Step 1
Write out the system of equations
Step 2
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
It would be D. Since X=2 in the beginning, and and is 8 in the end. 2*4 is 8.
So, -5 times four would be 20, but not in this context. it would be -20.
We use ratios to make comparisons between two things. When we express ratios in words, we use the word "to"--we say "the ratio of something to something else." Ratios can be written in several different ways: as a fraction, using the word "to", or with a colon.
<span>Let's use this illustration of shapes to learn more about ratios. How can we write the ratio of squares to circles, or 3 to 6? The most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number. </span>
X equals 0,4.........................
