Answer:
C - 119=180 (sum if angel in st. Line)
C =61
Step-by-step explanation:
Now, angel c =angle D (VOA)
Hence, c= 61 & d=61
Let x = age of jack
Let y = age of Lacy
x=3y (Jack age is 3 times that of Lacy)
(x+y)-8 = 25
Substituting value of x:
(3y+y) -8 = 25
4y - 8 = 25
4y = 33
y = 33/4 = 8.25 or 8 years 3 months (age of Lacy)
x = 3(8.25) = 24.75 or 24 years 9 months (age of Jack)
Checking:
Substituting in equation ( x + y ) -8 = 25
24.75 + 8.25 - 8 = 25
25 = 25
Answer:
im not ok really and i don't know
Step-by-step explanation:
So u times it first so -15p-15-63+9p
so it would short it down because of cobine like terms -6p-78
15 times .25 or 1/4
(1lbs=4 kids, 15 divided by 4= 3.75)
6.25 divided by .5 is over 12
so 12 adults
