Answer:
1.79+328
Step-by-step explanation:
1.79+328
the dvr is 1.79 and it is 328 less than the tv, so if you add the 2 together you will get the cost of the tv
Hi! So, here’s what I know. Every triangle will equal to 180*. So to check if that triangles is 180 we add all angles and it should add up to 180*.
Now the question is, Why it shows that the angles of a triangle equal to 180* when added up?
Note that we see all angles lie on a straight line, therefore we know that when we add angles that lie on a straight line it will equal to 180*, they will also meet at the same point.
This is all I can help with. Hope it helped something!!! Have a great day!
3 < 3x - 3 ≤ 2x + 2
Adding -3 to each side gives
0 < 3x - 6 ≤ 2x - 1
The left inequality says
0 < 3x - 6 ⇒ 3x > 6 ⇒ x > 2
while the right inequality says
3x - 6 ≤ 2x - 1 ⇒ x ≤ 5
Then the solutions belong to the interval 2 < x ≤ 5 and contains only the integers x = 3, x = 4, and x = 5.
Part a: 7x+6
part b: 3 times the sum of a number and 8
hope this helps!
