To solve this problem, let's set up a proportion, letting x represent the unknown number of gallons the faucet loses in 48 hours.
5 gallons / 20 hours = x gallons / 48 hours
To solve this proportion, we are going to use cross-products. This is the products of numerator of one fraction and the denominator of the other fraction set equal to one another. It results in the equation:
5 * 48 = 20 * x
Next we simplify by performing the operations.
240 = 20x
Finally, we divide both sides by 20 to get x alone on the right side of the equation.
12=x
Therefore, 12 gallons of water will be lost in 48 hours.
If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.
Let x be the number of ml you need.
Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg
(1 ml)/(1 mg) = (x ml)/(0.1 mg)
Cross multiply.
1 * x = 1 * 0.1
x = 0.1
Answer: 0.1 ml
8x - 2(x + 1) = 2(3x - 1)
First, expand to remove parenthesis. / Your problem should look like:
Second, subtract 8x - 2x - 2 to get 6x - 2. / Your problem should look like:
Third, both sides are equal, so there are infinite solutions. The equation is always true.
Answer:
infinite solutions
Answer:
(1,4) (1,0)
Step-by-step explanation:
THis is because they are on the same x axis this means they will overlap wheras if they were on the y and the x was differnt they wouldnt overlap
The answer is 1/40. You find it by substituting the variables for their corresponding numbers then solve. ((-3) + 2(2))/10(4)
