To find a, you need to isolate/get the variable "a" by itself in the equation:

$\frac{1}{2} (a-7)=33$ Multiply the inverse of 1/2, which is 2, to get rid of the fraction

$(2)\frac{1}{2}(a-7)=(2)33$

a - 7 = 66 Add 7 on both sides to get "a" by itself

a - 7 + 7 = 66 + 7

a = 73

Shayna enlarged a square photo by adding 10 inches to each side so it could be seen on a large poster. The area of the enlarged

Dvinal [7]

Answer:

The correct answer is:

6 inches by 6 inches

Step-by-step explanation:

Given that

Area of Enlarged photo = 256 square inches

Let x be the side of original photo

then the equation for area of new enlarged photo will be:

$(x+10)^2 = 256$

We have to solve the given equation to find the side length of original photo

Taking square root on both sides

$\sqrt{(x+10)^2} = \sqrt{256}\\x+10 = 16$

Subtracting 10 from both sides

$x+10-10 = 16-10\\x = 6$

So the side length of original photo is 6 inches. The dimensions will be 6 inches by 6 inches.

Hence,

The correct answer is:

6 inches by 6 inches
