Answer:
x = -5 and y = 8
Step-by-step explanation:
To solve the system by substitution, solve one equation for a variable. Then substitute the equation into the other equation.
x + 2y = 11 becomes x = 11 - 2y
Substitute x = 11 -2y into 4x + 4y = 12.
4(11-2y) + 4y = 12
44 - 8y + 4y = 12
44 - 4y = 12
32 = 4y
y = 8
Substitute again with y = 8 into the equation to find x.
x = 11 - 2(8)
x = 11 - 16
x = -5

Answer:
CPCTC
Step-by-step explanation:
The applicable reason for statement 4 is "Corresponding Parts of Congruent Triangles are Congruent (CPCTC)".
The reason shown in your problem statement is applicable only within one triangle. The segments of interest are in two different triangles.
Answer:
<u>1.</u> 20 boxes cost $36. The unit rate is 1:1.8 and when you multiply 1.8 by 5 you get 9. If you also multiply 1.8 by 20 you get 36.
<u>2.</u>He completes 12.5 pages in 200 minutes.
200 divided by 32
multiply that answer by 2
which is 12.5.
hope it helps!
Equation: 45000(1+.1)^6
Answer: 79720.25
Explanation:
This is a prime example of a Compound Interest Formula based question. Due to the fact the question states that the woman is getting a raise every year, we add one rather than subtracting one. Next we convert the 10% into a decimal form into 0.1 and from there since the time is all the same we wouldn’t need to divide anything out so we raise the equation to the sixth power and our final answer is $79720.25
