20 trains
Step-by-step explanation:
180/9 = 20
Answer:
it should be an obtuse angle
He sleeps 144 hours a week
The value of the expression is 19
Step-by-step explanation:
- Step 1: Find the value of 9(n + 2) - 5n when n = 1/4
⇒ 9(n + 2) - 5n = 9(1/4 + 2) - 5 × 1/4
= 9(9/4) - 5/4
= 81/4 - 5/4 = 76/4 = 19
Answer:
Attaching answer for 1 below!!
2. C. -- y=2x+9
3. B. -- y=5/3x+3
Step-by-step explanation:
1. First screenshot below
2. To convert standard equations (Ax+By=C) to slope intercept (y=mx+b), what you do is preform inverse operations on A to both sides (modeled below). Then, the equation will look like this; By= -Ax+C. The last thing you need to do to cancel out B from the y is divide both sides by B, and you'll have your answer. So, I did that exact process with the equation and that's how I got C. Now, when you have no number next to the y, you don't need to divide, so it's a very simple process that way.
-2x+y=9
+2 +2
3. Same process for 2, except this time we divided by 3.
