First, let's use the distributive property on 3(a+5)
3(a + 5) = 3a + 3(5) = 3a + 15
Now, let's go back to the inequality
3(a+5) < 9
Use the distributive property
3a + 15 < 9
Subtract both sides by 15
3a < -6
Divide both sides by 3
a < -2
That's your answer.
Have an awesome day! :)
Answer:
5:4 is one ratio you can use for solving 5 being boys and 4 being girls
Step-by-step explanation:
Answer:
Neither
Step-by-step explanation:
Check if it's arithmetic:
-8, -3, 6, 11, -22
+5 +6 +5 -33
Nope
Check if geometric:
-8, -3, 6, 11, -22
*3/8 *-2 *11/6 *-2
Nope
So it's neither
To find slope, we must find the change in y values divided by the change in x values, also called the rise/run. This is modeled below:
Slope = m = (y1 - y2)/(x1-x2) = (6-(-3))/(1 - (-6)) = (6+3)/(1+6) = 9/7
We can check that this answer is correct by consulting the graph. The graph shows a positive correlation (means that the slope should be positive), and if you count the graph unit squares, you get that the graph moves up 9 squares and over 7 squares between the two points shown, letting us know we got the right answer.
Hope this helps!
Answer:
11
Step-by-step explanation:
All you have to do is plug in a. In this case, a=3.
21/a+4
21/(3)+4
21/3+4
7+4
11
