Answer: im guessing you need the amount of compound b
Step-by-step explanation:
1 think out problem
compound A =222m compound B=3 milliliters of compound A used for every 2 milliliters of compound B
write compound B as an equation which is:
a=3+2b
compound a equation is: a=222
to continue you have to make compound B equation equal b
a=3+2b
-2b -2b
a-2b=3
-a -a
-2b/-2=3/-2-a/-2
b= -3/2+a/2
i am working on the substitution method: so now you substitute variables
problems are: b=-3/2+a/2 and a=222
substute a for a: b=-3/2+222/2
b=109.5
a=222
<u>compound A=222</u>
<u>compound B=109.5</u>
<u>add both for final answer or whatever: 109.5+222= 331.5</u>

Answer:
Step-by-step explanation:
5 consecutive multiples of 5....
x , x + 5, x + 10, x + 15, x + 20
the average is 20...
(x + x + 5 x + 10 + x + 15 + x + 20) / 5 = 20
(5x + 50) / 5 = 20
5x + 50 = 20 * 5
5x + 50 = 100
5x = 100 - 50
5x = 50
x = 50/5
x = 10......smallest number
x + 5 = 10 + 5 = 15
x + 10 = 10 + 10 = 20
x + 15 = 10 + 15 = 25
x + 20 = 10 + 20 = 30 <=== largest number
<span>points (6,10)
</span>y = -x
x + y = 0
distance = lax1 + by1 + cl/√(a^2 + b^2)
= l1(6) + 1(10) + 0l/√(1^2 + 1^2)
= l6 + 10 + 0l/√(1 + 1)
= l16l/√2
= 16/√2
= 8 .2/√2
= 8 . √2.√2/√2
= 8√2
Well, you're asking for a refresher on multiplying fractions, but then the
example at the end of your question uses the symbol for division, not
multiplication. So I'll just give you the rules for both operations, and let you
choose the one you need.
To multiply fractions:
-- Multiply the two numerators.
Write the product on top of a new fraction.
-- Multiply the two denominators.
Write the product on the bottom of the new fraction.
-- The new fraction is the product of the two original fractions.
To divide fractions:
-- Invert (flip) the second fraction.
-- Then multiply them.
-- Their product is actually the quotient of the two original fractions.
