Mrs. Smythe = x
Daughter = y
x = 2y
(x - 10) + (y - 10) = 46
x - 10 + y - 10 = 46
x + y - 20 = 46
x + y = 66
Put 2y in for x
2y + y = 66
3y = 66
y = 66/3
y = 22
The daughter is 22
The mother = 44
If he increases the number by 10%, he will have 110% of the number.
Then he reduces it by 10% of the new number, which s 11%.
110% - 11% = 99%
The answer is 99%.
Hope this helps!
Answer:
4 ml
Step-by-step explanation:
m = D/ v where m is mass and D is density and V is volume
.875 = 3.5 / V
Multiply each side by V
.875 V = 3.5
Divide each side by .875
V = 3.5/.875
V =4
