Answer:
78 boys
Step-by-step explanation:
If the raio is 2:3 that means there are 5 equal parts
56/2 28
3 x 28 = 78
The letter E would represent 9.
I hope this helped you!
Answer:
also 75°
Step-by-step explanation:
the angles across each other at a crossing point of 2 lines must be equal.
so, 2 = 3.
and the angles at the crossing point with a parallel line are simply a "mirror" or rather a copy of the angles at the crossing point with the first line.
so, 2 = 3 = 6 = 7
and 1 = 4 = 5 = 8
Horse = x = 1 head and 4 feet
Chicken =y = 1 head and 2 feet
Horse + chicken = x + y = 43 ( total heads)
Horse = 43 - y
4x + 2y = 122
4(43-y) + 2y = 122
Simplify:
172-4y + 2y = 122
Combine like terms
172-2y = 122
Subtract 172 from both sides
-2y = -50
Divide both sides by-2
Y = 25
X + y = 43
X + 25 = 43
X = 18
There are 18 horses and 25 chickens.
