103 ft^2
take 3 and 5 and multiply it by 30
3*30=90
5.5*30=165
then divide them both by 12 to convert inches to feet
90÷12=7.5
165÷12=13.75
then multiply both dividends together
7.5*13.75=103.125
then round to the nearest whole number
103
Answer:
Barney 145 3 Days 310 Miles
Mary 250 5 Days 600 Miles
A) 3 D + 310 M = 145
B) 5 D + 600 M = 250
Multiplying A) by -5/3
A) -5 D - 516.6666M = -241.66666666
B) 5D + 600M = 250
Adding A) and B)
83.3333 M = 8.3333333333
M = .10 per mile
3 D = 114
Daily Rate = 38 dollars per day
Step-by-step explanation:
Answer:
w=22
Step-by-step explanation:
5(w-2)+10=3(2w-9)+5
1) Use the Distributive Property for 5(w-2) and 3(2w-9):
5w-10+10=6w-27+5
2) Combine alike terms:
5w=6w-22
3) Add a 22 to both sides:
22+5w=6w
4)Subtract 5w from both sides:
w=22
This is a multiplication problem.
3*3/4 is equal to (3*3)/4, which is equal to 9/4. This can be further simplified to the mixed number 2 1/4
