30b+3= s
It would be thirty students times the number of buses, with an addition of 3 students equal to the total number of students when on the field trip.
I hope this helps!

Solution:
<u>Note that:</u>
- 1 pair of mittens = $3
- Kendra = $50
<u>We already know:</u>
- The closest number to 50 and is divisible by 3 is 48.
=> x pair of mittens = $3x = 48
=> $3x = 48
=> x = 48/3
=> x = 16
Kendra can buy <u>16 mittens.</u>
Answer:
x = 35° , y = 90°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
145° is an exterior angle of the triangle , then
y + 55° = 145° ( subtract 55° from both sides )
y = 90°
the sum of the 3 angles in a triangle = 180° , then
x + y + 55° = 180°
x + 90° + 55° = 180°
x + 145° = 180° ( subtract 145° from both sides )
x = 35°
