\frac{1}{8} (x + 24) =  \frac{5}{8} x + 9 -  \frac{1}{2} x \\ \\  \frac{x + 24}{8} =  \frac{5}{8} x + 9 -  \frac{1}{2} x \ / \ simplify \\ \\  \frac{x + 24}{8} =  \frac{5x}{8} + 9 - \frac{1}{2} x \ / \ simplify \\ \\  \frac{x+ 24}{8} =  \frac{5x}{8} + 9 -  \frac{x}{2} \ / \ simplify \\ \\  \frac{x + 24}{8} =  \frac{x}{8} + 9 \ / \ simplify \\ \\ x + 24 = x + 72 \ / \ multiply \ each \ side \ by \ 8 \\ \\ 24 = 72 \ / \ cancel \ x \\ \\ no \ solution \\ \\

The final result is: no solution.

1/8(x+24)=5/8x+9-1/2x
1/8x + 3 = 5/8x - 4/8x + 9
1/8x + 3 = 1/8x + 9
3 ≠ 9

This equation has 0 solutions, or NO solution.

For each equation, determine whether it represents a direct variation, an inverse variation, or neither.
SSSSS [86.1K]

we know that in direct variation as x increase y also increases.

in indirect variation x decreases y increase and vice versa.

in part a we have x at top (numerator ) and y at denominator it mean indirect variation (as x increases y decreases).

to find k we know that for indirect variation xy=k

if we rewrite the equation x=9/y we get xy=9

which mean k=9 .

in part b we have 4xy=20 if we simplify this equation we get

xy=20/4=5

so here if we rewrite in terms of x.

we get x=5/y which represents indirect variation.

and we know xy=k

we have xy=5 .so k=5

A culture started with 4,000 bacteria. After 2 hours it grew to 4400 bacteria. Predict how many bacteria will be present after 1
Art [367]
 <span>idk why they want the dratted "k" . it is so simple w/o it ! 
in the form y = ab^x, a = 4000, b = 4400/4000 = 1.1, x = t/2 
N = 4000*1.1^(13/2) = 7432 <------ 
----------------- 
now you won't be satisfied with simplicity, so 
4400 = 4000e^2k 
e^2k = 1.1 
k = ln 1.1/2 = .0477 to 4 dp 
N(13) = 4000e^(13*.0477) = 7436 <------ 

note that apart from a roundabout way, you get a less accurate ans !</span>

The solution to 4p+2&lt;2(p+5) is
gizmo_the_mogwai [7]

Answer:

p<4

Step-by-step explanation:

4p+2< 2(p+5)

Distribute: 4p+2<2p+10

Subtract 2 from both sides: 4p<2p+8

Subtract 2p from both sides: 2p<8

Divide and we get: p<4
