12/5 = 2.4 pounds of oranges per person
Step-by-step explanation:
Answer:
30%: 35 liters
50%: 35 liters
Step-by-step explanation:
The desired concentration is halfway between the concentrations of available solutions, so the mixture will be equal amounts of each.
35 liters of 30% acid and 35 liters of 50% acid must be used
_____
If you want to write an equation, it usually works well to let the variable represent the amount of the most concentrated constituent: 50% acid. Then the amount of acid in the final mix is ...
0.50x +0.30(70 -x) = 0.40(70)
0.20x +21 = 28 . . . . simplify
0.20x = 7 . . . . . . . . . subtract 21; next, divide by 0.20
x = 35 . . . . . . amount of 50% solution (liters)
70-x = 35 . . . amount of 30% solution (liters)
Answer:
$6.64
Step-by-step explanation:
To find the answer add all of the values
2.19+1.20+3.25 = 6.64
8x-4=2x-3
One solution was found :
x = 1/6 = 0.167
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
8*x-4-(2*x-3)=0
Step by step solution :
Step 1 :
Solving a Single Variable Equation :
1.1 Solve : 6x-1 = 0
Add 1 to both sides of the equation :
6x = 1
Divide both sides of the equation by 6:
x = 1/6 = 0.167
One solution was found :
x = 1/6 = 0.167
i am not solving for x i am solving for you lol!!!
Juan will jump 40 times in 50 seconds.
The unitary method is a concept wherein a problem is solved first by finding the value of a single unit and then multiplying the single unit value to find the necessary answer.
Here, we are given that
Juan jumps 24 times in 30 seconds
Thus, the number of times he will jump in 1 second is given by-
24/ 30 = 0.8
Thus, he jumps 0.8 times in 1 second
Now, we need to find the number of times he jumps in 50 seconds. We can do so simply by multiplying the number of times he jumps in 1 second by 50.
Thus, number of times he jumps in 50 seconds = 0.8 * 50
= 40
Therefore, Juan jumps 40 times in 50 seconds.
