Answer:
A constant of $20 can be multiplied by the number of months to find the amount in the account.
Step-by-step explanation:
4×20=80
7×20=140
Answer:
40/3, 172/3, respectively
Step-by-step explanation:
x + 9 = 2y
2x = 2y + 2
x + 9 = 2(2x - 2)
4x - 4 = x + 9
3x - 13 = 0
x = 13/3
y = 40/6
RT = 13/3 + 9 = 40/3
QS = 160/3 + 4 = 172/3
Answer:
Step-by-step explanation:
Cost price = $n
Mark up price = selling price- cost price
= (20% × $n)
Selling price = $n + (20% × $n)
Sales tax = 5% × ($n + (20% × $n))
Total cost = selling price + sales tax
Total cost = $n + (20% × $n) + 5% × $n + (20% × $n)
= 1.2 × $n + 0.06 × $n
= 1.26 × $n.
You can not solve for a as all of the numbers are unknown
Answer:Do you have a pic of the map? It would make it easier to solve if I could see the map. Its basic area. A=base times height. If the park is 50 m long and is a square, you would do 50 times 50=2500
