El Punto 22, Los Resultados/procedimiento Para Confirmar Que Lo Hice Bien

Answers

Answer 1

Answer:

a)

1/4 : a = 1/10

1/4 = a*1/10

(1/4) : (1/10) = a

(1*10):(4*1) = a

10/4 = a

entonces:

1/4 : 10/4 = 1/10

respuesta:

en el recuadro va:

10/4 o su equivalente 2/5

b)

3/7 : a = 9

(3/7) : 9 = a

3 : (7*9) = a

3 / 63 = a

entonces:

(3/7) : (3/63) = 9

(3*63) : (7*3) = 9

63 : 7 = 9

entonces, en el recuadro va:

3/63 o su equivalente 1/21

c

a : (1/2) = 5/2

a = (5/2) * (1/2)

a = (5*1) / (2*2)

a = 5/4

entonces:

(5/4) : (1/2) = 5/2

(5*2) : (4*1) = 10/4 = 5/2

entonces, en el recuadro va:

5/4

d

a : (1/2) = 2/5

a = (2/5) * (1/2)

a = (2*1) / (5*2)

a = 1/5

entonces:

(1/5) : (1/2) = 2/5

(1*2) / (5*1) = 2/5

Solve the system of linear equation. 2x-5= 14
3x+2y = 40

Answers

Answer:

x=9.5, y=5.75

Step-by-step explanation:

2x-5=14, 3x+2y=40

focus on 2x-5=14 first:

2x-5=14 (add 5 to both sides) 2x=19(divide both sides by 2) x=9.5

Now subtitute x into the second equation and find y:

3(9.5)+2y=40(simplify) 28.5+2y=40(subtract 28.5 on both sides) 2y=11.5(divide both sides by 2) y=5.75

X=9.5, Y=5.75. Step by Step Explanation is-
First take 2x-5=14
= 2x=14+5 ; 2x=19 ; x=19/2=9.5
Now take 3x+2y=40; We substitute the value of x with 9.5. So the equation is-
=3*9.5+2y=40 ; 2y+28.5=40 ; 2y=40-28.5=11.5 ; y=11.5/2=5.75.
Thank you and hope it helped

Kyle has $25 and gets a job walking Chihuahuas for $2 per hour. Sophia has $4 and walks Rottweilers for $9 per hour. How many hours will they both have to work to have the same amount of money?

Answers

Answer:

  3 hours

Step-by-step explanation:

Let k represent Kyle's balance after h hours. Let s represent Sophia's balance after h hours. Then we have ...

  k = 25 +2h

  s = 4 +9h

We want to find h so that k=s:

  25 +2h = 4 +9h

  21 = 7h . . . . . subtract 4+2h

  3 = h . . . . . . . divide by 7

If both work 3 hours, they will have the same amount of money.

Answers

Percents is a number out of 100. So basically what you’re going to do here is add up the percents. 40+20+10. Add that up and you get 70. You then subtract 70 from 100. You get 30. So the percentage of red pens is 30%.

Answers

Step-by-step explanation:

2x + 1 + x - 13 = 180° because these angles are supplementary

3x - 12 = 180°

3x = 180 + 12

3x = 192 divide both sides by 3

x = 64

2x + 1 ➡ 2 × 64 + 1 = 129°

x - 13 ➡ 64 - 13 = 51°
