Question

what is v if √(v+3)-1=7?

Answer 1

√(v+3)-1=7
√(v+3)=8
v+3 = 64
v = 61

Answer 2

yw :)

Answer 3

what is v if 90=9√25v?

Answer 4

v=2

Answer 5

90=9√25v
10 = √25v
100 = 25v
100/25 = v
4 = v

Answer 6

when u square u should square v also isn't t?

Answer 7

if the v is under the square root, you don't square it.

Answer 8

if whole 25v is under sqrt then u right. i thought only 25 is under sqrt

Answer 9

janella, is the v inside or outside the root?

Answer 10

That's what I thought.

v = 4

Answer 11

what is n if √3n=√(4n-1)?

Answer 12

3n = 4n - 1

n = 1

Answer 13

what is n if √(2n-88)=√(n/6)?

Answer 14

2n-88=n/6
12n-528=n
11n=528
n=48

Answer 15

what is n and x if √(x/10)=√(2n-6)?

Answer 16

since there are 2 unknowns we need 2 eqns to solve them.

Answer 17

can u help me to solve that equation?

Answer 18

√(x/10)=√(2n-6)

x/10 = 2n-6

x = (2n-6)/10

n = ((x/10) - 6)/2
