Answer:
4:!
Step-by-step explanation:
4:1 because their are 4 boys for every 1 girl
Answer:
It's option d.
Step-by-step explanation:
The line y = x + 2 has domain x < 2 (because of the clear circle.)
The lines y = x + 1 has domain x ≥ 2. ( because of the filled circle).
Adding all of these should equal to 180 from the way the angle is set up.
So the equation should be:
(3x + 2) + (2x + 5) + (2x - 9) = 180
You can remove parentheses as it doesn’t affect the equation since it is all addition.
Let’s first add the common variables together.
3x + 2x + 2x = 7x
2 + 5 + (-9) = -2
So now we should have:
7x - 2 = 180
Now add 2 to both sides.
7x = 182
Divide both sides by 7 to isolate x.
x = 26
So x is 26.
64 inches = 1 
yards
using the conversion : 1 yard = 36 inches
divide 64 by 36 to convert to yards
= 
← ( divide numerator/denominator by 4 )
= 
= 1
