1 ) 9 x + 18 > 9 x - 27
9 x - 9 x > - 27 - 18
0 * x > - 45
Always true
2 ) 6 x - 13 < 9 x - 12
6 x - 6 x < - 12 + 13
0 * x < 1
Always true
3 ) - 6 ( 2 x - 10 ) + 12 x ≤ 180
- 12 x + 60 + 12 x ≤ 180
0 * x ≤ 180 - 60
0 * x ≤ 120
Always true.
Answer:
34 members
Step-by-step explanation:
The math club at Emily's middle school has the number of members = 40
On Saturday only 85% of the members were attend the meeting.
Number of members who attend the Saturday meeting
= 85% of 40
= 0.85 × 40
= 34 members
34 members attend the Saturday meetings.
Answer:
x = 8.12
Step-by-step explanation:
36+x^2 = y^2
121 + x^2 = z^2
z^2 + y^2 = 289
(121+x^2)+(36+x^2) = 289
157 + 2x^2 = 289
2x^2 = 132
x^2 = 66
x = 8.12
HOPE THIS HELPS!!!
7 girls on a bus, each has two legs. 7 * 2 = 14.
Each girl has 7 backpacks. So 7 * 7 = 49.
49 * 7 = 343 cats in total
343 * 4 = 1,372 cat legs.
343 * 7 = 2401 small cats
2401 * 4 = 9,604 cat legs
14 + 1,372 + 2,401, + 9,604 = 10,990 legs in total
