Answer:
x=-3
Step-by-step explanation:
Given: 2(x+1)=3x+5
Distributive Property: 2x+2=3x+5
Subtract 2x on both sides: 2=x+5
Subtract both sides by 5: x=-3
Therefore, x=-3

Answer:
D. Triangle is correct
Step-by-step explanation:
We are given that,
A polygon is rotated to form the blue block patterns,
As, from the figure, we see that,
The polygon being rotated has three sides.
So, the polygon is a triangle.
Thus, a triangle is rotated to form the blue block pattern.
Hence, option D is correct.
Answer:
The answer is D) Triangle
Answer:
$2.50
Step-by-step explanation:
This problem is asking for the unit rate. To solve this problem, you would do $12.50 divided by 5 to get $2.50.
$12.50 divided by 5 = $2.50
Answer:
$2.50
Step-by-step explanation:
To get this answer you need to divide 12.50 divided 5. When you do this you will get $2.50.
Answer:
x = {120°, 240°}
Step-by-step explanation:
cos x = -1/2 for 0 ≤ x ≤ 360°
That cosine of x = -1/2 tells us two things immediately: 1) the hypotenuse has length 2 and the side adjacent to the angle x is -1. To have a negative adjacent side, angle x must be in either Quadrant II or Quadrant III.
If in Quadrant II, the terminal side of angle x is 30° past 90°, which means that x = 120°. If in Quadrant III, the terminal side of x is 30° short of 270°, which means that x = 240°
Then x = {120°, 240°}
