Convert 9.500 to a fraction

Answer:

x = -10

y = 20

Step-by-step explanation:

y = -2x

so

substituting the value in equation ii

3x + 4y = 50

or, 3x + 4(-2x) = 50

or, 3x + (-8x) = 50

or, 3x-8x = 50

or, -5x = 50

so, x = -10

so

y = -2x

or, y = -2*(-10)

so, y = 20

Answer:

13

Step-by-step explanation:

13 x 13 = 169

The distance between the two points (7, - 1) and (9, - 9) is,

d = √68

We have to given that,

To find the distance between the two points (7, - 1) and (9, - 9)

Since, The distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, We get;

The distance between the two points (7, - 1) and (9, - 9) are,

d = √ (9 - 7)² + (- 9 + 1)²

d = √4 + 64

d = √68

Therefore, the distance between the two points (7, - 1) and (9, - 9) is,

d = √68

a) 20(x)=y

b) $120

Let x= number of hours

Let y= Cost of labor

20 will remain constant, what matters is how many hours are being worked. If it's $20 per hour then it's safe to assume 1 hour is 20 dollars worth of labor. Due to it being per hour you have to multiply the rate by however many hours worked to get your final cost.

Answer:

B.

Step-by-step explanation:

Answer:

5.25inches

Step-by-step explanation:

difference in height = 68.5-63.25 =5.25

Height of Mario Hm = 68.5 inches

Height of Tyler Ht = 63.25 inches

Evidently, Hm > Ht

Now difference = Hm - Ht = 68.5 - 63.25

= 5.25 inches

Answer: Mario is 5.25 inches taller than Tyler.

Answer:

first angle is 20, 2nd is 120, 3rd is 40.

Step-by-step explanation:

with these words, "20 less than a number, Three

times the number, is the number." We can set up the equation x-20+3x+x = 180. combine like terms and we get 5x-20=180. add 20 to both sides to get 5x=200 then divide 200 by 5x to get x = 40. We can then plug 40 into each of the expressions, x-20, 3x, x, to get our angles.

Answer:

right angled triangles

-9 - 9 is the same that -9 + (-9)

Answer:

I confirm my answer : 8(cm)

Step-by-step explanation:

In the triangle OAB, BO²=AB²+AO²-2*AB*AO*cos( BAC)

cos (BAC)=9²+17²-10²/(2*9*17)=15/17

AC/AO=cos(BAC) ==> AC=17*15/17=15

OC²=AO²-AC²=17²-15²=64

OC=8 (cm)

Transformation involves changing the position and/or dimension of a shape, a line or a point.

I've added as an attachment, the result of the transformation.

From the question, the following transformations were performed by Diego.

Move downward ----- > Turn 90 degrees clockwise ----- > Move to the right

Move downward

When a shape is moved downward, the new position of the shape will be directly under its previous location

Turn 90 degrees clockwise

This means that the shape will be rotated, 90 degrees to the right. However, the position of the shape will remain unchanged.

Move rightward

When a shape is moved rightward, the new position of the shape will be directly to the right of its previous location

The expressions are evaluated using distributive property below -

We have -

i. 425 x 136

ii. 4005 x 67

We have to evaluate them with help of distributive property.

Distributive property of multiplication over addition :  

a × (b + c) = a × b + a × c

According to question, we have -

i. 425 x 136

ii. 4005 x 67

Now -

425 x 136 = 425 x (6 + 30 + 100) = 425 x 6 + 425 x 30 x 425 x 100

and

4005 x 67 = 4005 x (60 + 7) = 4005 x 60 + 4005 x 7

Hence, the evaluation using distributive property is done.
