You can add them like this:
so if 156 + 213 + 109 was the equation then you would
first put them in order from biggest to smallest
213
156
+109
-----------
then add:
¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )
then you get the answer 478!
hope that helps :)
Add positive 28 to get the sum 0
I think this is the answer :)
- Simplify both sides of the equation
=>x+5+4−5=x+54
=>x+5+4+−5=x+54
=>(x)+(5+4+−5)=x+54(Combine Like Terms)
=>x+4=x+54
=>x+4=x+54
- Subtract x from both sides
=>x+4−x=x+54−x
=>4=54
- Subtract 4 from both sides
=>4−4=54−4
=>0=50
Find the GCF of 24 and 30
24 30
1×24 1×30
2×12 2×15
3×8 3×10
4×6 5×6
The common factors are 1, 2, 3, and 6
That means we can make 6 necklaces, each necklace with 4 jade beads and 5 teak beads.
