Answer:
We will need 27/31 of an ounce of red
Step-by-step explanation:
3 /10 red + 11 /15 blue makes 1 1/30 purple
Get a common denominator of 30
3/10 * 3/3 = 9/30 red
11/15 *2/2 = 22/ 30 blue
1 1/30 = 31/30 purple
So the ratio of red to purple is
9/30
-------- = 9/ 31
31/30
Keeping this ratio, we want 3 ounces purple
9 red x red
-------- = --------------
31 purple 3 purple
Using cross products,
9*3 = 31 *x
27 = 31x
Divide each side by 31
27/31 = x
We will need 27/31 of an ounce of red
Looks like <CXB and <BXA are congruent
Answer:
x=20
Step-by-step explanation:
2(x+10)=60
distribute 2 by multiplying numbers in parenthesis
2x+20=60
subtract 20 from both sides
2x=40
divide both sides by 2
----------
x=20
