Please i need help whats 1/5x - 2 = 4

Orlov [11]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

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

Add sides 2

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

$\frac{1}{5} x = 6 \\$

Multiply sides by 5

$5 \times \frac{1}{5} x = 5 \times 6 \\$

$x = 30$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

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

Add sides 2

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

$\frac{1}{5x} = 6 \\$

Inverse both sides

$5x = \frac{1}{6} \\$

Divide sides by 5

$\frac{5x}{5} = \frac{1}{6} \div 5 \\$

$x = \frac{1}{6} \times \frac{1}{5} \\$

$x = \frac{1}{30} \\$

We're not supposed to help with exams. This isn't an exam, is it?

A(0)=202, A(37)=half that.

$A(t) = 202 (\frac 1 2)^{t/37}$

$A(100) = 202 (\frac 1 2)^{100/37} \approx 31.0$

Last choice.

if you were pouring juice into a cylindrical cup with a 2 inch radius and height of 8 inches. you want to fill it exactly half f

balandron [24]

Answer:

You would pour 50.3 in^3 of juice

Step-by-step explanation:

The term ‘cubic’ indicates volume

so in the context of this question, we are to calculate the volume of the cylinder, then we divide by 2

Mathematically, we have the volume of the cylinder as;

V = pi * r^2 * h

r = 2 inch

h = 8 inch

Since we are dividing the volume by 2 (exactly half full)

V = 1/2 * pi * 2^2 * 8

V = 50.3 in^3
