Step-by-step explanation:
Express 27 in terms of cubes, 27 = 3³:

From trinomial expansion:

open first two brackets to get a quadratic equation:

expand further:

take y to be 3, then substitute:

Any two numbers, normally degrees, such as 10° and 170°, that add up to equal 180°
Answer: m∠7=130°
Step-by-step explanation:
If two parallel lines are cut by another line (transversal), each one will have four angles surrounding the intersection.
By definition, the adjacent angles of each parallel line, are supplementary, this means that they add up 180°.
Then, if m∠2=50°, then m∠3 is:
m∠3
°
By definition, the angles that are in the same relative position are know as corresponding angles and they are congruent.
Therefore:
m∠3=m∠7
m∠7=130°
Answer:
Step-by-step explanation:
a. use what's given in the question to write an equation
36x + 12y + 24e (using e as the variable for erasers)
b. 12 is the greatest common factor between the coefficients/ constant so factor it out
12 (3x + y + 2e)
12 kits
c. use the factored expression to see how many of each item
3x - 3 pencils
y - 1 crayon
2e - 2 erasers
Ask them to first estimate the quotient and then to find the actual
