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

Rolling a number less than 4 on a number cube labeled 1 through 6

olga_2 [115]

Rolling a number less than 4 means that rolling a 1, 2, or 3 will satisfy the requirement. Since 3 of 6 possible outcomes will satisfy the requirement then the likelihood that it will be rolled is 3/6 times. 3/6 reduces to 1/2 or 50% chance.
