Answer:
a) x = 34
b) yes, it checks out
Step-by-step explanation:
2x - 5 = 3(4 + 1/2x)
multiply both sides by 2 to eliminate fraction
2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x
x - 10 = 24
x = 34
<u>check</u>
2(34) - 5 = 3(4 + 34/2)
68 - 5 = 3(4 + 17)
63 = 3(21)
63 = 63

Answer:
Total number of student next year = 54,648
Step-by-step explanation:
Given:
Total number of student = 54,000
Growth rate = 1.2% each year
Find:
Total number of student next year
Computation:
Total number of student next year = Total number of student(1+Growth rate)
Total number of student next year = 54,000(1+1.2%)
Total number of student next year = 54,648
Answer:
Volume: 120
SA: 400
Step-by-step explanation:
Volume = Bh
Volume = (1/2 x b x h) h
Volume = (1/2 x 6 x 4) 10
Volume = 120
SA = 2B + Ph
SA = 2(1/2 x b x h) + (s + s + s)h
SA = 2(1/2 x 6 x 4) + (5 + 5 +6) 10
SA = (24 + 16) 10
SA = 40 x 10
SA = 400
