Answer:
k = d + 3
k - 2 = 4( d - 2 )
Step-by-step explanation:
Let k be Kevin's age and Let d be Daniel's age.
Given : Kevin is 3 years older than Daniel.
i.e. Age of Kelvin = Age of Daniel+ 3
i.e. In terms of variables , k= d+3 (1)
Two years ago,
Age of Kelvin = k-2
Age of Daniel = d-2
Since Two years ago ,Kevin was 4 times as old as Daniel.
i.e. In terms of variables : k -2 = 4 x (d-2)
k-2=4(d-2) (2)
From (1) and (2) the system of equations represents this situation are
k = d + 3
k - 2 = 4 ( d - 2)
I think the answer would be 112. I did this by solving the square first which would be 10×10 and then moving on to the triangle which would be 4×6÷2 hope this helps
The variable is h and t
the terms is 7h+3-t
the coefficients is 7
