Answer:
8√3
Step-by-step explanation:
3√12 = 3√4 x 3 = 5√3
√27 = 3√3
5√3 + 3√3 = 8√3
1.05/0.6 = $1.75 per pound
1.75 * 3 = $5.25 for 3 pounds of apple
Answer:
Yusuf = 37.5
Ajay = 13.5
Step-by-step explanation:
Lets say.. Yusuf = y and ajay = a
y = 24+a (since yusuf is 24 years older than ajay)
5 years before, the sum of their ages was 41 so subtract 5 from y and a and add the two.
(y-5)+(a-5)=41
We already have defined y in terms of a (y =24+a) so we substitute that in for y.
(24+a-5)+(a-5)= 41
24-5 = 19
19+a+a-5=41
a+a = 2a
2a+19-5 = 41
19-5 = 14
2a+14 = 41
subtract 14 from both sides
2a=27
a=13.5
substitute that in y=24+a
y=24+13.5
y=37.5
lets check these answers.
(37.5-5)+(13.5-5)= 41
37.5-5 = 32.5 and 13.5-5= 8.5
32.5+8.5=41??
Correct!
3. Zack missed the way: 0 boxes, 53 pots.
4. No. 53 is not evenly divisible by 10.
5. The number of ways Zack can plant his flowers is 1 more than the number of 10s in the number of flowers he has. If Zack has 10a +b flowers (0 ≤ b ≤ 9), then he can plant them (a+1) ways.
