goldfiish [28.3K]

Answer:

C

Step-by-step explanation:

If Ricardo started studying at 4 p.m and for sure will not stop until after 7 p.m, that means that he will be studying for 3 hours at least, and maybe even longer. So the time he will spend studying is at least 3 hours.

Therefore, x>3, where x is the time Ricardo will spend studying.

In 2000, the total population of the U.S. was 281.4 million people. In 2010, it was 308.7 million people. What is the average ra
kifflom [539]

Answer:

2.73 million people per year

Step-by-step explanation:

Turn sentences into coordinates/points:

In 2000, 281.4 million people

  • (x₁, y₁) = (2000, 281.4)

In 2010, 308.7 million people

  • (x₂, y₂) = (2010, 308.7)

Rate of population per year:

\sf \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

\rightarrow \sf \dfrac{308.7-281.4}{2010-2000}

\rightarrow \sf 2.73 \ million \ people

Justin has $7.50 more than Eva, and Emma has $12 less than Justin. Together , they have a total of 63.00. How much money does ea
Setler [38]
Since no value is given to Eva, we'll call her x. Justin, then, is 7.50+x. That leaves Emma, who would be Justin (7.50+x) -12. If we add them all together we get 63. So our equation is

x + (7.50+x) + (7.50+x)-12 = 63

Combine like terms

x+x+x + 7.50+7.50-12 = 63
3x + 3 = 63
3x = 60
x = 20

Since we said Eva is x then Eva has 20 dollars.

Justin is 7.50 + x so 7.50+20=
$27.50

Emma is Justin - 12 so 27.50-12= $15.50

Let's check our answer...

15.50+27.50+20 = 63
63=63

It checks!
