How do I correctly solve this?

<h3>Answer: y = 14</h3>

===================================

Explanation:

The two angles involving x add up to 180 degrees. This is because they are same side interior angles (and because the horizontal lines are parallel)

So,

(angle BCF) + (angle EFC) = 180

(5x - 66) + (2x + 50) = 180

5x - 66 + 2x + 50 = 180

7x - 16 = 180

7x - 16+16 = 180+16 ... add 16 to both sides

7x = 196

7x/7 = 196/7 .... divide both sides by 7

x = 28

This will be used to help find y

Notice how the angles BCF and ACD are vertical angles, therefore they are congruent or the same measure

angle ACD = angle BCF

9y - 52 = 5x - 66

9y - 52 = 5*28 - 66 ..... replace x with 28 (since x = 28)

9y - 52 = 140 - 66

9y - 52 = 74

9y - 52+52 = 74+52 .... add 52 to both sides

9y = 126

9y/9 = 126/9 .... divide both sides by 9

y = 14

How can the product of 7 and 0.2 be determined using this number line?
sdas [7]

Answer:

The product is <u>1.4</u>

Step-by-step explanation:

Every time you multiply 0.2 by a number you will add 0.2 to the last number.

0.2 x 1 = 0.2

0.2 x 2 = 0.4

0.2 x 3 = 0.6

0.2 x 4 = 0.8

0.2 x 5 = 1.0

0.2 x 6 = 1.2

0.2 x 7 = 1.4

Hope this helps :)
