5. a pizzeria charges $8 for a large cheese pizza,
plus $2 for each topping. the total cost for a large
pizza is given by the equation c-2t + 8, where t is
the number of toppings. graph the equation for
1 between 0 and 5 toppings, and explain the meaning
of the slope and y-intercept.

Abus travels 36 miles in 45 minutes. enter the number of miles the bus travels in 60 minutes at this rate.

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
