guapka [62]

Answer:

7 2/3 minutes

Step-by-step explanation:

We can write this equation in y = mx+b form

where m = 3 ft/min and b = -105 ft  

x is the number of minutes and y is the depth

y = 3 * x -105

We want to find when y = -82

-82 = 3x -105

Add 105 to each side

-82+105 = 3x-105+105

23=3x

Divide by 3

23/3 = 3x/3

23/3=x

Changing into a mixed number

3 goes into 23  7 times with 2 left over

7 2/3 minutes

When both parties discuss the terms of a contract they are
marysya [2.9K]
B - Negotiating.

This is because they are communicating, they haven't yet agreed to anything or committed to the contract as neither parties have signed, thus leading to both C and D to be incorrect.

A, however, is not exactly a term used for this situation - contracting is more of a term used to say someone contracted a disease or the flu or etc. 

Therefore, B would be correct as they are indeed negotiating the terms of the contract.

Hope this helps!

Answer:

$83 million

Step-by-step explanation:

29% of the charity's donated funds.

$24.1 million = donation

Let x = the total amount of donated funds

29/100 • x = 24.1

x = 24.1 • 100/29

x = 83.10

=83

Hope this helps :)

An electric guitar is on sale at 40% off. if the sale price is 179.94 ,what is the original.
n200080 [17]
Let x = original price
Knowing that multiplying the original price and the discount is the discount price. We formulate:
x(1 - 0.40) = 179.94
x(0.60) = 179.94
x = 179.94/0.60
x = 299.9
That is about 300 of the original price.
