Given that,
To find the values of x and y. State which theorem(s) you used.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Vertical opposite angles

3x = 5x - 64
2x = 64
x = 32

Now,

5x - 64 = 5*32 - 64
            = 160 - 64

            = 96°
Now complementary angle y
y = 180 - 96°

y = 84°


Thus, the required simplified value of x and y is 32 and 84 respectively.

Find x and the measure of each side.
Δ F G H is an equilateral triangle with F G=3 x-10, G H=2 x+5 , and H F=x+20 .

Answers

For given equilateral triangle ΔFGH, x = 15. And the measure of each side is 35 units.

In given question,

ΔFGH is equilateral triangle.

The sides of ΔFGH are:

FG = 3x - 10,  

GH =2x + 5 ,

and HF = x + 20 .

We need to find the value of x.

Since ΔFGH is an equilateral triangle, FG = GH = FH

⇒  3x - 10 = 2x + 5 = x + 20

Consider  3x - 10 = 2x + 5

⇒ 3x - 2x = 5 + 10

⇒ x = 15

Now we find the measure of each side.

FG = 3x - 10

FG = 3(15) - 10

FG = 35 units

But FG = GH = FH

So, the measure of each side is 35 units.

Therefore, for given equilateral triangle ΔFGH, x = 15. And the measure of each side is 35 units.

Find the slope of the line through each pair of points. 3/2 , - (1/2) and -(2/3) , 1/3

Answers

The slope of the line of each pair of points 3/2 , - (1/2) and -(2/3) , 1/3 is zero

What is a slope of line?

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x.

We also refer to this tan as the line's slope.

We know that slope, slope = m =  [tex]\frac{y_2 -y_1}{x_2 -x_1}[/tex]

For the pair of points 3/2 , - (1/2)

m = [tex]\frac{2-2}{-1-3}[/tex]

   = 0/(-4)

Hence the slope is zero for these points.

For the pair of points -(2/3) , 1/3

m = [tex]\frac{3-3}{1-(-2)}[/tex]

   = 0/3

Hence the slope is zero for these points.

(a) Taro costs $7.00 per kilogram.
What is the cost of a taro that weighs 510 grams?
$2.83
$3.57
$4.28
$5.10
(b) A taro costs $4.20. What is the weight of the taro in grams (g)?

Answers

Answer: a) $3.57   b) 600 g

Step-by-step explanation:

a)  1 kg=1000g

Let's do the proportion:

$7.00 - 1000 g

  $x    -  510 g

Hence,

[tex]\displaystyle\\x=\frac{7*510}{1000} \\\\x=\frac{3570}{1000} \\\\x=3.57\ dollars[/tex]

b)  

Let's do the proportion:

$7.00 - 1000 g

$4.20 -    x g

Hence,

[tex]\displaystyle\\x=\frac{4.2*1000}{7} \\\\x=\frac{4200}{7} \\\\x=600 g[/tex]

a) The cost of a taro that weighs 510 grams is, $3.57

b) The weight of the taro in grams (g) is, 600 g

a) Here, Taro costs $7.00 per kilogram.

Hence, the cost of a taro that weighs 510 grams is,

= 1000 grams = $7.00

510 grams = $7.00 x 510 / 1000

                = $3.57

Hence, the cost of a taro that weighs 510 grams is, $3.57

b) Since, A taro costs $4.20

Now, WE can change the weight of the taro in grams (g) as,

$7.00 = 1000 g

Hence, $4.2 = 1000 x $4.2 / 7

                    = 600 grams

What are sequences?

 A sequence is defined by an order of values and/or elements that have a relationship of variation as a ratio or proportion that makes them predictable.

 The first thing to do in this problem is to compare the behavior of the first three trials (variation between each number):

75, 79, 83

83 - 79 = 479 - 75 = 4

   We must find an expression that models a variable behavior of 4 starting at 75

An = A1 + (n - 1)x : Where x = 4

Fourth proof:

A(4) = 75 + (4 - 1)4

A(4) = 87

Fifth test:

A(5) = 75 + (5 - 1)4

A(5) = 91

After four seconds, the rock will have dropped -20 inches.

Because Lisa's hand is five feet above the water's surface, we need to add five to the distance between her hand and the rock in order to calculate how far away it is.

Since Line AT bisects ∠CAR

m∠CAR = 2 × m∠CAT

9x + 7 = 2( 5x )

We solve for x

9x + 7 = 10x

10x - 9x = 7

x = 7

We know that a bisector divides a line or angle into two equal halves.

Hence, m∠CAT = m∠TAR

m∠TAR = m∠CAT = 5x

m∠TAR = m∠CAT = 5(7)

m∠TAR = m∠CAT = 35°

a+b+c =900

b=c-50

a=50+c

i then plug the a and b equation into the first one to get

50+c+c-50+c=900

The fifties cancel out, so we are left with 3c =900 so c=300

From this we can figure out the rest by substituting in 300 for c in the an and b equations.
300-50=250
