2x+3=5x-42 what is the number that belongs in the green box

1 answer:

8 0

Objective: Solve 2x + 3 = 5x - 42 for x.

Step 1: Subtract 3 from both sides.

2x + 3 = 5x - 42
2x = 5x - 45

Step 2: Subtract 5x from both sides.

2x = 5x - 45
-3x = -45

Step 4: Divide both sides by -3.

-3x = -45
x = 15

Answer:
x = 15

Function to inverse function f(x) =2x/3-17

ZanzabumX [31]

Answer:

Inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

Step-by-step explanation:

Given function is $f\left(x\right)=\frac{2}{3}x-17$ .

Now we need to find the inverse of the given function.

Step 1: replace f(x) with y

$y=\frac{2}{3}x-17$

Step 2: switch x and y

$x=\frac{2}{3}y-17$

Step 3: solve for y

$x=\frac{2}{3}y-17$

$x+17=\frac{2}{3}y$

$\frac{3}{2}(x+17)=y$

$\frac{3}{2}x+\frac{51}{2}=y$

Hence required inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

If about 25 babies are born every 5 seconds then how many babies are born in a minute, a hour, and a day?

anastassius [24]

5 = 25b
60 seconds / 5 = 12.
12 * 25 = 300.
300 babies / min
hr ? 300b * 60 min = 1800.
1800 babies/ hr.
1800* 24 = 43200 babies in one day.
