Answer:
<u>Marge's</u> present age = 14 ; <u>Dan's</u> present age = 29
Step-by-step explanation:
Let Marge's present age be = M
Dan's present age [D] : 14 years elder than Marge = M + 14
Marge Age = M - 8
Dan's Age = D - 8 = (M + 14) - 8 = M + 6
{Given} : Dan's age = 3 times Marge's age
M + 6 = 3 (M - 8)
M + 6 = 3M - 24
6 + 24 = 3M - M
30 = 2M
M = 30/2
M = 15 [Marge's present age]
Dan's present age [D] = M + 14 = 29
The illustrated property of the statement is the addition property of equality. I hope I helped!
The chances of rolling an 8 on a 8 sided dice is 2% so 2/10 or 25/100
First, find the number of people who need chairs.
18 + 9 + 15 + 12 = 54
Subtract the people who cant come
54 - 6 = 48
Divide by amount of chairs per row
48/6 = 8
C. 8 rows of chairs are needed.
Answer:
211
Step-by-step explanation:
360 - 149 = x
x = 211°
since its a circle the angle is 360°. so you gotta subtract the 149 to get the other part of it. full circle angle is 360°. to check your answer add 211 + 149 to get 360.
