Answer:
If Father is four times older than Mary, that would be 4 times 10-- which equals 40. Five years ago, Mary must have been 5 years old. So, multiply 7 and 5 and you'll get 35! Father would have been 35 years old.
I hope this helps!

Answer:
100°
Step-by-step explanation:
360 degrees around a point.
140 + 120 = 260
360 - 260 = 100
Step 1: multiply the numbers in front of the parentheses with each term inside the parentheses
15p - 9 = 5p - 5
Step 2: get like terms on the same side
10p = 4
Step 3: divide both sides by 10
p = 4/10
Step 4: simplify
p = 2/5
Answer:
Basically G is centeroid (intersection point all three medians) so it divides BD in the ratio of 2:1
if bd is x then 2x/3 = BG i.e 38
so GD is x/3 i.e 19
