Lorenzo has 4 packages of granola bars. Each package has 10 bars.
He eats one bar from each package.

Which equation shows how Lorenzo can correctly find the total number of granola bars remaining?

4 × 10 – 4 = 36 granola bars

4 × 10 × 1 = 40 granola bars

4 × 10 + 4 = 44 granola bars

4 + 10 – 4 = 10 granola bars

A. 4 x 10 - 4 = 36

Step-by-step explanation:

Ten bars are in a package and there are 4 packages

1 bar is eaten from the 4 packages

40 - (1 x 4) =

40 - 4 =

36

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
