Mrs. Farnam is getting new carpet in her class! Her classroom is 12 meters long and 22 meters wide. How many square meters of carpet does she need?

Answer:

The correct answer is x = -4

Step-by-step explanation:

Step 1: 8x + 1 = -31 <----- This is the original equation.

Step 2: 8x + 1 - 1 = -31 - 1 <----- Subtract 1 from both sides.

Step 3: 8x = -32 <----- Simplify

Step 4: 8x/8 = -32/8

             x = -4

Hope this helps! :D

Answer:

the water level decreases by 5 feet per hour

Step-by-step explanation:

firstly the bar is going downwards, hence ,making a loss, decrease etc

so 1st and 3rd are out

initially we had 30ft of water

after

1 hr = 25 ft

- 5 ft decreased

2hrs = 20 ft

- 5 ft decreased again from the previous time checked

3hrs = 15 ft

- 5 ft decreased 1 hr ago

hence the water level decreases by 5 feet per hour

Answer:

A, C, E

Step-by-step explanation:

The required relation whose constant of proportionality matches with the constant of proportionality given in the graph.

Given that,
A curve is shown in the graph, it is to be determined that the constant of proportionality of the curve matches one of the curves given in the options.

Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense that are they directly proportional or inversely proportional to each other.

Here,
Constant of proportionality  for the given function,

y/x = 2 / 8 = 0.25

Since the constant of proportionality of the functions mentioned in Option A, C and E matched with the given graph.

Thus, the required relation whose constant of proportionality matches the constant of proportionality is given in the graph.

Answer:

$6.25

Step-by-step explanation:

Each football costs the same amount, and each basketball costs the same amount.

Let the cost of:

Footballs = f

Basketballs = b

Hence, we have the following system of equations

At the first store, the coach paid $110 for 5 footballs and 14 basketballs.

5f + 14b = 110

At the second store, the coach paid $82.50 for 10 footballs and 6 basketballs.

10f + 6b = 82.50

What was the cost in dollars of each basketball?

5f + 14b = 110..... Equation 1

10f + 6b = 82.50.....Equation 2

We solve using Elimination method.

Multiply Equation 1 by 10 and Equation 2 by 5 to eliminate f

50f + 140b = 1100.... Equation 3

50f +30b = 412.5.......Equation 4

Subtract Equation 4 from Equation 3

110b = 687.5

b= 687.5/110

b = $6.25

Therefore, the cost of one basketball in dollars = $6.25

Answer:

x should be -3

Step-by-step explanation:

f(x) = 5/3x + 10

f(-3) = (5*-3)/3 + 10

f(-3) = -15/3 + 10

f(-3) = -5 + 10

f(-3) = 5

g(x) = -2x - 1

g(-3) = -2(-3) - 1

Negatives cancel out

g(-3) = 2(3) - 1

g(-3) = 6 - 1

g(-3) = 5

5 is equal to 5, so x should be -3 in this case.
