Answer:
39
Step-by-step explanation:
you need to work backwards
86-2-6=78
therefore, 78 = 2y
y = 2y/2, so 78/2 = 39

Answer: x - 2
<u>Step-by-step explanation:</u>
HCF is more commonly referred to as GCF (greatest common factor)
Factor each expression to see which factor(s) they have in common.
The only factor that all three expressions have in common is: x - 2
Answer:
A) y=400x+60,000 (really no work needed)
B) 67,200 volumes
C) 50 months after March 2004
Step-by-step explanation:
B) you will find the # of months between march of 2004 and september 2005, which would be 18 months (you exclude march of 2004) and substitute that number in for x in the first equation.
C) Instead of substituting in for x, we will substitute in for Y, so the equation will look like
80,000=400x + 60,000
and you would simplify this by isolating x, meaning that your answer will be 50, so you could say 50 months after march or you could actually find out the date.
5(3) + 1/2(2)^2 - replace variables with parenthesis that contain the variable's amount.
15 + 1/2(4) - parenthesis/exponents, multiplication.
15 + 2 - addition left to right.
17. - final answer.
Remember PEMDAS, your answer will be 17.
Now that you know how to solve it, don't copy paste this post.
You'll get caught, I promise.
Now that you know PEMDAS, make an explanation.
Good luck.
