Answer:
D) division
Step-by-step explanation:
we know that a ratio is a quantitative relation between two numbers
so let's say
the ratio of boys to girls is 3:4
we know that for every 3 boys there are 4 girls
therefore it is a division operation
Answer:
Both of the equations are right because if you take s=4p, then reverse it, p=1/4 of s because 4 of p is equal to s so s/4 = p
(6x-18)(x+4)/(3x-9)=6(x-3)(x+4)/3(x-3)=2(x+4)=2x+8
Answer:
a(4) = 15/4
Step-by-step explanation:
Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.
Thus, the geometric sequence formula specific to this case is
a(n) = 30(1/:2)^(n-1).
What is the fourth term? Let n = 4,
a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or a(4) = 30(1/8) = 30/8, or, in reduced form,
a(4) = 15/4.
Answer:
x < 3
Step-by-step explanation:
2(4+2x)>5x+5
Distribute
8 +4x > 5x+5
Subtract 4x from each side
8 +4x-4x > 5x-4x+5
8 > x+5
Subtract 5 from each side
8-5 > x+5-5
3 > x
X must be less than 3
