Find the area of the shape. 8

Answer:

A and C

Step-by-step explanation:

A) 160 + 20 = 180

B) 120 + 40 = 160

C) 45 + 135 = 180

D) 30 + 120 = 150

All supplementary angles must add up to 180 degrees.

Answer:

B

Step-by-step explanation:

The lines marked with ||| are equal. That means that 2P + 7 equals 17

2P + 7 = 17                    Subtract 7 from both sides.

2P + 7 - 7 = 17 - 7         Combine

2P = 10                         Divide by 2  

P = 5

3k - 5 and 28 are marked with one | That means that they are equal

3k - 5 = 28

3k = 28 + 5

3k = 33

k = 33/3

k = 11

The answer is B

Answer:

Number 4 is neither, number 6 is perpendicular

Step-by-step explanation:

Answer:

4) Neither

Same y intercept means intersecting and intersecting is not an option

6) Perpedicular

A perpendicular line has a slope the reciprocal of each other like in this case

0.4= 2/5, 5/2=2.5

Answer:

5. 216, 1416

6. 448.5 g

Step-by-step explanation:

5.

Price of 1 item: 1200

GST = 18%

18% of 1200 =

= 0.18 * 1200

= 216

Amount of tax: 216

Total price = original price + GST

Total price = 1200 + 216 = 1416

6.

Weight of 1 item: 17 1/4 g

Weight of 26 items = 26 * 17 1/4 g

26 * 17.25 g = 448.5 g

Answer:

just divide 1/5 by 100 and you should get it

Step-by-step explanation:

Answer:

La situación está representada por el siguiente sistema:

[tex]y = 20+2\cdot x[/tex]

[tex]y \ge 50[/tex]

Donde:

[tex]x[/tex] - Cantidad de rosas vendidas semanalmente.

[tex]y[/tex] - Ganancia semanal, medida en dólares.

Step-by-step explanation:

De acuerdo con el enunciado, Nita gana una cantidad fija cada semana por pasear al perro de su vecino, con un monto de $ 20, mientras que gana en función de la cantidad de rosas a vender, con un valor unitario de $ 2. Si ella desea ganar al menos $ 50, por tanto, se requiere construir el siguiente sistema, conformado por una ecuación y una inecuación:

[tex]y = 20+2\cdot x[/tex] (1)

[tex]y \ge 50[/tex] (2)

Donde:

[tex]x[/tex] - Cantidad de rosas vendidas semanalmente.

[tex]y[/tex] - Ganancia semanal, medida en dólares.

Answer:

X=4

Step-by-step explanation:

4(x+12) = 19x-12

4x+48= 19x-12

sub 4x from both sides

48= 15x-12

add 12 to both sides

60=15x

divide 15 from both sides

and 60/15 =4

Answer:

[tex]4(x + 12) = 19x - 12 \\ 4x + 48 = 19x - 12 \\ 4x - 19x = - 12 - 48 \\ - 15x = - 60 \\ x = \frac{60}{15} \\ x = 4[/tex]

Answer:

(3,-9)

Step-by-step explanation:

The given equations are :

−5x−3y=12 (1)

y=x−12 ....(2)

Put the value of y from equation (2) in equation (1)

−5x−3(x-12)=12

-5x-3x+36 = 12

Taking like terms together

-5x-3x = 12-36

-8x = -24

x = 3

Put the value of x in equation (2)

y=3−12

y = -9

Hence, the solution of the above equations is x = 3 and y = -9 or (3,-9).

Answer:

x=−3 or x=5

so yeah

Answer:

one pound of apple cost $2.5

Step-by-step explanation:

Let the amount they both spent at the grocery store be y and x be the price of apples per pound.

Since Tara bought 5 pounds of apples, 5x = y (1) and Ashley bought 3 pounds of apples and $5 worth other groceries, 3x + 5 = y (2).

Equating both expressions, 5x = 3x + 5

collecting like terms,

5x - 3x = 5

2x = 5

dividing both sides by 2, we have

x = 5/2

x = 2.5

So one pound of apple cost $2.5

Answer:

5/12

Step-by-step explanation:

of means multiplication. so multiply 5x2 / 6x2 which is 5/12

Answer:

A. 5/12

Step-by-step explanation:

the "of" in the answer is asking you to multiply.

what you want to do is multiply the numerators and denominators.

5 x 1 = 5

6 x 2= 12

giving you 5/12!

Answer: 19nickels and 7dimes.

Ps i really don’t know where the 50.05 came from if it is suppose to be there then I really don’t know how to solve this.

Step-by-step explanation:

Ok so if you know that there are 19nickels, let n=number of nickels.

The number of total coins subtracted by number of nickels will give you number of dimes.

165-number of nickels=number of dimes

Value of dimes=10(number of dimes) or total value of dimes/individual value (10cent)

Then you can substitute total as $1.65 and get the value of nickels by multiplying by 5cent ( my teacher taught me using whole numbers to make it easier so I turned $1.65 to 165 cent). Since the value of the dimes is the value of nickels subtracted from the total, I can subtract 95 from 165 and divide the difference by 10, to get the number of dimes.

5(n)=5(19)=95

(165-95)/10=number of dimes

70/10=7dimes

You can check by multiplying 7x10 and 5x15 again and adding them together to see if they equal 165 cent.

Answer:

if you're looking for the value of x, I'm guessing it's 11

Answer:

x=7; y=21

Step-by-step explanation:

These angles are congruent so:

7y-3=2x+4

We need to find x, and AB and DC are congruent, so:

3x+3=6x-18

Add 18 to both sides:

3x+21=6x

Subtract 3x from both sides:

3x=21

Divide by 3:

x=7

Substitute:

7y-3=2(7)+4

Simplify Like-Terms:

7y-3=18

Add 3 to both sides:

7y=21

Divide both sides by 7:

y=21

Answer:

Let x be the number

"five times a number"

5x

"six less than five times a number"

5x-6

"is at least 29" >29 (greater than or equal too)

5x - 6 > 29

5x > 35 (add +6 to both sides retains the dense if the inequality)

x>7 (divide both sides by +7 retains the sense of Inequailty)

Check:

Is 5(7) - 6 > 29?

35 - 6 > 29 ?

29 > 29? yes, they are equal.

Try 50:

Is 5(50) - 6 > 29 ?

250 - 6 > 29?

244 > 29 ? yes

Answer:

5x - 6 = 29
