Answer:
Solution A = 2100
Solution B = 700
Step-by-step explanation:
Given that:
Let :
Millimeter of solution A = a
Millimeter of solution B = b
% alcohol, solution A =. 20% = 0.2
% alcohol solution B, = 14% = 0.14
Resulting millimeter of. Alcohol = 518
a = 3b - - - (1)
0.2a + 0.14b = 518 - - - - (2)
Put a = 3b in (2)
0.2(3b) + 0.14b = 518
0.6b + 0.14b = 518
0.74b = 518
b = 518 / 0.74
b = 700
a = 3b
a = 3(700)
a = 2100
Answer:
D is the right ans after solving eqn we get two value of x and they are 1 and 3
Answer:
76 cm
Step-by-step explanation:
To find perimeter, you find the total of the sides.
A rectangle has 4 sides, and 2 equal sides.
So, add 14+14 which is 28.
Then add 24+24 which is 48.
Now add 48 and 28.
48+28=76
<u>Final answer</u>
76 cm
