Fittoniya [83]
So the decrees would be 0.11 because if you add 9.55 with 0.11 you would get 9.66 then to make sure it’s right you subtract 9.66 by 0.11 and you would get 9.55. So the answer is 0.11

Which equation is equivalent to sqrt x +11=15
Bas_tet [7]

Answer:

x=16

Step-by-step explanation:

We are given that

\sqrtx+11=15

we have to solve this equation for x

in order to do that we need to isolate x first

hence

subtracting 11 from both sides we get

\sqrtx+11-11=15-11

\sqrtx=4

Now we square on both sides we get

(\sqrtx)^2=4^2

x=4 \times 4

x=16

hence x =16
