The sum of three numbers is 123. The third number is 4 times the first. The second number is 9 more than the first. What are the

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

Let the first number = x

Let the second number = x + 9

Let the third number = 4x

Together they make 123

x + x + 9 + 4x = 123 combine the left

6x + 9 = 123 Subtract 9 from both sides

6x = 123 - 9

6x = 114 Divide by 6

x = 114/6

x = 19

=================

First number = 19

Second number = 19 + 9 = 28

Third number = 4*19 = 76

Please solve this literal equation for the variable "f"

Tatiana [17]

$\frac{df+10}{6}= g$

Now, multiply both sides by 6 and you get.....

df+10=6g

now, subtract 10 on both sides and you get.....

df=6g-10

now divide both sides by d to get f by itself and you get........

$f= \frac{6g-10}{d}$
