Your grandmother has collected Christmas ornaments all of her life and has finally decided to give away 30, each year. After 10 years, she should only have 60 ornaments left, enough to decorate a
single tree. Write an equation to model the situation.

Find the y-intercept and x-intercept for the equation 5x-3y=60 what is the y-intercept

Lines b and c are parallel. what is the measure of 2? m2 = 31° m2 = 50° m2 = 120° m2 = 130°

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
