Answer:

9.07 [Rounded]

Step-by-step explanation:

535 divided by 59 is 9.07, which I rounded.

The value of the division 535 ÷ 59 is 9 with a remainder of 4 and the decimal form can be expressed as 9.067.

To find the value of division 535 ÷ 59, we can perform a long division.

To perform the calculation, we can use long division:

59 ) 535 ( 9

     - 531

     ______

         4

Divide the first digit of the dividend (5) by the divisor (59). Since 5 is less than 59, we bring down the next digit, making it 53.

Divide 53 by 59. The result is 0, as 53 is less than 59.

Bring down the next digit, making it 535.

Divide 535 by 59. The result is 9, as 59 can go into 535 nine times.

Multiply 9 by 59, which equals 531.

Subtract 531 from 535, which gives us a remainder of 4.

Therefore, the value of the division 535 ÷ 59 is 9 with a remainder of 4.

In decimal form, the division can be expressed as 9.067, indicating that 59 goes into 535 nine times with a remainder of 4.

Answer:

He drove 350 miles.

Step-by-step explanation:

I need points.

Brady drove 16.67 miles extra.

One type of operation in mathematics is division. We divide the expressions or numbers into the same number of components during this operation.

Given, Brady rented a car for two days at $25 a day plus $0.15 per mile.

His total bill is $102.50.

We divide the 102.50 by 25.

That means, 102.50 / 25

= 4 is quotient and 2.50 is remainder.

Now we divide 2.50 by 0.15

That means, 2.50 / 0.15

= 16.67 miles

Therefore, 16.67 miles, Brady drove.

Answer:

angle 1= 30 degrees

angle 2= 120 degrees

angle 3= 30 degrees

Step-by-step explanation:

A triangle is equal to 180 degrees so first step is to subtract 120 to get the total of your two missing angles

180-120=60

and since your two missing angles are equal to each other you can divide by 2 and you get your two missing angles

60 / 2 = 30

Answer:

143 acres.

Step-by-step explanation:

To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.

To find a percent of a number, multiply the percent by the number.

0.2% is equal to 0.002.

73,000 x 0.002 = 143

So, 143 acres of the forest is old-growth trees.

Step-by-step explanation:

Given

y = 2x - 3

if x = - 4 Then

y = 2 * ( -4) - 3

= -8 - 3

= - 11

Hope it will help :)

The value of y when the value of x is equal to the negative number 4 is negative 11 (-11).

Unknown variables are used to find the unknown values of the problem using the algebraic expressions.

The expression for the variable x and y are given as,

[tex]y=2x-3[/tex]

The x value for the above expression is given as,

[tex]x=-4[/tex]

The value of y for the above value of x has to be found out.  Put the value of x in the given expression to find the value of variable y as,

[tex]y=2(-4)-3[/tex]

Solve it further as,

[tex]y=2(-4)-3\\y=-8-3\\y=-11[/tex]

Hence, the value of y when the value of x is equal to the negative number 4 is negative 11 (-11).

Answer:

8x + 2y

Step-by-step explanation:

12x + 3y = 8 you need to transfer the no. 8 to left since it's positive, it will be negative once you tranfer that and the result is this 8x + 3y -8 =0. Then do it again on the second given, -4x = y + 8.

Tranfer the y variable to left, y is positive then it will be a negative. No need to transfer the no. 8. Then the result would be -4x - y + 8=0

To this solve this, wrote it like this:

12x + 3y –8

-4x - y + 8

If the points (1,3), (2, 1), (3,-1). (4.-3) lie on line k, then the slope of line k is -2

Option D is the correct choice

The points that lie on the line k are:

(1,3), (2, 1), (3,-1). (4.-3), and (5,-5).

We can find the slope of the line k by picking any two points on the line

The slope m of a line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

On the line k, let us select the points (1,3) and (2, 1)

x₁ = 1, y₁ = 3, x₂ = 2, y₂ = 1

[tex]m = \frac{1-3}{2-1} \\\\m= \frac{-2}{1}\\\\m= -2[/tex]

Therefore, the slope of the line k is -2
