Answer:
True: If you add 6 to a, this will be greater than b.
Step-by-step explanation:
If the ordered pair (a,b) satisfies the inequality y < x + 6, then the coordinates of this point satisfy the inequality. Substitute into the inequality x = a and y =b:
Check all options:
A. Subtract 6 from b:
So, if you subtract 6 from b it will be less than a but never equal to a, so this option is false.
B.
So, a is greater than b - 6, not b. This option is false.
C. If you add 6 to a, then
This option is true.
D. a+6 is greater than b, so it cannot be less than b. This option is false.
Let S(n) the statement, 2 is a factor of .
For n=1, 1^2 + 7(1) = 1 + 7 = 8, 1 is a factor of 8, then S(1) is true.
For n=2, we have 2^2 +7(2) = 4 +14 = 18, of course, 2 is a factor of 18, then S(2) is true.
For n=3, we have 3^2 +7(3) = 9 +21 = 30, of course, 2 is a factor of 30, then S(3) is true.
Answer:
268
Step-by-step explanation:
2(2×6+2×2+2×6) + 2(4×5+4×10+10×5) - 2(2×2)
= 56+220-8
= 268 cm²
This one is not too bad. They're telling us the total pie is $3,500 and the share of bills 40%. So we want
40% of 3500 = .40 (3500) = $1400
Third choice
