63
5 tens equals 50
13 ones equals 13
50 +13 = 63
If you want to calculate 18/4.52, you can do this using the following steps:
18/4.52 = 18 / 4 52/100 = 18 / 452/100 = 18 * 100/452 = 1800/452 = 450/113 = 3.98
The correct result is 3.98.
In order to solve it you have to get x by itself.
1. Simplify. 1/4 + 1/2 + x is also the same as 3/4 + x. So you have 3/4 + x = -3/4.
2. Then you subtract 3/4 on both sides to get x by itself. x = -3/4 - 3/4
3. Simplify. x = -1 1/2 or -1.5 depending on whether you need the answer in a fraction or a decimal.

-1 = z/3 - 7
Emily's Work:
-1 = z/3 - 7
-1(3)=z/3(3)-7
-3 = z - 7
-3 -7 = z - 7
z = -10
Right away without having to start at the beginning, I see that she has made a mistake at the 4th-5th line of work.
Instead of adding 7 to both sides, she subtracts it and still leaves it in and doesn't fully finish the equation, as it would really be z-7 = -10
In order to solve it, follow these steps:
Rewrite the initial equation as follows:
x/3 - 7 = -1
Multiply both sides by 3
x/3(3)-7(3)=-1(3)
x - 21 = -3
Add 21 to both sides
x = 18
