Tomtit [17]

In this case we can make a proportion.

$\frac{8 \: jokes}{75 \: mins} = \frac{x \: jokes}{1200 \: mins}$
Now cross multiply.

9600 = 75x

Divide both sides by 75.

X=128

He will make 128 jokes in 1200 mins.

The sum of two numbers is 18. 5 times the first number subtracted from 4/7 of the second number is 14. Find the number.

Sergeu [11.5K]

Answer:

The sum of two numbers is 18.

5 times the first number subtracted from 4/7 of the second number is 14.

First number --> x

Second number --> y

x + y = 18 --> x = 18-y

5x - (4/7)y = 14

5 (18-y) - (4/7)y = 14

90 - 5y - 4/7 y = 14

-5.57 y = 14-90

y = 13.64

x = 18 - 13.64

x = 4.36
