Answer:

[tex]r = 13[/tex]

Step-by-step explanation:

[tex](8r + 5) + (5r + 6) = 180 \\ 13r + 11 = 180 \\ 13r = 180 - 11 \\ 13r = 169 \\ \\ r = \frac{169}{13} \\ \\ r = 13[/tex]

Answer:

Step-by-step explanation:

first, let the numbers be x and y.

so by question we have,

x+y=54.......(I)

x-y=116......(I I)

now, solve it through elimination method,

x+y=54

x-y=116

here, y and y cancelled out and we get,

or, x+x=54+116

or, 2x=170

or, x=170/2

therefore, x=85

now put value of x in any equation. let's put in eqn (I), we get,

or, x+y=54

or,85+y=54

or, y=54-85

so, y= -31

therefore, the numbers are 85 and - 31.

Answer:

The answer is C

Step-by-step explanation:

t = bill for the customer

h= number of hours Dj worked

1) t = 75h + 35

This is wrong because h represents the number of hours the Dj worked. 75 is how much the customers paid as a setup fee.

2) t = 35 + 75

This is wrong because it's asking you to use "h" and "t" to determine the total. This is just a regular equation.

3) t = 35h + 75

This is right because as it says in the problem "The price of the Dj is $35 per hour" It also says use "h" to represent the number of hours the DJ works.

The "t" is used for the customer bill and 75 represents the setup fee

4) h = 35t + 75

This is wrong because h respresents how many hours the DJ works.

"t" represents the bill for the customer. The "t" would be in the beginning of the equation and the "h" would be behind the amount the DJ got paid per hour.

Step-by-step explanation:

A person heart beats is 4.2 x 10∧7

there are 7,600,000,000= 7.6 x 10∧9

the heartbeats for all the people here on earth= 4.2 x 10∧7 x 7.6 x 10∧9

choosing like terms

4.2 ×7.6×10∧7×10∧9

31.92x10∧(7+9)

31.92×10∧16

a=31.92

b=16

Answer:

[tex]3.192*10^1^7[/tex]

Step-by-step explanation:

To find this value, multiply the two values given:

4.2x10^7 = 4.2 x ( 10 x 10 x 10 x 10 x 10 x 10 x 10) = 42000000

42000000 x 7600000000 = 319200000000000000

Then convert 319200000000000000 into scientific notation:

319200000000000000 = 3.19200000000000000

Cut off all the zeroes and I moved the decimal 17 places to the left, so the exponent will be positive:

Step-by-step explanation:

The equation of the line is y = ( 4/3 )x + 2.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that the equation is parallel the line y = ( 4 / 3 )x + 8 and passes through the point ( -6 , -6 ).

The general equation of the line is

y = mx + c

The slope of the required line will be the same as the slope of the line parallel to the required line.

m = ( 4 / 3 )

The equation of the line will be written:-

y = mx + c

y = ( 4 / 3 )x + c

-6 = ( 4 / 3 ) x -6 + c

c = 2

y = ( 4/3 )x + 2

Therefore, the equation of the line is y = ( 4/3 )x + 2.

Answer:

B

Step-by-step explanation:

|15-12|/4 = 3/4

|(-21+9)/8| = |-12/8| = 12/8 = 3/2 (Simply)

3/4 - 3/2 = -3/4

So the answer is B.

Answer: no

Step-by-step explanation:

an example of a linear equation is x + 1. linear means a straight line. In a linear, the highest exponent on the x opponent is 1. in the equation 3x^2 + 2, the highest exponent on the x opponent is 2 which means this is a quadratic not a linear.

It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal​ value is $10

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Let x represent the number of​ 30-day periods until the value of the gift cards will be equal.

Tavon has a gift card for $90 that loses $4 for each​ 30-day period it is not used. This means that x 30-day periods, the amount left would be

90 - 4x

He has another gift card for $ 80 that loses $3.50 for each​ 30-day period it is not used. This means that x 30-day periods, the amount left would be

80 - 3.5x

For the amounts left on each card to be the same, the number of periods would be

90 - 4x = 80 - 3.5x

90 - 80 = - 3.5x + 4x

10 = 0.5x

x = 10/0.5

x = 20

The value of each card when they have equal​ value is

90 - 4 × 20 = 90 - 80

= $10

Therefore, It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal​ value is $10

Step-by-step explanation:

D) $180.68

At the beginning you have 68.02 plus the 169.23 deposit which makes a new total of 237.25.Then you spend 31.57 so the new equation is (237.25-31.57)

which is 205.68 then you spend another 25 for gas (205.68-25=180.68)

So your answer is $180.68

Answer:

y = 3

Step-by-step explanation:

If the line needs to be parallel to the x axis, it must be Horizontal. The formula for lines like this is y= mx+c with m being the gradient. With a horizontal line, the gradient is 0 and therefore we get y=c.

To find c, we need to find the y intersect which is where the line passes through the y axis. Since it is horizontal and passes through the dot, we can find that c = 3 as the dot is at 3 on the vertical axis.

From this, we can see that the equation is y = 3.

Answer:

3

Step-by-step explanation:

the x-axis is horizontal and the numbers above and below it are 4 and 2 and the dot was right on the line so it was 3
