Answer:

$\frac{3}{4}x + \frac{1}{2}$ = One-half more than three-fourths of a number

$\frac{3}{4}-\frac{1}{2}x$ = Three-fourths minus one-half of a number

$\frac{3}{4}-(x+\frac{1}{2})$ = three-fourths minus the sum of a number and one-half

Step-by-step explanation:

Suppose x be an unknown number.

∵ 3/4th of a number = $\frac{3}{4}x$

$\frac{3}{4}x + \frac{1}{2}$ = One-half more than three-fourths of a number

Now, half of a number = $\frac{1}{2}x$

$\frac{3}{4}-\frac{1}{2}x$ = Three-fourths minus one-half of a number

Sum of a number and one-half = $x+\frac{1}{2}$

$\frac{3}{4}-(x+\frac{1}{2})$ = three-fourths minus the sum of a number and one-half

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
