maddy had twice as many stamps as simon. After maddy sold 60 stamps, simon had twice as many stamps as maddy. how many more stamps did maddy have than simon in the beginning

Step-by-step explanation:

Here are your equations:

M=2S

S=2(M-60) --> solve for M and S --> M=80, S=40

In the beginning, Maddy had 40 (80-40) more stamps than Simon.

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
