if ya add 10 u get zero, so add 13 n u get 3......which grade are u in btw :P
You add 10 to -7 to get 3.
- 10 + x = 3 Add 10 to both sides: 0 + x = 3 + 10 or x = 13
4
Oh, dude, you just need to add 3 to 7 to make one whole. Like, it's simple math, right? So, 7 + 3 equals 10, which is one whole. Easy peasy lemon squeezy!
To make 243 divisible by 10, we need to find the nearest multiple of 10. The nearest multiple of 10 less than 243 is 240. To make 243 divisible by 10, we need to add 240 + 3, which equals 243. Therefore, we need to add 3 to 243 to make it divisible by 10.
You need to add 18 to negative 8 to get 10.
you need to add 10
your expression is this... x + -10 = 2 x = 12 You need a 12 to add to -10 to get 2
-10
-10 + 20 = 10 because you need 10 to get 0 and 10 more to get +10
if you mean 9/10 + 3/5 then multiply 3/5's numerator and denominator to get 6/10, which you can add to 9/10 to get 15/10, or 3/2. 1 1/2 if you need mixed numbers.
10 - (-9) = 19
