Answer:
x = 350 gallons (amt of 60% solution that must be added)
Step-by-step explanation:
Amt of 60% solution = x gallons ; Amt of active ingredient = 0.6x gallons
Amt of 15% solution = 100 gallons ; Amt of active ingredient = 15 gallons
Amt of 50% solution = 100+x gallons ; Amt of active = 50 + 0.5x gallons
EQUATION:
Active ingredient: 0.60x + 15 = 50 + 0.50x
0.10x = 35
x = 350 gallons (amt of 60% solution that must be added)
Answer:
= x
Step-by-step explanation:
In right triangles the sum of square length of two legs is equal to square length of hypotenuse:
7^2 + 8^2 = x^2
49 + 64 = x^2 add like terms
113 = x^2 find the root for both sides
= x
3,5
1 across and 1 down pattern
find the halfway point
Y=4-3/x
y-4=-3/x
(y-4)x=-3
x(y-4)=-3
x=-3/y-4
there's you answer
Answer:
C & D
Step-by-step explanation:
Both have an odd amount of numbers, meaning there is a perfect middle.
