Answer:
4 blue dogs
Step-by-step explanation:
Since there are 6 black dogs and 5 white dogs, there is 11 black and white dogs. There is 15 dogs in total, so you subtract 11 from 15, and that is 4. So, 4 dogs are blue.
13=3+10
so it is now
3+10-7
we know that 10-7=3 so we now have
3+3=6
tada
Answer:
Mrs. Wong spend $545.76 on tiles.
Step-by-step explanation:
Mrs. Wong has 144 tiles that she is going to place on her square kitchen floor. If the tiles are $3.79 each, how much did Mrs. Wong spend on tile?

one tile cost=$3.79
and for 144 ties cost
multiplying 144 on both sides
144 tiles cost=3.79*144=$545.76
