Help me decrease 25 by 30%

Answers

Answer 1

Step-by-step explanation:

Percentage decrease = 30% × 25

New value = 25 - Percentage decreaseNew value =

25 - Percentage decrease =

25 - (30% × 25) =

25 - 30% × 25 =

(1 - 30%) × 25 =

(100% - 30%) × 25 =

70% × 25 =

70 ÷ 100 × 25 =

70 × 25 ÷ 100 =

1,750 ÷ 100 =

17.5

Absolute change (actual difference) =

New value - 25 =

17.5 - 25 =

- 7.5

Answer 2

Answer:

25 decreased by 30% equals 17.5

Step-by-step explanation:

To solve this, we need to make our equation to solve.

x/25=30/100

We did x because we don't know what 30% of x is. The 25 shows the total, while the right side shows the percent.

Now cross multiply

100x=750

Now divide both sides by 100.

you will get x=7.5

So now we know that 7.5 is 30% of 25. Now, subtract 7.5 from 25 in order to find out what 25 decreased by 30% is.

25-7.5=17.5

So the answer is 17.5

=====================================================

Explanation:

Parallel lines always have equal slopes, but different y intercepts. For example, the two lines y = 3x+5 and y = 3x+7 have a slope of 3. Refer to y = mx+b where m is the slope. Parallel lines never intersect.

-----------

For perpendicular lines, the two slopes always multiply to -1 assuming neither line is vertical nor horizontal. Consider the two linear equations

y = (1/2)x+5

y = -2x-7

The slopes 1/2 and -2 multiply to -1 which is enough to show that they are perpendicular lines. The two lines meet at a 90 degree angle.

To go from one slope to the other, we apply the negative reciprocal. That means we...

flip the fractionflip the sign

Applying the first step to 1/2 gets us 2/1 or 2. Then changing the sign has us go from 2 to -2. This process can be reversed.

-----------

For some of these equations, you'll need to rearrange things into either point-slope form or slope intercept form. This will allow you to read off the slope.

Point slope form is y-y1 = m(x-x1)

Slope intercept form is y = mx+b

For either case, all we care about is the variable m.

I'll show how problem 14 transforms into slope intercept form

x+2y = 14

2y = -x+14

y = (-x+14)/2

y = (-x/2) + (14/2)

y = (-1/2)x + 7

We see that m = -1/2 here. Anything parallel to this will have the same slope. The perpendicular slope is 2 after applying the negative reciprocal operation. Problems 13, 15, 16, 17, and 18 are going to follow similar steps.

Answer:

[tex]x = \frac{1}{2}y[/tex] or [tex]y = 2x[/tex]

Step-by-step explanation:

Basically, x is 2 times smaller than y, or

y is 2 times larger than x.

For example, when x equals 4, y is 2 times greater, so y = 4 * 2 = 8

Another example:

When y equals 12, x must be 2 times smaller than that, so x = 12 / 2 = 6

I don't know which one you're looking for, but try putting in

x = 1/2y or y = 2x

Answer:

the desired equation is y = 2x - 3

Step-by-step explanation:

Parallel lines have the same slope.  Thus, a new line parallel to y = 2x - 4 has the slope 2.  

Find the equation of the new line by writing out the slope-intercept form

y = mx + b.  Substitute -1 for y and 1 for x:

-1 = 2(1) + b, which yields b = -3

Then the desired equation is y = 2x - 3

Original line: y = -5/6x - 1

A line that is parallel to the original will have the same slope. To find the new y-intercept, we'll take the original line, plug in the given point, and solve for b.

y = -5/6x + b

-2 = -5/6(5) + b

-2 = -25/6 + b

b = 13/6

Parallel Line: y = -5/6x + 13/6

A line that is perpendicular to the original will have the opposite reciprocal slope. To find the new y-intercept, we'll take our perpendicular slope, plug in the given point, and solve for b.

y = 6/5x + b

-2 = 6/5(5) + b

-2 = 6 + b

b = -8

Perpendicular Line: y = 6/5x - 8

Number of Tickets Cost

2 $17.00

3 $25.50

4 $34.00

5 $42.50

Based on this proportional relationship, find the constant of proportionality (r). Using the value for r, enter an equation that will calculate the cost (y) of x movie tickets in the form of y=rx. The answer is not y=8.5 Please help the one who gives me the correct answer will get brainliest

Answers

The proportional relationship is given by y = 8.5x

Two variables are said to be proportion if an increase/decrease in one variable causes an increase/decrease in the other variable.

Let x represent the movie tickets and y represent the cost.

Since x and y are proportional, hence:

y ∝ x

y = rx

Where r is the constant of proportionality.

From the table to find x, when y = 17, x = 2, hence:

17 = 2r

r = 8,5

y = 8.5x

We then have the equations:
