Answer:

x=25

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(52)(x)−(4)(5)x1−125=0

25x+−20x+−125=0

(25x+−20x)+(−125)=0(Combine Like Terms)

5x+−125=0

5x−125=0

Step 2: Add 125 to both sides.

5x−125+125=0+125

5x=125

Step 3: Divide both sides by 5.

5x/5=125/5

x=25

Compare 1.6 square meters and 16 tenths square meters

Hatshy [7]

1.6 is more that 16 tenths because 16 tenths is written like 0.16, and if you take 1.6 and 0.16, you see that in the ones place 1.6 has 1 and 0.16 has 0, and 1 is bigger that 0. I hope that makes sense

If F(x)=x^3+5x and G(x) =2x+1, find F(5) + G(6)

schepotkina [342]

Answer:

$F(5)+G(6)=163$

Step-by-step explanation:

We were given that:

$F(x)=x^3+5x$ and $G(x)=2x+1$

When x=5

$F(5)=5^3+5*5$

$F(5)=125+25=150$

When x=6

$G(6)=2*6+1$

$G(6)=12+1=13$

This implies that:

$F(5)+G(6)=150+13=163$

Heeeeeeeeeeeelp 50 points

Viktor [21]

If X > 0 then X must be a positive number. If Y < 0 then Y must be negative. So the quadrant that contains Positive X values and negative Y values will contain the point that you are looking for. This would be the fourth quadrant.

Suppose the American Lung Association stated that approximately 1 out of every 20 deaths in the US last year was from lung cance

tester [92]

Answer: 10

Step-by-step explanation:

Given : The American Lung Association stated that approximately 1 out of every 20 deaths in the US last year was from lung cancer.

Then, the proportion of death will be :_

$p=\dfrac{1}{20}=0.05$

Now, If there are 200 students in a class, then the expected number of persons die from lung cancer :-

$p\times200\\\\=(0.050)\times200=10$

Hence, we expect the number of persons die from lung cancer =10
