<h3>1)</h3>

x = y + 5 \\ y = x - 5

<h3>2)</h3>

x =  \frac{3}{8} y \\ y =  \frac{8}{3}x

<h3> 3)</h3>

x =  - y - 2 \\ y =  - 2 - x

<h3>4)</h3>

x = 6y + 1 \\ 6y = x - 1 \\ y =  \frac{x - 1}{6}

<h3>5)</h3>

x = y - 11 \\ y = x + 11

<h3>6)</h3>

x = 8y \\ y =  \frac{x}{8}

<h3>7)</h3>

x =  \frac{ - 1}{3} y \\ y =  - 3x

basically \: flip \: x \: and \: y \: then \: solve \: for \: y

Answer:

1.) 20,160 cookies, 2.) 37,600 Letters to students in a different country 3.) 252.36 Exact form, Approximate form: 252

Step-by-step explanation:

The first question is written in standard form like this:

Standard Form: 315 x 64 = 20,160

Algebraically/Logical: 315 Packages x 64 Cookies = 20,160 Cookies in All

Therefore, Kenneth bought 20,160 Cookies

The second question is written like this:

Standard Form: 940 x 40 = 37,600

Algebraically/Logical Reasoning: 940 students x 40 letters = 37,600 letters written to students in a different country.

Note: This question has a random P 240, That will be erased so that is why the equation is 940 x 40

The third question is written like this:

Standard Form: 36 x 7.01 = 252.36

Approximate form: 36 x 7 = 252

Algebraically/Logical Reasoning: The standard form would explain it all but if I was answering this question I would round 7.01 to the one's place because there is no way you would get a decimal when trying to solve an even amount of cloths. So there are 36 squares in one table cloth, times that by 7 which is equal to 252 approximently.

a person goes from a sauna at 115°F to an out side temperature of -30°F. what is the change in temperature?
Oksana_A [137]

Whenever you're interested in computing the (absolute) difference between two values of a certain variable, you have to subtract the final value and the initial value. This is often written as delta:

\Delta x = x_{\text{final}} - x_{\text{initial}}

So, in this case, the final temperature is -30°F. The initial temperature is 115°F. So, the variation is

\Delta T = T_{\text{final}} - T_{\text{initial}} = -30 - 115 = -145

A negative delta indicates that the value decreased, which is our case.
