It's division what is so hard

Answer:

c=1

Step-by-step explanation:

Simplifying

3 + 2c = 5

Solving

3 + 2c = 5

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2c = 5 + -3

Combine like terms: 3 + -3 = 0

0 + 2c = 5 + -3

2c = 5 + -3

Combine like terms: 5 + -3 = 2

2c = 2

Divide each side by '2'.

c = 1

Simplifying

c = 1

Answer:

 =  4

Step-by-step explanation:

Subtract  15 from both sides of the equation

6+15=39

6+15−15=39 − 5

Simplify

6=24

Divide both sides of the equation by the same term

(6=24)/6

Simplify

=4

Answer:

x=16

Step-by-step explanation:

1 soccer ball =$12

2 makes $24.

24+16=40

so both coaches spend 8 bucks for 4 cones

Each cone costs $2, and the cost is calculated as follows: 8x = 40 - 2 *p, where p is equal to the cost of a football.

A linear equation is an algebraic equation of the form ax + by +c, is and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given that, Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount. Together the coaches spend $40.

Let x be the number price of the cone.

Thus each coach spends  = 4x  +12

Thus, in total, they spend = 40

4x  +12 +  4x  +12 = 40

8x = 40 -24

8x = 16

x = 2

Therefore, Each cone costs $2 and the equation for calculating the price of the cone is: 8x = 40 - 2 * the price of a football.

Answer:

4 red marbles and 6 blue marbles is the correct answwer

Step-by-step explanation:

Answer:

A.) 4 red marbles and 6 blue marbles

Step-by-step explanation:

If you times 2 x 2 then you will get 4

If you times 3 x 2 then you will get 6

And since the ratio is red : blue

2 : 3 is equivalent to 4 : 6

Just like  [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.

if you were to do a fraction graph, 2 of the 3 [tex]\frac{1}{3}[/tex] bars would be the same length of 4 [tex]\frac{1}{6}[/tex] bars:

The product of the above is the area of the garden and the walkway

Correct option is D

Answer:

D. the total area of the garden and walkway

Step-by-step explanation:

Sides of the rectangular garden:

w and w + 3

Add the width of the walkway, 2 feet from both sides, the total of 4 feet:

w + 4 and w + 7

The product of the above is the area of the garden and the walkway

Correct option is D

Hope this helps!

Step-by-step explanation:

(3.1415 * 10^2) area of base

(17) height

volume = area of base * height

volume = 3.1415 * 10^2 * 17

The volume of the cylinder is 533.8 cubic inches to the nearest tenths place

What information do we have?

Diameter of cylinder = 20 inch

Height of cylinder = 17 inch

Volume of Cylinder = πr²h

Volume of Cylinder = (3.14)(20/2)²(17)

Volume of Cylinder = (3.14)(10)(17)

When interpreting graphs of real world situations, the slope of each part tell you the average rate of change (increase or decrease) of the dependent variable with respect to the independent variable. This is, how much the dependent variable increased (or decrease) per each unit the independent varaible increased, in average.

slope = change in independent variable / change in dependent variable

slope = Δy / Δx

Answer:

y = 6 x − 3

Step-by-step explanation:

The slope-intercept form is  y = m x + b , where  m  is the slope and  b  is the y-intercept.

y = m x + b

Using the slope-intercept form, the y-intercept is  − 3 .

b = − 3

Answer:  

-3

Explanation:

I remember the formula to be y=mx+b, and mx representing the slope times x.  Therefore, b would equal the y-intercept, or in this case 3.  Using slope intercept form, you get -3.
