Answer: Simplifying

4a + 3(a + 1) = 24

Reorder the terms:

4a + 3(1 + a) = 24

4a + (1 * 3 + a * 3) = 24

4a + (3 + 3a) = 24

Reorder the terms:

3 + 4a + 3a = 24

Combine like terms: 4a + 3a = 7a

3 + 7a = 24

Solving

3 + 7a = 24

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 7a = 24 + -3

Combine like terms: 3 + -3 = 0

0 + 7a = 24 + -3

7a = 24 + -3

Combine like terms: 24 + -3 = 21

7a = 21

Divide each side by '7'.

a = 3

Simplifying

a = 3

Vera_Pavlovna [14]

Answer:

$36.25

Step-by-step explanation:

To enter the park, Amanda pays 25 dollars.

+$25

It costs 1.25 for every ride that Amanda goes on.

Since we don't know the number of rides Amanda goes on, we will add a variable to represent the number of rides.

1.25x

Then, the passage says that Amanda goes on 9 rides. So, substitute 9 for x.

Equation: 25+1.25(9)

Then solve:

$36.25

posledela

Answer: Jennifer didn't randomly assign participants to the control and experimental group.

Step-by-step explanation: In the scenario discussed above, Jennifer failed to perform a random assignment of the participants who took part in the survey, that is the experimental group, those who receive the treatment and the control group, those who don't. Random assignment is required in other to address the issue of bias in our experiment. She was supposed to perform a random assignment of the participants to the two groups instead of asking them to make a choice.

the sum of four consecutive integers is 2174. what are the integers? (continuation) the smallest of four consecutive integers is
timofeeve [1]
The smallest of the four numbers is x.
Since the four numbers are consecutive, this means that each number is one more than the previous.
Therefore, the four numbers are:
x
x + 1
x+1 + 1 = x+2
x+2 + 1 = x+3

Now, we are given that the sum (s) of the four numbers is 2174
This means that:
s = x+x+1+x+2+x+3
s = 4x + 6

We are given that s = 2174. Substitute with s in the above equation and solve for x as follows:
2174 = 4x + 6
4x = 2174 - 6
4x = 2168
x = 2168 / 4
x = 542

Based on the above calculations, the four numbers are:
542, 543, 544 and 555
