MARKIN BRAINIEST ANSWER!!!! (btw slide 3 is the answers you might need to solve this)

TiliK225 [7]

Answer:

Step-by-step explanation:

I assume you need help with the first picture:

Let $x=\frac{a}{b} \\y=\frac{c}{d}$

Then

$x+y=\frac{a}{b} +\frac{c}{d} =\frac{ad}{bd} +\frac{bc}{bd} =\frac{ad+bc}{bd} , b,d\neq 0$

Clearly you can see that the sum of 2 rational numbers gives a rational number.

X + 7y = 21 x + 4y = 15 Solve the simultaneous equations

Mariulka [41]

Answer:

x = 7, y = 2

Explanation:

equations given:

x + 7y = 21

x + 4y = 15

make "x" the subject:

x + 7y = 21

x = 21 - 7y .........equation 1

x + 4y = 15

x = 15 - 4y .......equation 2

Solving both the equations simultaneously:

15 - 4y = 21 - 7y

-4y + 7y = 21 - 15

3y = 6

y = 6 ÷ 3

y = 2

If y is 2

Then x = 21 -7y;

x = 21 - 7(2)

x = 21 - 14

x = 7

Donna can fold 400 shirts in an hour. At this rate, how many seconds will she take to fold 120 shirts?

borishaifa [10]

400 shirts in 1 hour, 60 seconds in 1 minute, 60 minutes in 1 hours, so 3600 seconds in an hour.

400/3600 = 120/x

400x= 432,000

x=1080 seconds
