The right angle,(2x+11)°,and 53° are supplementary therefore

90°+2x+11+53=180°

2x+154°=180°

2x=180°-154°

2x=26°

What is the value of the unknown number in the verbal description? 5 times the sum of 12 and a number is 80.
mixer [17]
"5 times a sum of 12 and a number is 80" translates to the next equasion:

5 x (12+a) = 80

Now we just have to solve it to find the value of a.
5 \times (12 + a) = 80 \\ 60 \times 5a = 80 \\ 5a = 80 - 60 \\ 5a = 20 \\ a = 20 \div 5 \\ a = 4
The unknown number is 4.
D is the right answer.

bazaltina [42]

Answer:she had 11 video games on Monday.

Step-by-step explanation:

Let x represent the number of video games that Susie had initially.

On Tuesday, Susie buys three new video games from the store. This means that the total number of video games that Susie had would be x + 3

On Wednesday, she sells half of her video games in order to make extra money. This means that the number of video games that she sold is

(x + 3)/2. The number of video games left would be

x - (x + 3)/2

If she has 4 video games left after selling, it means that

x - (x + 3)/2 = 4

2x - (x + 3) = 8

2x - x - 3 = 8

x - 3 = 8

x = 8 + 3 = 11
