If it is #17 this:
the class sold 45 sandwiches and collected $150.75, all you need to do is divide.
150.75/45
= 3.35
$3.35 per sandwitch
Divide both sides by -5
Sqrt(x) = 3
We want to isolate x to solve for it. The opposite of a square root is a square, so square both sides.
x = 9
It can't be -9 because the square root of negative numbers are not real numbers.
Answer:
p = q
Step-by-step explanation:
Angles in a triangle add up to 180°
For the left triangle:
180 = p + 20 + 80
p = 80
For the right triangle:
180 = q + 45 + 55
q = 80
Therefore, p = q
(18-7x)+1= -9 Hope this helps ^^
Answer:
317,988,000
Step-by-step explanation:
We have been given that according to the United States Census Bureau, on September 11, 2014, the population of the United States was increasing by 11 people every 12 seconds.
Let us find number of people increased in 1 minute as:

Now, we will convert 11 years into minutes and multiply by 55 to find increase in population in 11 years.



Upon multiplying 5,781,600 by 55, we will get:


Therefore, the population of United States would increase 317,988,000 in 11 years.
