Our equation is:
(x/-4)+11=5; we need to get x by itself in order to solve. Let's subtract 11 from both sides. (x/-4)=-6; let's now multiply both sides by -4. x=24; let's check to see if x is 24 by plugging it in.
24/-4=-6+11=5
So, x=24.
To find mean/average it's fairly simple!! :)
The first thing you should do is add up the first numbers -
* 20 + 15 + 16 = 51 :)
* 16 + 19 + 17 = 52
Now divide each of the scores by the amount of numbers there is -
* 20 (1) 15 (2) 16 (3)
* 16 (1) 19 (2) 17 (3)
51 ÷ 3 = 17 (Rolanda's Average Score)
- Which # is bigger?
52 ÷ 3 = 17.3 (Jetta's Average Score)
<span>The total number (n) = 28. This includes the number of cats (c) and the number of dogs (d), which is three times the number of cats. Therefore n = c + d and 28 = c + 3c. 28 = 4c. C = 28/4. C = 7. Kim trained 7 cats.</span>
Answer:
x = 7.99 cm
Step-by-step explanation:
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(AC)cosC
Substitute the measures of the sides and the angle in this formula,
x² = 6² + 10² - 2(6)(10)cos(53°)
x² = 36 + 100 - 72.217
x² = 63.782
x = √(63.782)
x = 7.99 cm
