First, convert 3 1/2 into an improper fraction, which is 7/2. Now, you have to make sure both sides have a common denominator. This will be 6. So now the equation is 21/6 - 4/6. Subtract the numerators, which is 17. Keep the denominator, however. Now, simplify. You new answer will be 2 5/6.
Answer:
3) B) 90°
4) A) 75°
Step-by-step explanation:
3) interior angles of a triangle =180°
So
40+50+?=180
? =180- 90
? =90
4) same rule
40+65+?=180
? =180 - 105
? = 75

I would say ten or five but it is not specific enough to have a correct answer.
Answer:
B. 126 degrees
Step-by-step explanation:
lets say the angle is x
the equation we have here is the 8th graders divided by the total number of students is equal to x divided by 360 degrees since a circle has a 360 degree angle.
The equation is:
350/1000=x/360
in number form.
350/1000= 0.35 = 35%
so now we know x/360=35%
126/360=35%
so the answer would be 126 degrees.
