Answer:
x=10.7
Step-by-step explanation:
Our proportion is
x/4=8/3
We can cross multiply to solve.
This is where you multiply one fraction's numerator with the other fraction's denominator and vice versa.
x*3=4*8
3x=32
Divide both sides by 3.
x=10.6666666667
Round.
x=10.7
Answer:
<em>(x - 7) (x - 3)</em>
Step-by-step explanation:
Did u want the actual answer? Cuz if u do I could do that too, jus lemme kno
20x = 2*100
x = 10 ml (amt of 30% solution needed)
100-x = 90 ml (amt of 10% solution needed)
Very hard but I hope it helps
Answer:
C -16x + 74/5
Step-by-step explanation:
2(x + 7) - 18x + (4/5)
Expand the brackets.
2x + 14 - 18x + (4/5)
Combine like terms.
(2x - 18x) + (14 + (4/5))
-16x + 14 4/5
Convert 14 4/5 to an improper fraction
14 4/5 = ((14 * 5) + 4) / 5 = 74 / 5
Answer = -16x + 74/5
I believe the answer is 4) R, p, N. I hope this helps
