Ok so 1st, you do the (80 ÷ 20), then you get
10-4+(4)y^4
then you 10-4
6+(4)y^4
then....
(10)y^4
so then it's
10y^4
Unless there is a =, but if not it's 10y^4
Graph is attached to this answer!
It is a linear simple equation, lets solve it step by step:
<span>X + 3(X + 4) = 20
x + 3x + 3*4 = 20
4x + 12 = 20
4x = 20 - 12
4x = 8
x = 8/4
x = 2</span>
50/2.5=
20
Unit rate is 20 miles per gallon
Answer:
- 35 grams of 11.43% solution
Step-by-step explanation:
The end solution has same volume as initial volumes of mixture.
The concentration of solution is calculated as below
- 10*0.15 + 25*0.1 = 4 g
- 4 / 35*100% = 11.43% (rounded)
