Hello there!
The answer is 13 trust me. the answer should be 29 for no reason. but answer 13 and you'll get it right.
I don't know how to take a screen shot and post. but the easy way is to count . so 50 years old = 15. 60 years old = 8. 70 years old = 4. 80 years old = 2. add them.
Answer:
x= -1.
Step-by-step explanation:
4-2(x+7) = 3(x+5)
4 - 2x-14 = 3x +15
10-2x=3x+15
10=5x+15
-5 = 5x
-1 = x
Hope this helps. Let me know if you need any help.
The given equation is a wave function. When plotted, the graph is shown in the attached picture. However, the unit is in degrees instead of radians. A unit of π is equivalent to 180°. This plot could determine one variable if the other is given.
Answer:
2y=52
Step-by-step explanation:
1st equation *(-3) and 2nd *(2)
-6x-10y=34
6x+12y=18
eliminate -6x and 6x
add both equations
2y=52
Answer:
If the slopes of the lines are both zero, the lines are horizontal and are parallel by definition. Since the slopes of vertical lines are undefined and not considered equal, vertical lines will not be considered.
I hope this helps you :)
