Answer:
(14, -2)
Step-by-step explanation:
To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:
Now we know what <em>x</em> equals. Let's substitute this into the second equation:
We can then simplify:
Given equation
Combine y terms
Add 2
Divide by -11
So, we now know the value of y = -2.
To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:
Substitute for y
Distribute 8
Add 16
So, we now know the value of x = 14.
Therefore, we know a solution to the system of equations is (14, -2).
Answer:
Interest= $ 18.73
Step-by-step explanation:
Given : $600 at 9.5% for 120 days
To find : Find the interest due
Solution :
Simple interest formula
Principle(P)=$600 , rate(r)=9.5%=0.095 , time (t)= 120 days
In years, 1 year = 365 days
1 day = year
120 days = year
Put values in the formula
Therefore, Interest= $ 18.73
Length (L): 2w + 3
width (w): w
border (b):
Area (A) = (L + b) * (w + b) <em>NOTE: This is assuming the width also has a border</em>
= (2w + 3 + ) * (w +
