Answer:
A. 4y + 3 = 15
B. y = 3
Step-by-step explanation:
Three is added to four times a number, the result is 15
A. Equation to represent the above information:
Let the unknown number= y
4 * y + 3 = 15
4y + 3 = 15
B. Solve your equation in (a)
4y + 3 = 15
Collect like terms
4y = 15 - 3
4y = 12
Divide both sides by 4
4y / 4 = 12 /4
y = 3
Therefore, the unknown number is 3
We could rewrite
2x + 3 = y
-4y + 8x = -12
as
2x - 1y = -3
8x - 4y = -12
We need to compare these two results. Do they represent the same equation or two different equations? Dividing the 2nd equation by 4 results in 2x - y = -3, which is indeed exactly the same as the first equation. Because of this, we have two straight lines that are superimposed; one lies right on top of the other. Thus, this system has an infinite number of solutions.
~Hello There!~
area of parallelogram = base x height
area = 9.2 x 3.8
area = 34.96cm^2
perimeter = 9.2 + 9.2 + 4.1 + 4.1
perimeter = 26.6cm
Hope This Helps You!
Good Luck :)
