Ok so you know that 7+7 is 14 well add just one more and your done! Which will be 15.
I might not be right here but i think its C, now before you just leave to circle the answer, find out why: Multiply 54 and 8 to find out how many TOTAL square tiles you need. The answer would be 432. Then since it says 8 groups of 4 blue tiles, this mean 8*4, which is 32. 32 of the TOTAL square tiles would be blue. subtract 432-32 to get 400 because the question is asking for the WHITE tiles. this is why you subtract the total tiles from the blue tiles to get the white tiles.
Answer:x=5/3 y=14/3
Step-by-step explanation:
y=4x-2...........(1)
y=x+3..............(11)
Subtract (11) from (1)
0=3x-5
Collect like terms
3x=5
Divide both sides by 3
3x/3=5/3
x=5/3
Substitute x=5/3 in y=x+3
y=5/3 + 3
y=(5+9)/3
y=14/3
Therefore x=5/3 y=14/3
Answer:
If 10 is the average then 10 each side would be 20
so that 15 fits into 20 at 3/4
1- 3/4 = 1/4
So the answer is 1/4

Answer:
13. She will have saved 1020 in 12 months and 467.5 in 11. 14. In 1 month she'll have saved 42.5 in 1 month and 212.5 in 5 months. 15. in 3 months she'll save 125 and 190 in 4 months. 16. The rate of change is 42.5. 17. It depends on your thoughts on what was more challenging, and knowing the rate of change can tell you half of certain amounts of money earned or what the difference between her earning months are. 18. I have no idea the y intercept someone else might be able to help you with that though. 19. I don't know that either someone else might help better.
