<em>Hello Human!!</em>

<em>Your answer is below!!</em>

Step-by-step explanation:

Simplifying:

4x + 1 = 2x + -5

Reorder the terms:

1 + 4x = 2x + -5

Solving:

1 + 4x = -5 + 2x

Solving for variable x.

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

Add -2x to each side of the equation.

1 + 4x + -2x = -5 + 2x + -2x

Combine like terms: 4x + -2x = 2x

1 + 2x = -5 + 2x + -2x

Combine like terms: 2x + -2x = 0

1 + 2x = -5 + 0

1 + 2x = -5

Add -1 to each side of the equation.

1 + -1 + 2x = -5 + -1

Combine like terms: 1 + -1 = 0

0 + 2x = -5 + -1

2x = -5 + -1

Combine like terms: -5 + -1 = -6

2x = -6

Divide each side by 2.

x = -3

Simplifying

x = -3

<em>So, Your answer is </em>x = -3.

<em>P.S </em><em>Tell me if this is wrong...</em>

<em />Good Luck!!<em />

Answer:

x=-3

Step-by-step explanation:

subtract "2x" to "4x + 1" and that'll leave -5 by itself and leave 2x+1 on the left and -5 on the right then subtract -1 to -5 and it'll add up to -6 then after that you'd divide 2x to -6 and get -3 and it'll leave 'x' by itself so therefore X = -3

Mai biked 6\frac{3}{4} miles today, and Noah biked 4\frac{1}{2} miles.
Alinara [238K]

It was 1.5 times the length of Noah's bike ride as Mai’s bike ride.

The problem we dealing with is related to mixed numbers which are referred to as mixed numbers and could be the whole number, and a proper division spoke together. It for the most part speaks to a number between any two whole numbers.

Since we are providing mai's rate which is  6 3/4  miles and Noah's  rate of 4 1/2 miles, So in  order to find the time the length of Noah's ride is compared to Mal's, we just need to divide the given rates by each other

=> 6 3/4 divided by 4 1/2,  

=> 27/4 divided by 9/2, (The result is an improper fractions)

=> 27/4 X 2/9

=>3/2

=> 1.5

Help please ! Math problem
morpeh [17]

Let's solve your equation step-by-step.

5=(−4)(8)+b

Step 1: Simplify both sides of the equation.

5=(−4)(8)+b

5=−32+b

5=b−32

Step 2: Flip the equation.

b−32=5

Step 3: Add 32 to both sides.

b−32+32=5+32

b=37

A collection of 5 positive integers has mean 4.4, unique mode 3 and median 4. If an 8 is added to the collection, what is the ne
Sphinxa [80]

9514 1404 393

Answer:

  4.5

Step-by-step explanation:

It appears the 5 integers must be {3, 3, 4, 5, 7}.

For the mode to be unique, there must be more than one '3', and there cannot be any other repeated numbers. For 4 to be the median, it must be the 3rd-highest number. Then the remaining numbers must be integers greater than 4 with a sum of 12 for the mean to be 4.4.

When 8 is added to the collection, the median is now the average of 4 and 5, so is 4.5.

The new median is 4.5.

_____

<em>Comment on vocabulary</em>

<u>mean</u>: the sum of numbers divided by the number of numbers. 5 numbers with a mean of 4.4 will have a sum of 5×4.4 = 22.

<u>median</u>: the middle number of a collection of an odd number of numbers, when sorted from lowest to highest. It is the 3rd number of a group of 5 numbers. When there are an even number of numbers in the group, the median is the average of the middle two in the sorted list. Here, that means the 3rd number in the list of 5 is '4'. When 8 is added, 4 becomes one of the numbers contributing to the average that will be the new median.

<u>mode</u>: the member of the group that appears the most times. When the mode is unique, it means there are no other numbers repeated as often. Here, we know the 3rd number (of 5) is 4, so there can only be two numbers '3' in the collection. That 3 is the unique mode means no other numbers are repeated at all.
