Tell whether the given number is a solution of each question. ( Must show work for credit) 1. 9 = 2a + 3; 3

2. 5n - (-30) = 5; 7

3. 4.4r - 2.8 = 1.6; 1

Answer/Step-by-step explanation:

1. ; 3

Let's solve for a.

(subtraction property of equality)

(division property of equality)

Therefore, 3 is a solution to 9 = 2a + 3

2. ; 7

(- × - = +)

(Subtraction property of equality)

(division property of equality)

Therefore, 7 is not a solution of

3. ; 1

Therefore, 1 is a solution of .

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

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.
