To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
There are no parentheses or exponents in this expression, so to the next step (Multiplication/Division)
Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right.
In this case that would be division first then multiplication.
NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression
50÷5+3×4÷2-1
50 ÷ 5 = 10
10 + 3 × 4 ÷ 2 - 1
3 × 4 = 12
10 + 12 ÷ 2 - 1
12 ÷ 2 = 6
10 + 6 - 1
Addition/Subtraction
10 + 6 - 1
10 + 6 = 16
16 - 1
15

Answer:
27. Alternate exterior angles are congruent.
28. Same-side interior angles are supplementary.
Step-by-step explanation:
27. The two angles whose measures are set equal by the equation are on opposite sides of the transversal, so are "opposite." They are "outside" the space between the parallel lines, so are "exterior." These descriptors identify the angles as "opposite exterior" angles. The theorem/postulate that lets you set their measures equal is ... [the one written above].
28. The two angles whose measures are added in the equation are on the same side of the transversal, so are "same-side" angles. They are "inside" the space between the parallel lines, so are "interior." These descriptors identify the angles as "same-side interior" angles. The theorem/postulate that says their measures sum to 180° is ... [the one written above].
Answer:
Correct answer is <em>"reflection, then rotation".</em>
Step-by-step explanation:
The figure shows the following two operations:
1) Reflection through central horizontal line. ()
2) Rotation with center at the upper left corner of the reflected figure. ()
Therefore, correct answer is <em>"reflection, then rotation".</em>
