change per week?

Answers

Answer 1
Answer:

The average change per week is 3 cents per week if, over a 6-week period, the price of a gallon of gas increases by 18 cents.

What is the rate of change?

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that:

Over a 6 week period, the price of a gallon of gas increased by 18 cents.

Let x be the average change per week.

The numerator, which is found at the top of the fraction number, is referred as the numerator, and the denominator, which is found at the bottom of the fractional number, is referred as the denominator.

The value of x can be calculated as follows:

x = 18/6

x = 3 cents per week

Thus, the average change per week is 3 cents per week if, over a 6-week period, the price of a gallon of gas increased by 18 cents.

How much will you pay for 5 pounds of shrimp if the cost is 2 pounds for $10.99?

Answers

2 lbs. = $10.99

$10.99 + $10.99 = $21.98 (4 lbs.)

To add one more pound you just half the 2 lb price and add to the 4 lb value. 

$10.99 / 2 = $5.45 (1 lb)

$5.45 (1 lb) + $21.98 (4 lb) = $27.43 (5 lb)

5 pounds of shrimp would cost $27.43.
2 • $10.99 = $21.98 + $5.49 = $27.47

its as simple as adding up what you do and saving what you dont until the end

Answers

3h + 2p = 192 -->(-2) 2h + 3p = 213 -->(3) ------------- -6h - 4p = - 384 (result of multiplying by -2) 6h + 9p = 639 (result of multiplying by 3) --------------add 5p = 255 p = 255/5 p = 51 now sub 51 in for p in either of the original equations to find h 3h + 2p = 192 3h + 2(51) = 192 3h + 102 = 192 3h = 192 - 102 3h = 90 h = 90/3 h = 30 check... 3h + 2p = 192 2h + 3p = 213 3(30) + 2(51) = 192 2(30) + 3(51) = 213 90 + 102 = 192 60 + 153 = 213 192 = 192 (correct) 213 = 213 (correct) 1 hr of horseback riding (h) costs $ 30 1 hr of para-sailing (p) costs $ 51

Due tomarrow please help!!!!!!!!!!!!!!!!!!!!!!!!!  Identify the independent and dependent variables in the following statement. The more water flowing into the pool, the greater the water depth is in the pool. A. The independent variable is the depth of water in the pool, and the dependent variable is the rate that water is flowing into the pool. B. The independent variable is the rate that water is flowing into the pool, and the dependent variable is the depth of water in the pool.
