Answer:
x = 15
Step-by-step explanation:
Sides opposite congruent angles are congruent:
x + 10 = 2x - 5
15 = x . . . . . . . . . add 5-x
The value of x is 15.
_____
I suppose you could show the intermediate step:
x +10 +(5 -x) = 2x -5 +(5 -x)
15 = x . . . . . simplified
Answer:
-2x²+3x-6=0
Step-by-step explanation:
If it's quadratic :
Solution ax²+bx+c=0
-2x²+3x-6=0
Answer:
n=40
Step-by-step explanation:
divide 32 by 80
32/80=0.4
0.4x100=40
n=40
Answer:10 liter * 20%= x liter*40% + (10- x) liter*5%
10l * 20%= x liter * 35% + 10 liter*5%
x liter *35 = 10l * 20 - 10l *5= 10l*15
x liter = 10l *15/35= 4.28 L= 4.3L
The volume of 40% solution= 4.3L
The volume of 5% solution= 10L- 4.3L= 5.7L
Step-by-step explanation:
In this question, you want to make 10 liters 20% concentration solution by mixing 5% and 40% concentration. There should be multiple answers to this question. Assuming that the total volume of 5% and 40% solution equal to 10L(no solution wasted), then you can determine the volume of solution needed. The formula should be:
Volume of a rectangular prism= W x H x L
Volume of a rectangular prism= 212 x 5 x 212
Volume of a rectangular prism= 224,720cm³
224,720cm³- 35cm³=224,865 cm³
