Use proportion, so multiply 100 by 75, then divide it by 30 and that's your answer.....250
I am honestly not sure about this answer... try Khan Academy. Or, try breaking it down into steps.
I hope this helped... sorry about that. I will try this concept soon. :)
Sophia is 12. Four times that is 48. If her mother is 5 years less than this, she is 43.
(12 x 4) - 5 = 43
The first one shouldn't have a remainder
The answers are 507 and 125.75 or 125.7
Step-by-step explanation:
Solution:
Given:-
(X+y,y+3)=(6,2y)
Equating corresponding elements,we get,
X+y=6------(1)
y+3=2y-----(2)
solving equation (2),
y-2y=-3
-y=-3
y=3.
Now, substituting y=3 in equation (1)
X+3=6
X=6-3
X=3
Therefore,. (X,Y) = (3,3)
