Answer:
-9/2
Step-by-step explanation:
-7-3a=17
-1-17=3a
-18=3a
a=-18/3
a=-6
The value of fac{3}{4} a = (3/4)(-6)
= -18/4
= -9/2
Answer:
Surface Area = 283
Step-by-step explanation:
Radius = 3
Height = 12
Formula for suface area is SA= 2πrh+2πr^2
let "r" be for radius
let "h" be for height
SA=2*π*3*12+2*π*3^2
SA=282.74
round to the nearest ones spot and that will make the surface area = 283
Answer:
At least 39200 students.
Step-by-step explanation:
Given that there are 196 countries in the world, and each country would have at least 200 students in a university.
For each country to have at least 200 students in the university, then;
Number of students enrolled in the university = number of required students x number of countries
= 200 x 196
= 39200
At least, 39200 students must be enrolled in the university. Provided that the admission procedures are conditioned for the purpose.
Through trial and error:
(7x-6)(3x-2)
Usually it works best to test out a number of possibilities :)
