Answer:

4−2x<−3

Step-by-step explanation:

check:

now --- 4°

after 1 hr --- 2°

after 2 hrs--- 0°

after 3 hrs--- -2°

after 4 hrs--- -4°

so between 3 and 4 hrs it will reach -3°

4-2x < -3

-2x < -7

x > 3 1/2

Answer:

88 cups of batter

Step-by-step explanation:

We are told from the the question: Selena used:

132 pancakes was made from = 44 cups of pancake batter

how many cups of batter will Selena use to make an additional 264 pancakes?

132 pancakes = 44 cups of pancake batter

264 pancakes = ??

Cross Multiply

= 264 × 44/132

= 11616 / 132

= 88 cups of pancake batter.

Therefore, selena would be needing 8( cups of pancake butter to make an additional 264 pancakes.

Answer:

The temperature at the end of the day is 2 degrees

Step-by-step explanation:

Here, we are interested in calculating the temperature at the end of the day.

In the question, we are told that at the beginning of the day, temperature was -14 degrees.

But throughout the day, the temperature increased by 16 degrees;

Thus, the temperature at the end of the day = -14 degrees + 16 degrees = 2 degrees

This is an incorrect question, the correct question is given below.

Martin is building a model. He cuts two pieces of wood that are each [tex]6\frac{1}{3}[/tex] inches long from a board with a total length of 18 inches.  What is the length, in inches, of the remaining part of the board?

Answer : The length of the remaining part of the board is [tex]5\frac{1}{3}[/tex] inches.

Step-by-step explanation :

As we are given that:

Total length of the board = 18 inches

Length of each piece of wood cut from the board = [tex]6\frac{1}{3}[/tex] inches = [tex]\frac{19}{3}[/tex] inches

Length of 2 pieces of wood cut from the board = [tex]2\times \frac{19}{3}[/tex] inches

                                                                               =  [tex]\frac{38}{3}[/tex] inches

Length of the remaining part of the board = Total length of the board - Length of 2 pieces of wood cut from the board

Length of the remaining part of the board = [tex]18-\frac{38}{3}[/tex] inches

                                                                      = [tex]\frac{54-38}{3}[/tex] inches

                                                                      = [tex]\frac{16}{3}[/tex] inches

                                                                      = [tex]5\frac{1}{3}[/tex] inches

Therefore, the length of the remaining part of the board is [tex]5\frac{1}{3}[/tex] inches.

Step-by-step explanation:

3x x 10 = 22

3x x 10 - 10 = 22 - 10

3x = 12

3x ÷ 3 = 12 ÷ 3

x = 4

Answer:

384

Step-by-step explanation:

The solution is: Therefore, there are 248 windows on the first eight floors.  The answer is letter A. 248

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

The ground floor:  52 windows.

We will use the arithmetic sequence:

a 1 = 52

d = - 6

The given situation is an arithmetic sequence with the first term equal to 52 and has a common difference of -6.

The formula for the summation (S) of the terms in arithmetic sequence is

                                  S = (n/2) x (2a1 + (n - 1) d)

where n is the number of term, a1 the first term, and d the common difference.

Substitute the given from the problem,

                                         S = (8/2) x ( (2)(52) + (8 - 1)(-6))

                                             S = 248

Therefore, there are 248 windows on the first eight floors.

The answer is letter A. 248

The windows of a downtown office building are arranged so that each floor has six fewer windows than the floor below it. If the ground floor has 52 windows, how many total windows are on the first eight floors?

Answer as a fraction:  x = 5/2

Answer in decimal form:   x = 2.5

=====================================================

Explanation:

Replace f(x) with 5

So we go from f(x) = 2x to 5 = 2x

Now isolate x. We do so by dividing both sides by 2 (this undoes the multiplication of 2 on x)

So we get

5 = 2x

5/2 = 2x/2 ... divide both sides by 2

5/2 = x

x = 5/2

x = 2.5

CAN I GET BRANLIEST ANSWER PLEASE

Answer:

240 pesos

Step-by-step explanation:

Aquí, simplemente queremos calcular cuánto gastar en combustible para un viaje de 320 km si se gastaron 90 pesos en un viaje de 120 km.

La mejor manera de hacerlo es encontrar la cantidad gastada por kilómetro.

Por lo tanto, si se gastan 90 pesos en 120 km, se gastarán x pesos por kilómetro;

x * 120 = 90 * 1 120x = 90

x = 90/120 x = 3/4 = 0,75 pesos

Entonces se gastan 0,75 pesos por kilómetro

Entonces, para 320 km,

la cantidad a gastar será; 3/4 * 320 = 240 pesos
