Answer:
one solution
x = 12
Step-by-step explanation:
3 (x-1) = 2x + 9
3x - 3 = 2x + 9
subtract 2x from each side of the equation:
x - 3 = 9
add 3 to each side:
x = 12
Answer:
Step-by-step explanation:
c varies jointly with d and the square of g
where, k is constant of proportionality.
Put the given value c = 30 when d = 15 and g = 2 and find out k
If c = 6 and g = 8 then d = ?
Hence, The value of d is
Remember
(x^m)(x^n)=x^(m+n)
and
if a^m=a^n, where a=a then n=m
(x^4)(x^n)=x^5
(x^4)(x^n)=x^(4+n)
x^(4+n)=x^5
therefor
4+n=5
minus 4
n=1
The estimate is twelve because five goes into sixty roughly twelve times.
