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:
( -1,-2)
Step-by-step explanation:
x + y = -3
x - y = 1
Add the two equations together to eliminate y
x + y = -3
x - y = 1
------------------
2x = -2
Divide by 2
2x/2 = -2/2
x = -1
Now find y
x+y =-3
-1 +y = -3
-1+1 +y = -3+1
y = -2
( -1,-2)
Answer:
5
Step-by-step explanation:
6a = (a*-3) + 45
then:
6a = -3a + 45
6a + 3a = 45
9a = 45
a = 45/9
a = 5
Check:
6*5 = (5*-3) + 45
30 = -15 + 45
