Answer:
it is the 1st one
Step-by-step explanation:
because you have to add up all three sides because you need 180 then subtract that answer from 180 and you will get your answer
Round each number to the nearest 10.
33 rounds to 30 and 89 rounds to 90, thus in your head it's easier to mentally add 30 + 90 for purposes of estimation.
Answer:
y = 2x - 3
Step-by-step explanation:
Step 1: Remember the equation
The slope intercept form is y = mx + b where m is the slope and b is the y-intercept
Step 2: Solve
We can see the y-intercept(where the line crosses the y axis) is at y = -3
We know slope is
so we can see for every 1 square it moves right it moves 2 up so the slope would be
or 2
Plug what we know into the equation
y=2x-3
Step 3: Therefore Statement
Therefore the equation of the line shown below is y = 2x - 3
64 + 5 = 69
69 + 64 = 133 cupcakes
