Step-by-step explanation:
4x +13 +79+79+ 11x-6 = 360
15x +165 = 360
15x = 195
x =13
QRS = 11(13)-6 = 137
Answer:
D. 4/25
Step-by-step explanation:
To find probability, you multiply 4/10 by 4/10. You should get 16/100, which simplifies to 4/25.
We can l<span>abel the length (l), width (w), and height (h) of the prism and use the </span>formula<span>, SA=2lw+2lh+2hw, because it has '6' faces and to find the </span>surface area put the values in the formula:
SA=2(6)(3)+2(6)(2)+2(2)(3)
SA=36+24+12
SA=72
If you would like to know how many students were in each class, you can calculate this using the following steps:
4 buses<span> * x + 8 students = 220 students</span>
4 * x + 8 = 220
4 * x = 220 - 8
4 * x = 212 /4
x = 212 / 4
x = 53
<span>53 students were in each bus.</span>
X = 11 because if you take 11 x 2 then you get 22 then add 5 to it then you got 27 or if you do it the algebraic way subtract 5 from 27 to get 2x = 22 then divide both sides by 2 to get x = 11
