Answer:8 cup servings. 1/4×8=8/4
Step-by-step explanation:
1
is the right answer.
because rise is 1 and run is 1 = 1/1 = 1
Answer:
1/3
Step-by-step explanation:
There are 6 possible outcomes when rolling 1 die
1,2,3,4,5,6
P ( 1 or 5) = number of times 1 or 5 happens / total outcomes
= 2/ 6
= 1/3
Answer:
No because upon subtracting x on both sides you obtain a false equation of 4=8.
The problem:
What are x values that satisfy:
x+4=x+8?
Step-by-step explanation:
No number can be substituted into x+4=x+8 to make it true.
There is no number that you can find such that when you add 4 to it will give you the same as adding 8 to it.
Also if you subtract x on both sides you obtain the equation 4=8.
4=8 is not true so x+4=x+8 is never true for any x.
Solving a system of equations we will see that we need to use <u>40 liters of the 80% acid solution</u>, and the other <u>20 liters are of the 35% acid solution</u>.
<h3>
How many liters of each solution do we need to use?</h3>
First, we need to define the variables:
- x = liters of the 35% acid used.
- y = liters of the 80% acid used.
We know that we want to produce 60 liters of 65% acid, then we have the system of equations:
x + y = 60
x*0.35 + y*0.80 = 60*0.65
(in the second equation we wrote the percentages in decimal form).
To solve this we need to isolate one of the variables in one equation and then replace it in other one, isolating x we get:
x = 60 - y
Replacing that in the other equation:
(60 - y)*0.35 + y*0.80 = 60*0.65
y*(0.80 - 0.35) = 60*(0.65 - 0.35)
y*0.45 = 60*0.30
y = 60*0.30/0.45 = 40
So we need to use <u>40 liters of the 80% acid solution</u>, and the other <u>20 liters are of the 35% acid solution</u>.
