Answer:
x = 28
Step-by-step explanation:
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
Then x/(x +10) = 42/(42 +15)
x(57) = 42(x + 10)
57x = 42x + 420
15x = 420
x = 28
Answer:
456 students
Step-by-step explanation:
38% = 0.38
1200 x 0.38 = 456
(1/2)x + x + (1/5)y + y = 32
(3/2)x + (6/5)y = 32
Probably d as the the temperature outside is unpredictable and the we know the time is always going up
A)24 boards/1 * 47.5 inch/boards * 1 ft/12in = 95 ft.
according to dimensional analysis the answer is 95 ft.
b) 95/8 is approximately 12 so 12 boards are needed.
