18. $18 + $16 + $6 = $40
20. $300 - [3($39) + 2($62)]
= $300 - ($117 + $124)
= $300 - $241
= $59
Therefore, yes, he has enough money.
22. L = 26 W = 14
Perimeter = 26 + 26 + 14 + 14
= 80
Cost = 80ft * $13/ft
= $1040
Ordered pairs on an unit circle..
Exact values of the ordered pairs of the unit circle is represented in pictorial form above in degrees and radians.
Hope this helps.
First we have to simplify
3r + 2 < 5
subtract 2 from each side then divide by 3
r < 1
7r - 10 > 60
add ten to both sides. divide by 7.
r > 10
answer: r<1 or r>10
if you have to graph, you should have a number line going from 0 to 11. You should put an open circle on 1 and an open circle on 10. Shade to the left from the open circle on 1, and then shade from the right from the open circle on 10.
Your union should look like this:
(-♾, 1)U(10,+♾)
4(4f-8)+5= 16f-27
that’s the right answer
Answer:
Sum = 140
Step-by-step explanation:
We find all the terms, we know that every consecutive term, we add 2 until we reach 23:
Sum = 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23
Sum = 140
