÷5=9
We now have multiplication:
3x3=9
Now we have A and S for addition and subtraction
We don't have addition so we'll do subtraction:
9-9=0
The final answer is 0.
Hope this helps! :)
