Mathematics
1 answer:
nordsb [41]3 years ago
4 0

Answer:

Step-by-step explanation:

2) x - y = 2/3

         x = \frac{2}{3} + y

3) 3x +2y = 6

          3x = 6 - 2y

Divide the equation by 3

\frac{3x}{3}=\frac{6}{3}-\frac{2y}{3}\\\\x = 2 - \frac{2}{3}y

4)

\frac{1}{4}x + y = 2\\\\ y = 2 - \frac{1}{4}x

5) 4x - 3y = -33

         -3y = -33 - 4x

Divide the equation by (-3)

\frac{-3}{-3}y=\frac{-33}{-3} - \frac{4}{-3}x\\\\ y = 11 + \frac{4}{3}x

1) Yes, it was easy to solve one variable in terms of the other.

2) Yes, it was easy to solve for y in terms of x. Coefficient of x was a fraction.

3) It will be easy if we take the value of x as multiples of 3

Example: if x = 3,

y = 11 + \frac{4}{3}*3 \\\\y = 11 + 4\\\\y = 15

It is easy to plot (3 ,15)

What is the missing value?
Drupady [299]

Answer:

I believe that the missing value is 5, y=5

Step-by-step explanation:

1st since you can see in the ordered pair that 8 is in the x place that means 8 is the x value so what you can do is rewrite the equation to look like this: 5(8)-2y=30

2nd solve for y

5(8)-2y=30

40-2y=30

-40. -40 -subtract 40 on both side

-2y=-10

÷-2. ÷-2 -divide -2 on both sides

y=5

A puppy and a kitten are 180 meters apart when they see each other. The puppy can run at a speed of 25 m/sec, while the kitten c
ser-zykov [4K]

Answer: 36 sec

Step-by-step explanation:

Let

x------> distance the kitten runs before being caught by the puppy

Remember that

The speed is equal to divide the distance by the time

v=d/t

solve for t

t=d/v

so

equate the time

x/20=(180+x)/25

25x=20(180+x)

25x=3,600+20x

25x-20x=3,600

x=3,600/5=720 m

t=d/v=720/20=36 sec

or

t=(720+180)/25=900/25=36 sec
