Answer:
D) the system has no solution.
Step-by-step explanation:
A student is solving a system of equations by substitution and comes up with the solution -3=2.
So, the unknown variables are canceled out and there are only numbers in the equation but -3 ≠ 2.
If we assume that she solved the problem correctly, then there will be no solution for that system of equations because there is no variable remaining in the final equation to solve for. (Answer)

Answer: 14 feet
Step-by-step explanation:
sin 30= 7/AB
1/2 = 7/AB

= 14
Answer:
The rate of simple interest is 25.89 %
Step-by-step explanation:
Given as :
The principal = $2350
The Amount = $2500
The time period = 90 days =
year = 0.2465 year
Let The rate of interest = R %
So, Interest = Amount - Principal
Or, Interest = $2500 - $2350 = $150
<u>From Simple Interest method </u>
Simple Interest = 
Or, $150 = 
or, $150 × 100 = $579.275 × Rate
So, Rate =
∴ Rate = 25.89 %
Hence The rate of simple interest is 25.89 % Answer
