First convert both distances to the same unit. 1 mile is 5280 feet or 1760 yards. Subtract 1760-880 and get 880 yards. Noah swam 880 yards further than Liam ran.

Leave the answer as an improper fraction​
Ghella [55]

Hey there!

ANSWER: \frac{23}{20}

EXPLANATION:

To find the answer to your question, you will need to add.

\frac{3}{4}+\frac{2}{5}

First, multiply the denominator.

5*4=20

So the denominator will be 20.

Now move on to the numerator. Multiply 5 by 3.

5*3=15

Now multiply 4 bu 2.

4*2=8

If you want to get the numerator, add what you got after multiply.

15+8=23

The numerator is 23. So now let's complete the fraction.

\frac{23}{20}

This is your answer!

Hope this helps!

How do you solve:<br>18(18)=x(x+15)
ehidna [41]
Hello!

18(18)=x(x+15)

The parentheses indicate multiplication; the 18(18) on the left side of the equation is 18 * 18. On the right side of the equation, you have x(x + 15); to simplify this, you would distribute the x--that means multiply each term inside the parentheses by x. This is the Distributive Property: a(b + c) = ab + ac. Let's do that.

18(18)=x(x+15)
324= x^{2} +15x

Now, you can subtract 324 from each side to set the equation equal to 0.

324= x^{2} +15x
324-324= x^{2} +15x-324
0= x^{2} +15x-324

This is a quadratic equation; to solve it, we may factor (if the equation is able to be factored) or we can use the Quadratic Formula. Let's see if we can factor. To factor, find two numbers whose sum is 15 and whose product is -324. Since 324 is negative, we know one of the numbers is negative and one of the numbers is positive (a negative times a positive is always negative), and that means one of the numbers is greater than 15...

27 - 12 = 15
27 * -12 = -324

The factored polynomial is: (x + 27)(x - 12).

To find its solutions, set the factors equal to 0 and solve for x.

x + 27 = 0
x = -27

x - 12 = 0
x = 12

Answer:
The solution of 18(18)=x(x+15) is -27 and 12.

Sean has worked 66 hours over the last 10 days without a day off. He worked either a 6 hour day or an 8 hour day. During the 10
marysya [2.9K]
He worked an 8 hour day 3 days.

Let x be the number of 8 hour days he works.  Then 10-x is the number of 6 hour days he works.

8x + 6(10-x) = 66

Using the distributive property,
8x + 6*10 - 6*x = 66
8x + 60 - 6x = 66

Combining like terms,
2x + 60 = 66

Subtract 60 from both sides:
2x + 60 - 60 = 66 - 60
2x = 6

Divide both sides by 2:
2x/2 = 6/2
x = 3

There were 3 days he worked 8 hours.
