Answer:
Step-by-step explanation:
1. 2 + 3{(4 - 1)2}
let solve the bracket first
2+3{(3)2}
2+3(9)
2 + 27
=29
2. 3y - ( x +2)
where x = -5 and y = 3
3(3) - (-5 + 2)
9 + 5 - 2
i multiply the bracket with negative sign
9 + 3
= 12
3. 2(4x - 3) + 3x
distribute
8x - 6 + 3x
combine the like terms
8x + 3x -6
Answer:
60 liters of 20% solution & 20 liters of 60% solution
Step-by-step explanation:
80*0.3=.2x+0.6(80-x)
24=0.2x+48-0.6x
-24=0.2x-0.6x
-24=0.4x
24=0.4x
60=x
Hope this helps!! This is step by step btw!
Answer:
