Answer:
- ![\sqrt{13.7} = 3.70135110](https://tex.z-dn.net/?f=%5Csqrt%7B13.7%7D%20%20%3D%203.70135110)
- ![3.05^{2} = 9.3025](https://tex.z-dn.net/?f=3.05%5E%7B2%7D%20%3D%209.3025)
- 2.6
- Add 9.3025 and 2.6 = 11.9025
- Divide 3.70135110 by 11.9025
= 0.31097257
Answer: 3000 stamps
Step-by-step explanation:
Given
Chris and Josh have 1800 stamps
Josh and Jessica have 2200 stamps
Jessica and Chris have 2000 stamps
Suppose Chris, Josh, and Jessica have
stamps
![\therefore x+y=1800\quad \ldots(i)\\\Rightarrow y+z=2200\quad \ldots(ii)\\\Rightarrow z+x=2000\quad \ldots(iii)\\\text{Add (i), (ii), and (iii)}\\\Rightarrow 2(x+y+z)=1800+2200+2000\\\Rightarrow x+y+z=3000](https://tex.z-dn.net/?f=%5Ctherefore%20x%2By%3D1800%5Cquad%20%5Cldots%28i%29%5C%5C%5CRightarrow%20y%2Bz%3D2200%5Cquad%20%5Cldots%28ii%29%5C%5C%5CRightarrow%20z%2Bx%3D2000%5Cquad%20%5Cldots%28iii%29%5C%5C%5Ctext%7BAdd%20%28i%29%2C%20%28ii%29%2C%20and%20%28iii%29%7D%5C%5C%5CRightarrow%202%28x%2By%2Bz%29%3D1800%2B2200%2B2000%5C%5C%5CRightarrow%20x%2By%2Bz%3D3000)
Thus, all three have 3000 stamps
The answer I got was C = The car used 70 gallons of gas to go 3 miles.

Answer:
The answer is below
Step-by-step explanation:
Since 1000ml Of Dextrose 25% is needed to be produced from Dextrose 70%. Let us assume that x ml of Dextrose 70% is mixed with a Dextrose 5% to get 1000 ml of Dextrose 25%. Hence:
The amount of Dextrose 5% = 1000 ml - x ml = 1000 - x
25% of 1000 ml = 70% of x + 5% of (1000 - x)
25000 = 70x + 5000 - 5x
Simplifying gives:
65x = 25000 - 5000
65x = 20000
x = 308 ml
Therefore 308 ml of Dextrose 70% was mixed with 692 ml of Dextrose 5% to produce 1000 ml of Dextrose 25%.
