a. to find the percentage, we take the total amount of white squares and divide it over the total number of squares. So it's 5/20 = 25%
b. If 80% of the cost is laying the tiles, that means the rest of the cost comes in buying the tiles (20%) this means that the ratio of that would be
80% : 20%
or simplified to
4% : 1%
Answer:
A≈<u>250</u>
Step-by-step explanation:
Yes, (1,7) is a solution.
(x,y)
y < x + 8
y ≤ 6x + 1
7<1+8 = 7<9 Yes, true.
7≤6(1)+1 = 7≤ 7 Yes, true.
Yes, (1,7) is a solution to the inequalities.
