Mathematics
1 answer:
KATRIN_1 [288]3 years ago
7 0

Answer:

x is equal to 0.94 and -1.94

Step-by-step explanation:

3x² + 3x + 7 = 0

9x² + 9x + 21 = 0

9x² + 9x + 2.25 = 18.75

(3x + 1.5)² = 18.75

3x + 1.5 = ±√18.75

3x = -1.5  ±√18.75

x = (-1.5  ±√18.75) / 3

x = 0.94, -1.94

Alana was working out on the treadmill. she worked out for 15 minutes. part of the time she was walking at 3.1 miles per hour. t
guapka [62]
Time taken for work out was 1/4 hours
let the time taken to walk be x
time spent for jogging will be (1/4-x)

distance=speed×time

distance walked will be:
3.1x miles

distance jogged will be:
5.2(1/4-x) miles

Total distance:
3.1x+5.2(1/4-x)=1.09

solving for x we get
3.1x-5.2x+1.3=1.09
2.1x=0.21
x=0.1
Thus time spent on waling was o.1 hours
time spent on jogging was 0.25-0.1=0.15 hours

Four big water bottles can hold 8 gallons of water. How much water can ten big water bottles hold.
g100num [7]

Step-by-step explanation:

<u>Part 1</u>

To find out the amount of water ten big water bottles can hold, we have to find out how much water is in each water bottle. To do this, we divide the amount we are looking for by the number of items.

8 ÷ 4 = 2

Part 1 answer: Each water bottle can hold <u>2 gallons</u> of water.

<u>Part 2</u>

Now that we know the amount of water in each water bottle, we can find out how much water 10 water bottles can hold. To do so, we multiply our previous answer, 2, by the number of items (10).

2 • 10 = 20

Part 2 answer: 10 water bottles can hold <u>20 gallons</u> of water.

Our final answer: 20 gallons

I hope this helps you!
