Serga [27]

Answer:

Emilio could estimate the answer by thinkinng of 50 as 100. Then 2/3 of 100 is 66.66666666. Divide this by 2 to get 33.33333333

Step-by-step explanation:

Hopefully this helps! I kind of just thought of what ran through my head so I would say it's an estimate.

Answer:

1. f(0) = 501170

2. decreasing

3. 2% decrease

4. 302438

Step-by-step explanation:

In 1995 x=0

f(x) = 501170(0.98)^0

f(0) = 501170

The population is decreasing since we are multiplying by .98 ^x

.98 is less than 1 so it is getting smaller each time.

1 -.98 = .02

It is decreasing by 2 % each year

2020-1995 =25 years

f(25) = 501170(0.98)^25

=302438.41862

Rounding to the nearest whole number

Answer and Step-by-step explanation:

The answer for this linear equation is : $x=\frac{22}{3}$

Let's Solve your equation step-by-step :

$x=\frac{22}{3}$

Step 1 : Simplify both the sides of the equation :

$\frac{x}{4}+\frac{x-5}{2}=3$

$\frac{x}{4}+\frac{1}{2}x+\frac{-5}{2}=3$ (By Distributing)

$\frac{1}{4}x+\frac{1}{2}x+\frac{-5}{2}=3$

$(\frac{1}{4}x+\frac{1}{2}x )+(\frac{-5}{2})=3$ (combining the like terms)

$\frac{3}{4}x+\frac{-5}{2}=3$

Step 2 : Add $\frac{5}{2}$ to both sides :

$\frac{3}{4}x +\frac{-5}{2}+\frac{5}2} =3+\frac{5}{2}$

$\frac{3}{4}x=\frac{11}{2}$

Step 3 : Now, multiply both the sides by $\frac{4}{3}$ :

$(\frac{4}{3})$ × $(\frac{3}{4}x)$ = $(\frac{4}{3})$ × $(\frac{11}{2})$

$x=\frac{22}{3}$

We've got our answer as : $x=\frac{22}{3}$
