Answer:
1 3, and 4 ones are correct
Step-by-step explanation:
jk
<span>a(c−b)=d
ac - ab = d
ac = d + ab
c = (</span>d + ab) / a
answer is
D. c = (d + ab) / a
The number is 18.
In order to find this, we need to take each side and turn them into mathematics statements.
Five times the sum of a number and 3.
5(x + 3)
3 times the difference of twice the number and 1
3(2x - 1)
Now that we have these, we can set them equal to each other and solve.
5(x + 3) = 3(2x - 1) ----> Distribute
5x + 15 = 6x - 3 -----> Subtract 5x from both sides
15 = x - 3 -----> Add 3 to both sides
18 = x
Answer:
10
Step-by-step explanation:
we know that,
the roof the colosseum=
(x-h)^2+(y-k)^2=r^2
where
(h,k) is the center and r is the radius
now,
(h.k)=(0,0)---(orgin)
we know that radius is half the diameter
so,
r=600/2=300
now substitute the value,
(X-0)^2+(y-0)^2=300^2
x^2+y^2=90,000
hope it helps you
