first roll, and a number greater than 3 the second roll?

Answer:

x=3

Step-by-step explanation:

[tex]\frac{x}{9} =\frac{8}{21+x}[/tex]

x²+21x-72=0

(x-3)(x+24)=0

Answer:

2.72 cm2

Step-by-step explanation:

Height (m) x height (m) =height squared (m exponent 2)

The square of her height in meter² is 2.7225.

To multiply numbers with decimals one way is to multiply the given numbers without the decimal then in the obtained result put the decimal as many places before from the right as the sum of the digits after the digits which those decimal numbers had.

According to the given question Ms. Aluma is 165cm tall.

We know 165 cm is = (165/100)meter = 1.65meter.

As 1 meter is 100 centimeter.

∴ The square of her height is (1.65)² OR (1.65×1.65)m² which is

= 2.7225 m².

Answer:

(-1, -3)

Step-by-step explanation:

What is the ordered pair that satisfies the system 2x - 7y >5 and 3x-y < 4?

Using the coordinate point (-1, 3)

If x = -1 and y = 3

Substitute into the expressions and check if they are true

2x - 7y >5

= 2(-1)-7(-3)

= -2 + 21

= 19

Since 19 is greater than 5, hence the inequality 19 > 5 is true

Substituting into 3x - y < 4

3(-1)-(-3)

= -3 + 3

= 0

Since 0 < 4, hence this is also true for the inequality.

The coordinate point that satisfies the inequality is therefore (-1, -3)

The term "off" indicates that the price of the item is reduced by the percentage off. Sales tax is however, added to the price of the item.

The total cost of the video game console is: [tex]\$476.85[/tex]

Given that:

[tex]Game = \$528[/tex]

15% off means that, the price is reduced by 15%.

So, we have:

[tex]Sales =Game - Game \times 15\%[/tex]

[tex]Sales = \$528 - \$528 \times 15\%[/tex]

[tex]Sales = \$528 -\$79.2[/tex]

[tex]Sales = \$448.8[/tex]

The total cost (when the sales tax of 6.25% is added) is:

[tex]Total = Sales + Sales \times 6.25\%[/tex]

[tex]Total = \$448.8 + \$448.8 \times 6.25\%[/tex]

[tex]Total = \$448.8 + \$28.05[/tex]

[tex]Total = \$476.85[/tex]

Hence, the total cost of the video game console is: [tex]\$476.85[/tex]

Answer:

16=3*2+5x

Step-by-step explanation:

3 is how many notebooks, 2 is cost per notebook, 5 is the cost of binders where x is the amount to bought, and 16 is how much you spent

Answer:

16 = 5x + 6

Step-by-step explanation:

You spend $16 on 3 notebooks and x binders. Notebooks cost $2 each and binders cost $5 each.

From this, we can see that our total amount of money spent is $16. This goes on one side of the equation.

T = 16

You have bought 3 notebooks that cost $2 each. An equation would be

n = 2x with x the number of notebooks bought. Plug 3 into x.

n = 2(3)

n = $6

You spent $6 on notebooks.

Your overall equation will be:

T = 5b + n

T is the total amount of money spent, x is the number of binders purchased, and n is the total amount of money spent on notebooks only.

Plug in the values you know.

16 = 5x + 6

To solve for x, subtract both sides by 6.

16 - 6 = 5x + 6 - 6

10 = 5x

Isolate x further by dividing both sides by 5.

x = 2

You bought 2 binders.

Answer:

The answer is below

Step-by-step explanation:

The question is not complete. The points are not given, but I can explain it.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Dilation is the enlargement or reduction in the size of an object by a factor k. If a line AB is dilated by a factor k, with a center of dilation on the line AB, if the new line formed is A'B', then A'B' would lie on the same line AB irrespective of the dilating factor.

Dilation of a line segment is to smaller or larger a line with a specific scale factor. The line n when dilated with the center of dilation on the line, it will bring no change on the original line.

Given information

The line which is dilated is n.

Dilation of a line segment is to smaller or larger a line with a specific scale factor. If this scale factor is more than 1 then the line segment will larger otherwise smaller.

In the given problem a line n is dilated with the a scale factor that leaves the changed of n.

If the entire line is dilated and the point of this line passes through center of dilation then the change will be nothing. If dilated from the center of dilation the scale factor does not matter.

To find center of dilation which supports Ayako's claim the point below which represents the center of dilation are not given in the problem.

Hence, The line n when dilated with the center of dilation on the line, it will bring no change on the original line.

Answer: 33.3%

Step-by-step explanation:

First find the difference between the players in try-outs over the years.

= 90 - 75

= 25

Then use this difference to find the percent increase:

= Difference / Players last years * 100%

= 25 / 75 * 100%

= 33.3%

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{2}{3}[/tex] x - 6 ← is in slope- intercept form

with slope m = [tex]\frac{2}{3}[/tex]

Parallel lines have equal slopes , then

y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation

To find c substitute (9, 2) into the partial equation

2 = 6 + c ⇒ c = 2 - 6 = - 4

y = [tex]\frac{2}{3}[/tex] x - 4 ← equation of parallel line

-------------------------------------------------------------------

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex] , then

y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

To find c substitute (9, 2) into the partial equation

2 = - [tex]\frac{27}{2}[/tex] + c ⇒ c = 2 + [tex]\frac{27}{2}[/tex] = [tex]\frac{31}{2}[/tex]

y = - [tex]\frac{3}{2}[/tex] x + [tex]\frac{31}{2}[/tex] ← equation of perpendicular line

We have to determine, which is used to compare or determine the relation of a quantity, physical or not, with a certain  numerical value

According to the question,

The process of measurement is required to measure or compare physical quantities in day-to-day life.

Thus, to measure each of the standard quantities, we choose certain units for them that are accepted worldwide.

Other similar quantities can also be expressed in terms of these units and can be measured accordingly.

The physical quantities are measured in terms of the unit and are known as a standard of that physical quantity.

The length of the foot, the width of a finger, and the distance between two different places were commonly measured by different units of measurements.

For unique measurement properties, scientists accepted standard units of measurement all over the world.

Hence, Measurement is used to compare or determine the relation of a quantity, physical or not, with a certain numerical value.
