Answer:
280
Step-by-step explanation:
2/3 x 42=28
28 x 10 = 280
1)You add 9 to both side; so you subtract 9 from nine which leaves you 0
2)you subtract 9 from the other side, because you have to do the same things to both sides. so you get 7-9. Which equals -2.
3) you're equation will look like : p<-2
Answer:
225 inches²
Step-by-step explanation:
Let the length be l and width be w
Condition 1
2l+2w=68 (Perimeter=68)--------(i)
Condition 2
l=3w-2 ---------(ii)
Putting equation (ii) in (i)
2(3w-2)+2w=68
6w-4+2w=68
8w-4=68
8w=68+4
8w=72
dividing both sides by 8
w=9 inches
now putting w=9 in (ii)
l=3(9)-2
l=27-2
l=25 inches
Now
Area of rectangle = l × w
=9 × 25
=225 inches²
Answer: Length = 25 in., width = 9 in.

took the quiz in K12
Answer:
It would take 6 minutes to purify enough water.
Step-by-step explanation:
Water purifier will purify 1 liter of water in 1 minute.
Terrell needs enough water for 4 canteens that each hold 750 ml.
Water for 4 canteens = 750 ml × 4 = 3000 ml = 3 liters
water for 2 canteens = 1.5 L × 2 = 3 liters
Water for total canteens = 3 + 3 = 6 liters.
Now it is given that water purifier will purify 1 liter of water in 1 minutes so 6 liters of water will purify in 6 minutes.
Answer: < n <
Step-by-step explanation:
| 3n - 2 | - 2 < 1
+2 +2
| 3n - 2 | < 3
3n - 2 < 3 and 3n - 2 > -3
+2 +2 +2 +2
3n < 5 and 3n > -1
n < and n >
< n <
