180/60 = the number of student for 1%
180/60 = 3
so 1% of the school's population is 3 students
so, 3 x 100 = 300 students
and to check:
300 x .60 = 180
so, the total population of the school is 300
Answer:
171
Step-by-step explanation:
multiply 380 times 0.45 so like this:
380 x 0.45 = 171
Answer:
x=3
y=-1
Step-by-step explanation:
x=4+y
by substitution it in equation 1
weget
(4+y)+y=2
4+2y=2
y=-1
x=3
So first simplify
(12^5)^6=(12^5)(12^5)(12^5)(12^5)(12^5)(12^5)
remember
if
(x^n)^m=x^nm
so
(12^5)^6=12^(5 times 6)=12^30
so 12^30=12^a
so a=30
