Answer:
9,000,000,000 gallons of water.
Step-by-step explanation:
We have been given that a website recommends that you should have 3 gallons of water for every inch of goldfish in your tank. We are asked to find the gallons of water needed for one billion goldfish that are each 3 inches.
First of all, we will find gallons of water needed for each fish.
Now, we will multiply number of gallons of water required for 1 fish by 1 billion to find required gallons of water.
Therefore, you need 9,000,000,000 gallons of water for 1 billion fish.
To figure this out, set up this equation:
180 = 120 + x + x + 16
Simplify: 180 = 136 + 2x
Subtract: 44 = 2x
Divide: x = 22
Answer: x (Angle B) = 22
Hope this helps!! :)
Answer:
4x + y = 13
Step-by-step explanation:
1. Change 4x + y -2=0 into slope intercept form to find the slope:
y = -4x +2 The slope is -4
2. Plug in x, y and m into y = mx + b
-3 = -4 (4) + b
-3 = -16 + b
13 + b
3. Plug m and b into equation y = mx + b
y = -4x + 13
4. Change equation into standard form:
4x - y = 13
Answer:
ST=26
Step-by-step explanation:
RS+ST=RT
17+x+16=4x+3
x+33=4x+3
33-3=4x=x
3x=30
x=30/3
x=10
ST=x+16
ST=10+16
ST=26
