Find the value of one pound of type A coffee, x
Therefore the answer will be;
The pounds of type B coffee she used is 64pounds
The pounds of type A coffee she used is 84 pounds
Answer:
-2 ≥ b
Step-by-step explanation:
10 ≤ -2 ( 9 + 12b ) / 3
10 ≤ -2 ( 3 + 4b )
-10 ≥ 2 ( 3 + 4b )
-10 ≥ 6 + 8b
-16 ≥ 8b
-2 ≥ b
So the first thing you are going to want to do is isolate the x variable onto one side.
To do that you want to add 1/10 to each side since there is a -1/10 on the side with the 4/5x.
That will leave you with 4/5x=4/10.
The next thing you want to do is get rid of the fraction with the x. To do that you will need to multiply each side with the reciprocal of 4/5. The reciprocal is the reverse of the fraction. In this case that would be 5/4.
Your equation would look like this 5/4*4/5x=4/10*5/4
After you simplify that it leaves you with x=1/2.
Your final answer is x=1/2.
