Answer:

c =2

Step-by-step explanation:

2(6c+2)+3c=2 (19 -c)

1. Distribute

2(6c +2 ) + 3c = 2 ( 19 - C )

12c + 4 +3c = 2 (19 - C )

2. Combine like terms

12c + 4 + 3c = 2 ( 19 - c )

15c + 4 = 2 (19 - c )

3. Rearrange terms

15c + 4 = 2( 19 - C )

15c + 4 = 2 ( -c + 19 )

4. Distribute

15c + 4 = 2 ( -c + 19 )

15c + 4 = -2c + 38

5. Subtract 4 from both sides of the equation

15c + 4 = -2c + 38

15c + 4 -4 = -2c + 38 -4

6. Simplify

Subtract the numbers

Subtract the numbers

15c = -2c +34

7. Add 2c to both sides of the equation

15c = -2 +32

15c +2c = -2c + 34 + 2c

8. Simplify

Combine like terms

Combine like terms

17c = 34

9.Divide both sides of the equation by the same term

17c = 34

17c/17 = 34/17

10. Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

c = 2

Step-by-step explanation:

The expression to show the cost in dollars of the kit after the discount is 0.8x.

A school supply kit costs x dollars. A sale offers a 20% discount on the kit.

Therefore, the expression that shows how to find the cost in dollars of the kits after the discount.

Hence, the expression is as follows;

An algebraic expression consists of unknown variables, numbers and arithmetic operators like addition and subtraction.

Hence,

cost in dollars after discount = x - 20%x

cost in dollars after discount = x - 0.2x

cost in dollars after discount = 0.8x

Answer:

2

Step-by-step explanation:

Use the method

Change in output  / Change in input

The input progresses by 1, and y progresses by 2.

We will plug the numbers in.

Then simplify.

2/1 = 2

Hence, the rate of change is 2.

Answer:

£39

Step-by-step explanation:

Nick and June wins some money and share in the ratio 5:3

The difference = 5-3

= 2

Since Nicki receives £26 and his shares is 2

= 26/2

= 13

Therefore June shares can be calculated as follows

= 3×13

= 39

Hence June shares is £39

Answer:

You would pay $90 now for an item that used to cost $150.

Step-by-step explanation:

Here's how I thought of it. There are two ways to solve this problem.

Because we know that the item is discounted by 40%, that leaves 60% of its price left. (100% price - 40% price = 60% price).

Thus, you would multiply $150 by 0.6 (or, 60% in decimal form), which equals $90.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Alternatively, you could also multiply $150 by 0.4 and just subtract what you get from the total. That number is 60, and $150 - $60 = $90.

Use whichever way makes more sense to you!

Answer:

yep, whats up

Step-by-step explanation:

The degree of rotation about the origin will cause the triangle below to map onto itself is 360 degree.

Option A is correct.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

In the figure ABCD, is transformed to figure A'B'C'D'.

A figure will be mapped onto itself if it circles the graph 360 degrees.

As there are 360 degrees in a circle, the figure has just completed a full circle and returned to where it was before rotating.
