Answer:
1.5gal
Step-by-step explanation:
From the given information:
50% lemon juice + 50% lime juice is the intended mixture.
Therefore, to find quantity that would be added to 20% lemon juice and 80% lime juice, let's assume this to be x.
x of 100% and 4-x gallons of the existing 20% mix
100%x + 20%(4-x) = 50%(4)
1.00x + 0.2(4-x) = 0.5(4)
1.00x + 0.8-0.2x = 2
1.00x-0.2x = 2-0.8
0.8x = 1.2
× = 1.5gal.
Answer:
number a is correct answer
A. c <= -4 so is the top graph;
b. c > 4 so is the second graph;
c. c < 10 so will be a graph with an open circle starting at 10 and going left towards negative infinity
Input that equation into math weigh dot com except weigh is spelled way it just won’t let me type it out on here. and choose graph its a life saver
Answer:
The number is 9.
Step-by-step explanation:
Lets write this as an equation first. We'll substitute the number for the variable <em>x</em>.
80 - 3x = 5x + 8
First, let's add 3x to both sides.
80 - 3x + 3x = 5x + 3x + 8
80 = 8x + 8
Next, let's subtract 8 from both sides.
80 - 8 = 8x + 8 - 8
72 = 8x
Finally, let's divide both sides by 8.
72/8 = 8x/8
9 = x
<em>"x" is 9.</em>
<em>So the secret number is 9.</em>
