Given:

CDEF is a rhombus.

To find:

The value of x.

Solution:

We know that the diagonals of a rhombus are angle bisectors because they bisect each vertex angle.

[tex]5x+1=8x-20[/tex]

[tex]5x-8x=-1-20[/tex]

[tex]-3x=-21[/tex]

Divide both sides by -3.

[tex]x=\dfrac{-21}{-3}[/tex]

[tex]x=7[/tex]

Therefore, the value of x is 7.

Answer:

$2.70

Step-by-step explanation:

To add 45 percent to the original price you do 100%+45%=145%=1.45

times 1.45  by the original price.

Then take away the original price from the answer you just got.

$1.45×$6=$8.70

$8.70-$6=$2.70

Answer:

Step-by-step explanation:

Asymptote is the x axis for both functions. the y intercept is translated up to 125

A relation is a function if it has only One y-value for each x-value.

The asymptote and intercept of the given function compare to the asymptote and intercept of the function f(x) = 5ˣ

To find x- or y-intercepts, set the other variable equal to zero and solve in turn.

To find y-intercept: set x = 0 and solve for y. The point will be (0, y). To find x-intercept: set y = 0 and solve for x. The point will be (x, 0).

The asymptote is the x axis for both functions. the y intercept is translated up to 125.

Hence, asymptote is the x axis for both functions. the y intercept is translated up to 125.

Answer:

In technical terms, the slope of the line is the change in y over the change in x. But I just like to think of it as rise overrun. To find the slope of the line, pick two points on the line. Let's say we've looked at our graph, and have picked the points (3, 2) and (5, 6).

Answer:

290 children and 151 adults

Step-by-step explanation:

Given data

let the number of children be x

and the number of adults be y

total number of people= 442

x+y= 442---------1

The daily prices are $1.75 for children and $2.00 for adults. The receipts for admission totaled $811.25

1.75x+2y= 811.25--------2

solve 1 and 2

x+y= 442

1.75x+2y= 811.25

from 1, x= 442-y

put this in 2

1.75(442-y)+2y= 811.25

773.5-1.75y+2y=811.25

collect like terms

773.5+0.25y=811.25

0.25y= 811.25-773.5

0.25y= 37.75

y= 37.75/0.25

y= 151

put y= 151 in 1

x+151= 442

x= 442-152

x= 290

Hence there were 290 children and 151 adults

∘

The measure of ∠T to the nearest degree is 51 degrees

Sine rule is a the used to find the sides and angles of a triangle

Given the following parameters

t = 16 inches,

s = 19 inches

∠S=113°

Required

∠T

According to the rule

t/sin∠T = s/sin∠S

16/sin∠T = 19/sin113

sin∠T = 16sin113/19
sin∠T = 0.775

∠T = 51 degrees

Hence the measure of ∠T to the nearest degree is 51 degrees

Answer:

y = 7, x ≈ 9.9

Step-by-step explanation:

The remaining angle has to also be 45° which tells us we're working with an isosceles right triangle, or that y also has to be 7 (the same length).

Use the Pythagorean theorem for x.

a^2 + b^2 = x^2

7^2 + 7^2 = x^2

49 + 49 = x^2

x^2 = 98

x ≈ 9.9

Answer:

12.96c

Step-by-step explanation:

Given the total cost of an item  written as c+0.08c. To get the total cost of an item that sells for 12, we will write;

1 item = c+0.08c

1 item = 1.08c

For 12items;

12 = x

Divide both expressions

1/12 = 1.08c/x

1 * x = 12 * 1.08c

x= 12.96c

Hence the total cost of 212 items is 12.96c

Answer: x is less than or equal to 29.40

The minimum quantity of paperbacks you must purchase to receive a discount is represented by an inequality where x is less than or equal to 29.40.

A connection that compares two numbers or other mathematical expressions inequitably is known as an inequality in mathematics. On the number line, size comparisons between two numbers are typically conducted.

A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.

Mathematicians utilize the greater than symbol, less than symbol , less than symbol, and not equal to symbol as the five inequality symbols.

Take from each side the same quantity. To both sides, add the same positive number. Add the identical positive value to both sides. Then, multiply both sides by the same negative number while flipping the sign.

Answer:

the second one.... ( 8,9 )

Step-by-step explanation:

the zero-product system is rlly easy to use....

it basically means to take each term and equal it to zero....

so for your equation it is....

( x - 9 ) ( x - 8 ) = 0

so you would write it as....

( x - 9 ) = 0

and

( x - 8 ) = 0

and then you solve them like this...

( x - 9 ) = 0

add 9 to both sides to get the variable by itself...

x= 9

( x - 8 ) = 0

add 8 to both sides to get the variable by itself....

x = 8

Answer:

y=7 and x=-8

Step-by-step explanation:

Isolate x in the first equation:

10x=-17-9y

x=(-17-9y)/10

Substitute into the second equation:

7*((-17-9y)/`10)+10y=14

-119/10+37y/10=14

-119+37y=140

37y=259

y=7

Putting this into the first equation, we get that x=-8
