Answer:
They should add gallons of the store-bought lemonade.
Step-by-step explanation:
Given that,
Two friends make 2 gallons of lemonade containing 30% lemon juice.
The amount of lemon juice in 2 gallons of lemonade is
= 30% of 2 gallons
gallons
Let they added x gallons of store-bought lemonade that contains 20% lemon juice.
The amount of lemon juice in x gallons of lemonade is
= 20% of x gallons
gallons
Now the total amount of lemon juice in the mixture is
gallons
gallons
Total amount of lemonade is = (2+x) gallons.
The percentage of lemon juice in the lemonade is
According to the problem,
⇒ 60+20x= 23(2+x)
⇒60+20x= 46+23x
⇒23x-20x= 60-46
⇒3x=14
gallon
They should add gallons of the store-bought lemonade.
Answer:
Hello! answer: 29.5
Step-by-step explanation:
To find area for rectangles you just do base × height our base being 5.9 and our height being 5 now we just multiply these together so 5.9 × 5 = 29.5 so 29.5 is the area hope this helps!
To calculate the slope containing two points, we can use that formula:
"m" represents the slope and coordinates are expressed as follows: (x, y)
Let's go to the calculations.
The answer is -0.75.
Answer:
x = 7/2
Step-by-step explanation:
Solve for x over the real numbers:
(3 x - 2) (x + 4) - 3 (x + 5) (x - 1) = 0
Expand out terms of the left hand side:
7 - 2 x = 0
Multiply both sides by -1:
2 x - 7 = 0
Add 7 to both sides:
2 x = 7
Divide both sides by 2:
Answer: x = 7/2
