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%.

<u>Answer</u>
A) 7.3 in.
Explanation
The area of a triangle = 1/2 ×base length × height
In the question given, base length = height = x
Area = 27 in²
1/2 × x × x =27
1/2×x²=27
x² = 54
x = √54
= 7.3485 in²
Y because if you add them you will get 10x =-10
The y will be eliminated because you have positive 3 -4
Answer:
2y=52
Step-by-step explanation:
1st equation *(-3) and 2nd *(2)
-6x-10y=34
6x+12y=18
eliminate -6x and 6x
add both equations
2y=52
