The formula to find the simple interest earned is
I = Prt
Solve for p by dividing both sides by rt to get
P=I/rt
P=?
I=20
R=0.05
T=5years
So
P=20÷(0.05×5)
P=80
Hope it helps!
Answer:
<u>65.</u>
Step-by-step explanation:
1. Write the expression.
2. Expand the expression.
![3x3x3x3 -[(-4)x(-4)]](https://tex.z-dn.net/?f=3x3x3x3%20-%5B%28-4%29x%28-4%29%5D)
3. Simplify.
![81 -[16]\\\\65.](https://tex.z-dn.net/?f=81%20-%5B16%5D%5C%5C%5C%5C65.)
Step-by-step explanation:
step 1. m: m is the variable, 1 is the coefficient, 1 is the degree, constant is 0.
step 2. 3t^2 +4t - 6: t is the variable, 3 and 4 are the coefficients, 2 is the degree, -6 is the constant.
step 3. 2 - h: h is the variable, -1 is the coefficient, 1 is the degree (highest variable exponent), the constant is 2.
step 4. -7a^2: a is the variable, -7 is the coefficient (before the variable), 2 is the degree, the constant is 0.
The answer is <span>2.25
You could multiply 0.5 by 72, then by 36, then by 18, and so on, until you found the 6th term.

35 students would not know any of the three languages, because if 30 know French, 19 knew German, and 16 knew Russian, that must mean that 65 students know at least one of the three languages. So you subtract 65 from 100 and end up with 35
