If the m/n = 1/2, that means that m = 1 and n = 2

If the n/k = 2/5, that means that n = 2 and k = 5

Which gives us that m/k = 1/5 .

Answer:

216

Step-by-step explanation:

I'm sure there is a simpler way to do this but this is how I did it.

First divide 18 by 6 because it triples every 6 hours.

18/6=3

This means it will triple three times

Then triple the value three times

#1. 8x3=24

#2. 24x3=72

#3. 72x3=216

In 18 hours the virus will infect 216 people.

Solve x-5y=17 for y?

damaskus [11]

Answer:

Y = 12.

Explanation: Because 17- 5 is 12 and when you are doing problems like that, you are supposed to subtract the number behing the equal sign with the number in front of the equal sign. So, that would be 17- 5. And that gives you 12. So, Y=12.

PLEASE SHOW ALL WORK

Answer:

t = 2,3

Step-by-step explanation:

s (t) = t^2 + 2 t + 5

p (t) = 11 + 3 t

s (1) = 8

s (2) = 13

s (3) = 20

s (4) = 29

Now

$t^2 + 2 t + 5 = 11 t + 3t \\\\t^2 - t - 6 = 0\\\\t^2 - 3 t - 2 t - 6 = 0 \\\\(t-2)(t-3)=0\\\\t = 2, 3$

(b) The values are same at t =2 an t =3.

In the following exercises, multiply the binomials. Use any method.<br> 266. (3rs − 7)(3rs − 4)

Novay_Z [31]

Answer:

Hence the expression $(3rs-7)(3rs-4)=9r^2s^2-33rs+28$

Step-by-step explanation:

Explanation

The given expression is (3rs-7)(3rs-4).
We have to multiply the given expression.
Multiply the (3rs-7) by -4, multiply the (3rs-7) by 3rs then add like terms.

$\begin{matrix}{} & {} & {} & {} & 3rs & - & 7 \\ \times & {} & {} & {} & 3rs & - & 4 \\ \end{matrix}$

_________________

$\begin{matrix}{} & {} & {} & - & 12rs & + & 28 \\ {} & {} & 9{{r}^2}{{s}^2} & - & 21rs & {} & {} \\ \end{matrix}$

________________

$\begin{matrix}{} & {} & 9{{r}^2}{{s}^2} & - & 33rs & + & 28 \\ \end{matrix}$
