Step-by-step explanation:

Length of driveway = 1/12 miles

Daily goal = 1 1/2 miles

Number of times he has to run the length of the driveway:

Daily Goal / length of driveway

= 3/2 miles ÷ 1/12 miles

= 3/2 * 12 / 1

= 36 /2

= 18

Answer:

The kind of triangle that will form the shape of her flower bed is;

A scalene triangle

Step-by-step explanation:

In creating the triangular flower bed, the length of the scraps Mariah uses are;

The length of one scrap = 2.2 feet long

The  length of the second scrap = 4.25 feet long

The  length of the third scrap = 5.75 feet long

From the given length of the scraps, the kind of triangle that will form the shape of her flower bed is a scalene triangle

A scalene triangle is a triangle that the length of all the three sides are different and the measures of the three interior angles of the triangle are therefore also different

Answer:

x = -3

Step-by-step explanation:

24 = 12 - 4x

24 - 12 = -4x

12 = -4x

12/-4 = x

x = -3

Answer:

x=-3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

24=12−4x

24=12+−4x

24=−4x+12

Step 2: Flip the equation.

−4x+12=24

Step 3: Subtract 12 from both sides.

−4x+12−12=24−12

−4x=12

Step 4: Divide both sides by -4.

−4x

−4

=

12

Answer:

1) w = x+2

2) L = 12

3) w = 9

4) A = 108

Step-by-step explanation:

The rectangle has a length of x+5 and a perimeter of 4x+14.

Perimeter of a rectangle is given by all the lengths plus all the widths, ie 2*width and 2*length.

Perimeter = 2w + 2L

4x+14 = 2w + 2(x+5)

4x + 14 - 2x - 10 = 2w

w = 2x + 7 - x - 5

w = x+2      Width of the rectangle in terms of x.

If perimeter of rectangle is 42, what is the length?

Perimeter = 42 = 4x+14

28 = 4x

x = 7

L = x+5

L = 7+5

L = 12

If perimeter of rectangle is 42, what is the width?

Perimeter = 42 = 4x+14

28 = 4x

x = 7

w = x+2

w = 7+2

w = 9

Area equals length times width. What is the area of the rectangle.

A = L*w

A = 12*9

A = 108

Answer:

I think its -120 but am not sure so sorry if its wrong

Answer:

Step-by-step explanation:

what makes these tough is that you have to remember that the total of the angle is known,  you know it to be 180 ° , so since you know the total just set all the part equal to that

180 = 4x + 6x-20 + 5x - 10

now you can slove for x with your mad algebra skilz  :) if you don't have those yet. it's okay.. most people don't  :D  Super hero's and math whizzes only, seem to have those.  :D

180 = 15x -30

210 = 15x

14 = x  

now that we know what x is , plug it into the angle BCE

BCE = 6(14) -20

BCE = 84 -20

BCE = 64 °

Answer:

Step-by-step explanation:

- The # in front of x will be the number that hits on the y-axis

- The # after x or the slope, ex: y = -1/2x + 2, is how much you move to hit the next point on the graph

-  2 would actually be 2/1 so move up 2 and right 1 (if the number or fraction is negative then go up and to the left

- So y = -2x - 1/2, negative slope. Start at -2 on y-axis and go up 1 then left 2.

The circumference of a circle is 19.468 meters, the radius of the circle is: 3.1 m

When it comes to geometry, a circle's or ellipse's circumference is its perimeter. In other words, the circumference would be the length of the circle's arc if it were opened out and straightened out to a line segment. The radius surrounding any closed figure is known as its perimeter more generally. The distance in a straight line around a circle is known as its circumference. Or, to put it another way, the circumference of a circle is the length of a straight line formed by opening up the circle.

Given that,

circumference = 19.468 m

So, as we know

circumference = 2 × π × radius

or, 19.468 = 2 × π × radius

or, radius = 19.468 / 2π

or, radius = 3.1 m

correct option: 3.1 m

Answer:

=-18x+20

Step-by-step explanation

:

Answer:

-18x+20

Step-by-step explanation:

5+(-3)(6x-5)

Distribute the -3 with the 6x-5.

-3×6x=-18x,  -3×-5=15

5+-18x+15

The -18x is done, because there are no other like terms for it to add or subract with.

5 and 15 can add for 20

-18x+20

Key terms:

Distribute: To multiply a number by 2 or more numbers, often using parenthasis   6(5+7)= 30+35

Like terms: Coefficients with the same variable, or numbers without a variable can be added or subtracted. Unlike terms cannot be added or subtracted. Does not apply to multiplication or division.
