Hello!
[tex]\large\boxed{2x - 8 = 7 - 3x \text{ and } 4(x - 1) = x + 5}[/tex]
We can go through each equation to solve:
1.
x + 3 = 4(x - 1) + 2
Distribute the coefficient outside of the parenthesis:
x + 3 = 4(x) + 4(-1) + 2
Simplify:
x + 3 = 4x - 4 + 2
x + 3 = 4x - 2
Subtract x from both sides:
3 = 3x - 2
Add 2 to both sides:
5 = 3x
Divide both sides by 3:
5/3 = x. This is not the answer.
2.
2x - 8 = 7 - 3x
Add 3x to both sides:
5x - 8 = 7
Add 8 to both sides:
5x = 15
Divide both sides by 5:
5x/5 = 15/5
x = 3. This is an answer.
3.
3(x + 2) = 14 - x
Distribute:
3(x) + 3(2) = 14 - x
3x + 6 = 14 - x
Add x to both sides:
4x + 6 = 14
Subtract 6 from both sides:
4x = 8
Divide both sides by 4:
4x/4 = 8/4
x = 2. This is not an answer.
4.
4(x - 1) = x + 5
Distribute:
4x - 4 = x + 5
Subtract x from both sides:
3x - 4 = 5
Add 4 to both sides:
3x = 9
Divide both sides by 3:
3x/3 = 9/3
x = 3. This is an answer.
5.
5 - 2(x + 1) = x
Distribute:
5 - 2x - 2 = x
Simplify:
3 - 2x = x
Add 2x to both sides:
3 = 3x
Divide both sides by 3:
3/3 = 3x/3
x = 1. This is not an answer.
6.
6(x - 4) = 2x
Distribute:
6x - 24 = 2x
Subtract 6x from both sides:
-24 = -4x
Divide both sides by -4:
-24/(-4) = -4x/(-4)
x = 6. This is not an answer.
Answer:
2x - 8 = 7 - 3x
4(x -1) = x + 5
Step-by-step explanation:
2) 2x - 8 = 7 - 3x
2x + 3x - 8 = 7
5x - 8 = 7
5x = 7 + 8
5x = 15
x = 15/5
x = 3
4) 4(x -1) = x + 5
4x - 4 = x + 5
4x - 4 - x = 5
3x - 4 = 5
3x = 5 + 4
3x = 9
x = 9/3
x = 3

Answer:
The perimeter of a rectangle is the sum of twice the length and twice the width. If the perimeter is at least 48 cm, then the minimum perimeter is 48 cm.
Let width = x
Let length = x + 4
Perimeter = 48
We can set an inequality for perimeter using the variables.
2x + 2(x + 4) ≥ 48
Solve for x.
2x + 2x + 8 ≥ 48
4x + 8 ≥ 48
4x ≥ 40
x ≥ 10
Substitute this value of x into the variable to get your width and length.
width = 10 cm
length = 14 cm

Step-by-step explanation:
Suppose a researcher compiled a data set consisting of the following variables for a sample of 200 women. For each variable, select whether it is discrete or continuous.
Variable Discrete Continuous
The number of college football games ever attended
The number of sons or daughters
The number of countries ever visited
Pounds of chocolate consumed in the past year
Shoe size
Height in inches
The number of pets currently living in the household
Answer:
Selecting whether each variable is discrete or continuous:
Discrete Variables:
The number of college football games ever attended
The number of sons or daughters
The number of countries ever visited
The number of pets currently living in the household
Continuous variables:
Pounds of chocolate consumed in the past year
Shoe size
Height in inches
Step-by-step explanation:
The researcher can distinguish a discrete variable from a continuous variable by checking if the value of the variable can be counted or measured. The researcher can count the value of a discrete variable, and she can measure the value of a continuous variable. In other words, a discrete variable represents countable objects and a continuous variable represents measurable amounts.
Using variable concepts, we have that the discrete variables are:
The number of college football games ever attendedThe number of sons or daughtersThe number of countries ever visitedThe number of pets currently living in the householdThe continuous variables are:
Pounds of chocolate consumed in the past year.Shoe size.Height in inches.What are continuous and discrete variables?Continuous variables: Can assume decimal values.Discrete variables: Assume only countable values, such as 0, 1, 2, 3, ...The variables that are countable, that is, discrete, are:
The number of college football games ever attendedThe number of sons or daughtersThe number of countries ever visitedThe number of pets currently living in the householdThe ones that can assume decimal values, hence being continuous are:
Pounds of chocolate consumed in the past year.Shoe size.Height in inches.You can learn more about continuous and discrete variables at brainly.com/question/16978770

A manufacturing process makes rods that vary slightly in length but follow a normal distribution with mean length 25 cm and standard deviation 2.60. What is the probability of randomly selecting a rod that is shorter than 22 cm
Answer:
The probability of randomly selecting a rod that is shorter than 22 cm
P(X<22) = 0.1251
Step-by-step explanation:
Step(i):-
Given mean of the Population = 25cm
Given standard deviation of the Population = 2.60
Let 'x' be the random variable in normal distribution
Given x=22
[tex]Z = \frac{x-mean }{S.D} = \frac{22-25}{2.60} = -1.15[/tex]
Step(ii):-
The probability of randomly selecting a rod that is shorter than 22 cm
P(X<22) = P( Z<-1.15)
= 1-P(Z>1.15)
= 1-( 0.5+A(1.15)
= 0.5 - A(1.15)
= 0.5 - 0.3749
= 0.1251
The probability of randomly selecting a rod that is shorter than 22 cm
P(X<22) = 0.1251

At a certain store volleyballs with a radius of 4 inches are sold in boxes in the shape of a cube. What is the volume of the smallest box that can hold a
Answer:
512 cube inches
Step-by-step explanation:
The radius of volleyballs is 4 inches, thus;
diameter of the balls = 2 x radius
= 2 x 4
= 8
The diameter of each ball is 8 inches.
Since the box has the shape of a cube, the smallest box that can hold a volleyball would have its dimensions equal to the diameter of the balls.
So that for the cube,
length = width = height = 8 inches
volume of a cube = [tex]l^{3}[/tex]
volume of the smallest box = [tex]8^{3}[/tex]
= 512 cube inches
The volume of the smallest box that can hold a volleyball is 512 cube inches.

Lin's family has traveled 25 miles which is only 20% of the trip.
How far is the whole trip?
a.
5 miles
c. 100 miles
b.
125 miles
d. 250 miles
Please hurry
Answer: 125 miles
Step-by-step explanation:
We know that 25 miles is 20% of the trip.
20% is 1/5 of 100, so that means we will multiply the number of miles driven by the denominator of the fraction.
25 × 5 = 125 miles
The answer to the question is 125 miles.

Graph the inverse of the function, f (x) = ( x+ 2)^3-4
Show all work in finding the inverse.
Answer:
The inverse of this function is:
[tex]f(x) = \sqrt[3]{x + 4} - 2[/tex]
Step-by-step explanation:
To find the inverse function, we can simply swap x and f(x) and solve for the latter:
[tex]x = (f(x) + 2)^3 - 4\\x + 4 = (f(x) + 2)^3\\\sqrt[3]{x + 4} = f(x) + 2\\f(x) = \sqrt[3]{x + 4} - 2[/tex]
