Answer: Step 1 box= 19 (2+3+4+5+5)
Step 2 box= 3.8 (19 divided by 5)
Step-by-step explanation:
You add together the numbers to get 19, the you divide the number by five because you added 5 numbers together.
You had it just right on the bottom. Your equation was perfect. It doesn't matter if you get a decimal number.
Your answers are right too, I double checked.
Hope I was helpful.
To do this problem you would first need to factor out a variable, which in this case I would want to do the first equation because it is isolated. Now the equations would look like this:
x = -2y - 1
4x - 4y = 20
Since we know that x is now equal to -2y - 1 we can plug it in to the x value in the second equation:
4 (-2y -1) - 4y = 20
-8y -4 - 4y
-12y - 4 = 20
-12y = 24
y = -2
Now that we know the y value plug the y value to one equation to find the x, I will be using the first equation
x + 2(-2) = -1
x - 4 = -1
x = 3
Solutions:
y = -2
x = 3
Answer:
65°
Step-by-step explanation:
x = 180 - 44 - (180-109) = 109 - 44 = 65°
Rectangle:
A = BH
= (18)(4)
= 72
Finding area of square:
72 = 2x
/2 /2
36 = x
Finding perimeter of square using area:
P = √a * 4
= √36 * 4
= 6 * 4
= 24
Therefore the perimeter of the square is 24 inches. I am not sure so sorry for any mistakes.
