Let the number be x.
2x-3=55
2x=55-3
2x=52
x=52/2
x=26
Answer:
12x + 40y
Step-by-step explanation:
4(3x+10y)
multiply the outer number (4) with all the terms inside the parentheses
4 X 3x + 4 X 10y
12x + 40y
Answer:
Step-by-step explanation:
The first equation is the weights of the rabbit and the ferret together which is
r + f = 7.
The second equation puts the weight of the ferret in terms of the rabbit. If the ferret's weight is 2 pounds more than the rabbit, then
f = r + 2 (the word "is" means equals). Since we know what f is equal to, we will sub it into the first equation and solve for r:
r + (r + 2) = 7 and
2r + 2 = 7 and
2r = 5 so
r = 2.5 pounds.
A rabbit weights 2.5 pounds and the ferret weights 7 - 2.5 which is 4.5 pounds.
Answer:
A
5(15x-4)^3
Explanation:
I assume you mean g(f(h(x))) so in that case here is how you do it:
So the first one is g(x) which is:
5x^3
Now g(f(x)) you just plug in f(x) for the x in the g equation. It would look like this:
5(5x-4)^3
Now the h(x) you would do the same, plug it in for all the values of x in g(x). So it would look like this:
5(5(3x)-4)^3
Since you simplify, you get 5(15x-4)^3
This final equation is g(f(h(x))) which is what you were looking for, which is A
Answer:
The curve surface area(CSA) of a cylinder is 2πrh.
Since diameter=1.5 in.
radius=diameter/2
=1.5/2 in.
=0.75 in.
And, the height of the bottle is 5 in.
Now,
CSA=2πrh
=2π*0.75*5 in^2
=15π/2 or 23.56 in^2
The size of the label needed to cover the entire bottle is 15π/2 or 23.56 in^2.
