Answer:
40 gallons
Step-by-step explanation:
Let the number of gallons that would completely fill the bathtub be represented by N.
Since 12 gallons of water gives 30% of the number of gallons to fill the bathtub, then;
30% of N = 12
x N = 12
30N = 12 x 100
30N = 1200
divide both sides by 30,
N = 
= 40
The number of gallons that would completely fill the bathtub is 40 gallons.
If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X
Its a half like 1/2 half of a circle or if you have a grid of 100 you would shade 50
Answer:
c=21, d=69, x=37
Step-by-step explanation:
159+c=180
c=21,
21+d=90
d=69,
3x+69=180
3x=111
x=37
Answer:
6 because 6+15=21 and 21+6=27
