Step-by-step explanation:

The value of the mass when I is 73 will be m = 14.4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that when an object of mass m kilogram is attached to the other end of the spring, the spring stretches to a length of / centimeters as shown in the equation l = 24 +3.4m.

The mass will be calculated as below,

73 = 24 + 3.4m

49 = 3.4m

Divide by 3.4 into both sides

14.4 = m

Answer:

[tex]x=\frac{576}{11}[/tex]

Step-by-step explanation:

13x - 12x + 45 * 12 = 14 - 12x - 10.5

Multiply first

13x - 12x + 540 = 14 - 12x - 50

Combine like terms

x + 540 = 12x - 36

Subtract x from both sides

540 = 11x - 36

Add -36 to both sides

576 = 11x

Divide both sides by 11

[tex]x=\frac{576}{11}[/tex]

Answer:

Step-by-step explanation:

The question is not clear on what to solve for, but we can solve for the number of weeks in which the two funds will have the same amount.

let the total fund funds be y

and the number of weeks be w

For John's fund the expression is

y=45w+1814------1

Marco's College Fund

y=25 w+1744---------2

equating 1 and 2 we have

45w+1814=25w+1744

45w-25w=1744-1814

20w=-70

divide both sides by 20 we have

w=-70/20

w=-3.5

this means that in 3 and half weeks the two funds will have the same amount in them

Answer:

[tex]\frac{4}{3}[/tex]

Step-by-step explanation:

(2,1) (8,9)

The formula that you would use is:

[tex]\frac{y_{2}-{y_1} }{x_2-x_1}[/tex]

So, 2 could be [tex]x_1[/tex] and 1 could be [tex]y_2[/tex]

and 8 could be [tex]x_2[/tex] and 9 could be [tex]y_2[/tex]

When we insert these numbers into the equation, we get:

[tex]\frac{9-1}{8-2}[/tex]

When we solve that we get:

[tex]\frac{8}{6}[/tex]

Now we simplify it by dividing both the numerator and denominator by 2, which would give us:

[tex]\frac{4}{3}[/tex]

Answer:

135/2

Step-by-step explanation:

In 1 day the dog eats 9/4 lbs

In 30 days the dog eats (9/4) * 30 lbs

                                     = (9 * 30) / 4

                                     =  135/2

Answer:

independent: number of tickets purchased;

dependent: total cost;

rule: f(x) = 60x

Step-by-step explanation:

The independent variable is the input of a function (the variable whose value determines the value of the output, or dependent variable). In this case, the independent variable is the number of tickets purchased.

The dependent variable is the output of a function (the variable whose value depends on the value of the input, or independent variable). In this case, the dependent variable is the total cost of all tickets purchased.

The total cost of all tickets purchased is equal to $60 times the number of tickets x. Therefore, a function rule for the total cost of all tickets purchased is f(x) = 60x.

The correct matches are;

1) (-7) (-1.2) =  8.4

2) 5 =  (-2 1/2) (-2)

3) -5 = (2.5) (-2)

4) (7) (-1.2) = - 8.4

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expressions are,

a) (-7) (-1.2)

b) 5

c) (-2 1/2) (-2)

d) -5

e) (2.5) (-2)

f) 8.4

g) (7) (-1.2)

h) -8.4

Now, Solve the expressions in simplest form;

a) (-7) (-1.2) = 8.4

b) 5 = 5

c) (-2 1/2) (-2) = -5/2 x - 2 = 5

d) -5 = -5

e) (2.5) (-2) = -5

f) 8.4 = 8.4

g) (7) (-1.2) = - 8.4

h) -8.4 = -8.4

Thus, The correct matches are;

1) (-7) (-1.2) =  8.4

2) 5 =  (-2 1/2) (-2)

3) -5 = (2.5) (-2)

4) (7) (-1.2) = - 8.4
