The rate of change is -6c per hour.

42c/7=6.

I believe the rate of change is negative because the question states that the temperature is decreasing.

Answer:

2

Step-by-step explanation:

Given:

-2(1-4x)=3x+8

Let's distribute the parenthesis

-2+8x=3x+8

Let's subtract -3x from both sides

-2+5x=8

Let's add 2 to both sides

5x=10

Now, let's divide both sides by 5 to get x alone

x=2

Hope this is helpful

Scrat [10]

<h3>What is simple interest?</h3>

It is defined as the interest on the based on the principal amount, it does not include the compounded amount. The interest calculate on the initial amount or borrowed amount.

We know the formula for the simple interest is given by:

I = PRT

Where I is the simple interest.

P is the principal amount

R is the rate of interest

We have in the question:

I = $180

R = 2% = 0.02

T = 1  year

Put the above values in the formula, we get:

180 = P(0.02)(1)

P = $9000

The additional interest Benson pay each month is:

= 9000/12

= $750

Thus, the additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year option (b) is correct.

The sandwich shop offers combo meals with a choice of one sandwich, one side, and one drink. On total there are 560 combos avail
Leto [7]
There are 7 sides available.

The fundamental counting principal tells us to find the total number of combinations of independent items, multiply the number of choices from each one (choices x choices x....)

This means that drink x sides x sandwiches = 560.  We know there are 16 sandwiches and 5 drinks.  Let S be the number of sides:
15(6)(S) = 560
80S = 560

Divide both sides by 80:
80S = 560/80
S = 7
