We have to use the Distributive Property in this equation.
By the Distributive Property,
becomes
Now we need to isolate x. Remember PEMDAS?
Simplify the right side.
Answer:
20%
Step-by-step explanation:
400/2000=0.2
0.2*100=20
Answer:
y = -3x + 1
Step-by-step explanation:
slope = -3
y = mx + b
7 = -3(-2) + b
7 = 6 + b
1 = b
y = -3x + 1
Using simple interest, it is found that $13,872 was loaned at 9%.
<h3>Simple Interest</h3>
The amount of money after t years in simple interest is modeled by:
In which:
- r is the interest rate, as a decimal.
The interest earned is:
A bank loaned out $14000, in two parts, hence:
Part of it at the rate of 9% per year and the rest at 17% per year, hence:
The interest received in one year totaled $2000, hence:
Then:
Isolating 
as a function of 
, then we can replace on the equation for the first interest.
Then:
$13,872 was loaned at 9%.

Answer:
Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn't on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale.
Step-by-step explanation:
