First bring 3x to the other side, which will give you -2y= -16-3y. Then divide everything by -2, which will give you y=8+3/2x
They want you to write the number in index form.
The number is 5N^2, where N = 3 x 5^2 x x^3
So:
5N^2 = 5 x (3 x 5^2 x x^3)^2
= 5 x (3^2 x 5^4 x x^6)
= 3^2 x 5^5 x x^6
or a bit neater looking: 3² ₓ 5⁵ ₓ x⁶
Answer:

Answer:
k = 2
Z = 3.5
Step-by-step explanation:
Z = kX/Y
Where,
X = 3
Y = 1
Z = 6
Find k
Z = kX/Y
6 = k3/1
Cross product
6 * 1 = 3k
6 = 3k
k = 6/3
k = 2
what is the value of Z when X equals seven and why equals four
X = 7
Y = 4
Z = ?
k = 2
Z = kX/Y
= (2*7)/4
= 14/4
= 3.5
Z = 3.5
