Answer:
1%
Step-by-step explanation:
We use the simple interest equation of A=P(1+rt).
A-the total amount with interest earned
P-the initial amount or principal
r-rate
t-time in years
We substitute the values P=6900, A=6923, and t=0.33 since 4 months divided by 12 months is 0.333 years. We then solve for r.
Our final step is to divide both sides by 0.33.
This is the decimal of the rate. We convert to a percentage by multiplying by 100. 0.01(100)=1%.
You have to look for -3 on the x axis, and then proceed vertically (in this case upwards) until you meet the graph.
We land about 1/2 square above the 12 mark on the y axis. Since one square is 1/2 unit, a half square would be 1/4 unit.
So, we can estimate 
Answer:
47 - 2n
Step-by-step explanation:
An algebraic expression is an idea of representing numbers using letters or alphabet.
From the question above,
The variable = n
twice the number = 2× n = 2n
Translating:
47 - 2n
I dont understand wouldn't twice the number of 9 be 18 or 11?
9+2=11 or 9×2=18
