A mathematical expression known as an algebraic expression includes variables, constants, and algebraic operations (addition, subtraction, etc.). Expressions include terms. Here, y=3x.

The idea behind algebraic expressions is to represent numbers using letters or alphabets rather than giving their exact values. In algebraic basics, we learned how to express an unknown number using letters like x, y, and z. We will refer to these letters as variables from now on. An algebraic expression may have both constants and variables. Any amount that is added to a variable before it is multiplied by another is known as a coefficient.

y 12,15,18,21,24 y = __ x"

Answer:

x=y/m-a

Step-by-step explanation:

y=(x+a)m

Divide m on both sides

y/m=x+a

Subtract a on both sides

You answer is: 28 + 3[tex]x[/tex]

Since $28 is a one-time fee and does not have to be paid again for each and every ride, it does not need a variable in front of.

But for every ride you want, you pay $3 so you need the variable "[tex]x[/tex]" which represents how many times you ride.

For example, if you ride the roller coaster once, your total amount, in dollars, will be:

T = 28 + 3 * (1)

T = $31

But if you ride the roller coaster 3 times, your cost, in dollars, will be:

T = 28 + 3 * (3)

T = 28 + 9

T = $37

No solution is the answer of inequality.

What is inequality

The relationship between two values in an imbalanced algebraic statement is represented by an inequality in mathematics. One of the two variables can be larger than, more than or equal to, smaller than, or equal to another value by using a sign of inequality.  Make use of the following steps to solve an inequality: Step 1: Remove fractions by multiplying all terms by the fractions' lowest common denominator. Step 2 Combine like terms on both sides of the inequality to simplify. Step 3 Obtain the unknown on one side and the integers on the other by adding or subtracting quantities.

by using multiplication, we get that 28 BLT sandwiches can be made by Omar.

We are given that:

For every full head of lettuce used,

Number of tomatoes used = 5

Now, we will use multiplication.

2 full heads of lettuce used = 5 × 2 = 10 tomatoes used

Now, we also have:

2 tomatoes used = 1 1/20 pounds of bacon  used.

= 21/20 pounds of  bacon used.

1 tomato = (21 / 20) × (1 / 2) = 21 / 40 pounds bacon

10 tomatoes = (21 / 40) × 10 = 21 / 4 pounds bacon

Also,

3 / 4 pounds of bacon = 4 sandwiches

1 pound of bacon = 16 / 3 sandwiches.

21 / 4 pounds of bacon = (16 / 3) × (21 / 4) = 28 sandwiches

Therefore, by using multiplication, we get that 28 BLT sandwiches can be made by Omar.

Mai's bike ride was 1.5 times the length of Noah's bike ride

Fractions: A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Distance travelled by Mai in miles = 6 3/4 miles

Distance of Mai in improper fraction = 27/4

Distance travelled by Noah in miles = 4 1/2

Distance of Noah in improper fraction = 9/2

Length of Noah's bike ride as compared to Mai's bike ride = (27/4)/(9/2)

Answer:

x = 13

calculations in the pic hope it helps

Answer is 13

Step by step

1.4 + x / 6 = 2.4

We want to get rid of the 6 first

It is a divide so we want to do the inverse, which is multiply both sides by 6

1.4 + x * 6/ *6 = 2.4 * 6

Combine (the 6/6 becomes 1)

1.4 + x = 14.4

Now we want to isolate the x

Subtract 1.4 from both sides to solve for x

1.4 - 1.4 + x = 14.4 - 1.4

Depreciation is the decline in the value of an asset with the passage of time. Depreciation is as a result of wear and tear of an asset. The price of an item would decline when it depreciates.

Percentage is the fraction of an amount that is expressed as a number out of hundred. Percentage is used to measure the frequency of data. The sign that represents percentage is %. To convert a number to percentage, multiply the number by 100.

Percent depreciation = (value of the mountain bike today / value of the mountain bike last year) - 1

Hence, let's open the bracket on the left side of the equation

−3(m − 4) = − 6

- 3m + 12 = -6

subtract 12 from both sides of the equation

- 3m + 12 = -6

- 3m + 12 - 12 = -6 - 12

- 3m = - 18

The rate of change of the divers elevation = 19.274

Given,

The depth to which the Scuba dove = -69 [tex]\frac{9}{10}[/tex] feet

The rate at which he dove = -21.5 feet per min.

The time which he spent at the elevation = 12.5min.

The elevation the diver then ascended to -38 [tex]\frac{9}{10}[/tex] feet

Thee total time for the dove = 19 [tex]\frac{1}{8}[/tex] minutes.

Therefore, the time [tex]t_{d}[/tex] with which the scuba diver descended to -69 [tex]\frac{9}{10}[/tex] feet

is given as follows:
[tex]t_{d} = \frac{Distance}{speed}[/tex] = [tex]= \frac{-69\frac{9}{10} }{-21.5}= \frac{-681}{-21.5}[/tex] = 3.167 minutes

The time [tex]t_{e}[/tex], it took the scuba diver to elevate to -38 [tex]\frac{9}{10}[/tex] feet is given as follows:

[tex]t_{e}[/tex] = 19 [tex]\frac{1}{8}[/tex]minutes - (3.167 + 10.5) minutes = 5.458 minutes

The rate of change of the divers elevation = (Final elevation - Initial elevation)/(Time taken).

∴ The rate of change of the divers elevation

= (-38 [tex]\frac{9}{10}[/tex] - (-69 [tex]\frac{9}{10}[/tex] )) / 5.458 min

=(37.1 - (-68.1))/ 5.458 min
