5 1/6 + -3 5/6
=
31/6 + -23/6
=
8/6
=
4/3
Answer: it is th
Step-by-step explanation:
A) angle A = 180-135= 45 degrees
Angles A and 135 are supplementary angles
b) angle B= 135 degrees
because the two 135 angles are vertical angles ( opposite angles made by two intersecting line)
c) angle C = 45 degrees
because angles C and angles A are corresponding angles since line (1) and line (2) are parallel

3 pencils times 21p= 63p
2pens times 37p=74p
3sharpeners times 86p=258p
63p+74p+258p=£3.95
£8-3.95=£4.05
£4.05-£1.60= £2.45
£2.45-£1.60=85p

I am assuming it wants it “y=mx+b” form, you would start with the formula “y-y1=m(x-x1)”
You get: y-17=-4/3(x-(-9))
Simplify: y-17=-4/3(x+9)
Distribute: y-17=-4x/3-(36/3)
Simplify Fraction: y-17=-4x/3-12
Add “17”: y=-4x/3 +5
