4+2x = x (x = student in smaller group)
4 + 2x + x = 28 (total # of students)
4+ 3x = 28
3x = 24
x = 8
8 students in the smaller group
4 + 2(8) = 20 students in the larger group
It would be 22/125.
You'd convert the fraction by placing the decimal number over a power of 10.
Answer:
$32.30 each week
Step-by-step explanation:
Deposit = 15% = $34.20
⇒ total cost of camp = (34.20 ÷ 15) x 100 = $228
Balance left after deposit = 228 - 34.20 = $193.80
If paying the remaining balance in 6 weekly installments,
⇒ weekly payment = 193.80 ÷ 6 = $32.30
Answer:
n = -1
Step-by-step explanation:
-8n + 4 (1 + 5n) = -6n - 14
-8n + 4 + 20n = -6n - 14 Distribute
12n + 4 = -6n - 14 Combine Like Terms
18n + 4 = -14 Add 6 on Both Sides
18n = -18 Subtract 4 on Both Sides
n = -1 Divide Both Sides by 18
