Answer:

x=2.65

Step-by-step explanation:

First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

[tex]4x-5*2.5=14[/tex]

This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:

[tex]4x-5=5.6[/tex]

Next, add 5 to both sides:

[tex]4x=10.6[/tex]

Then divide both sides by 4:

[tex]x=2.65[/tex]

Step-by-step explanation:

Answer:

A): 22/5 = 4 2/5 in mixed fraction. 22/5 = 4.4 in decimal. B): 0.875

Step-by-step explanation:

Since you can't divide 7/8 it will turn into decimal. If you use calculator, it will be decimal. Basically in order to do long division, you would need to drop down zeros like add zeros if the divisor and dividend don't equal. You keep adding zeros until it's equal. IF it is more likely to be continuous, then you would need to add a repetend on the last digit. For example, 3/1 you can know it would be 1.333333 and so on. Example of how to do it:

4 cups is precisely 32 fluid ounces.

Answer:

4 cups = 32 fluid ounces.

Step-by-step explanation:

The equation for converting cups to ounces is x8, so 4 cups times 8 equals 32 fluid ounces. Hope this helps!!

Answer:

5%

Step-by-step explanation:

Solving our equation

r = 75 / ( 750 × 2 ) = 0.05

r = 0.05

converting r decimal to a percentage

R = 0.05 * 100 = 5%/year

The interest rate required to

accumulate simple interest of $ 75.00

from a principal of $ 750.00

over 2 years is 5% per year.

Answer:

11 months

788 disc

Step-by-step explanation:

Let

x = number of months

Fry's Electronics;

= 920 - 12x

Blu-ray discs:

= 502 + 26x

Equate both equations

920 - 12x = 502 + 26x

920 - 502 = 26x + 12x

418 = 38x

x = 418/38

x = 11 months

number of months = 11

Substitute 11 into any of the equation

Fry's Electronics;

= 920 - 12x

= 920 - 12(11)

= 920 - 132

= 788 disc sold in that months

[tex] x = \sqrt 5[/tex]

Step-by-step explanation:

On solving by Pythagoras theorem:

(Going in counterclockwise direction)

For bottom most triangle :

Length of Hypotenuse [tex] = \sqrt {1^2 +1^2} =\sqrt {1+1}=\sqrt 2[/tex]

The for second triangle :

Length of Hypotenuse [tex] = \sqrt {(\sqrt 2) ^2 +1^2} =\sqrt {2+1}=\sqrt 3[/tex]

The for third triangle :

Length of Hypotenuse [tex] = \sqrt {(\sqrt 3) ^2 +1^2} =\sqrt {3+1}=\sqrt 4 = 2[/tex]

The for fourth triangle :

x [tex] = \sqrt {(2) ^2 +1^2} =\sqrt {4+1}=\sqrt 5 [/tex]

The x value for the given partial spiral is √5 units.

We need to solve for x in the partial spiral given.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

From the right triangle 1:

Let the hypotenuse be a.

So, a²=1²+1²

⇒a=√2

From the right triangle 2:

Let the hypotenuse be b.

So, b²=(√2)²+1²

⇒b=√3

From the right triangle 3:

Let the hypotenuse be c.

So, c²=(√3)²+1²

⇒b=√4=2

From the right triangle 2:

The hypotenuse=x

So, x²=2²+1²

⇒x=√5

Therefore, the x value for the given partial spiral is √5 units.

Answer:

x=19

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x+7=3(x−4)

2x+7=3(x−4)

2x+7=(3)(x)+(3)(−4)(Distribute)

2x+7=3x+−12

2x+7=3x−12

Step 2: Subtract 3x from both sides.

2x+7−3x=3x−12−3x

−x+7=−12

Step 3: Subtract 7 from both sides.

−x+7−7=−12−7

−x=−19

Step-by-step explanation:

When the product of the slopes of two lines is -1.

The lines are perpendicular.

When the product of the slopes of two lines is 1.

The lines are on the same line.

When the slopes of two lines are the same.

The lines are parallel.

slope of AB x slope of CD = 1

The lines are on the same line.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A (3,5), B(−2,7), C(10,5), D(6,15).

When the product of the slopes of two lines is -1.

The lines are perpendicular.

When the product of the slopes of two lines is 1.

The lines are on the same line.

When the slopes of two lines are the same.

The lines are parallel.

The line AB.

Slope = (7 - 5) / (-2 - 3) = 2 / -5 = -2/5

The line CD.

Slope = (15 - 5) / (6 - 10) = 10 / -4 = -5/2

Now,

slope of AB x slope of CD.

= -2/5 x -5/2

= 1

This means,

The lines are on the same line.

Thus,

slope of AB x slope of CD = 1

The lines are on the same line.

Answer:

Step-by-step explanation:

point-slope equation of the line: y+1 = -(x-3)

rearrange to solve for y:

y+1 = -x+3

y = -x + 2   slope-intercept form

Answer:

y = -x + 2

Step-by-step explanation:

We are given that a line has a slope of -1 and passes through the point (3, -1)

We want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept

As we are already given the slope, we can immediately plug its value into y=mx+b.

Replace m with -1 in y=mx+b.

y = -x + b (there's no need to write -1 in front of x. If -1 is the coefficient in front of a variable, just writing a minus sign in front of the variable is enough).

Now we need to find b.

As the equation passes through the point (3, -1), we can use it to help solve for b.

Substitute 3 as x and -1 as y.

-1 = -3 + b
Add 3 to both sides

2 = b

Substitute 2 as b in the equation so far.

y = -x + 2
