Answer:

24 miles

Step-by-step explanation:

we know that

The speed is the ratio of the distance by the time

Let

d -----> the distance in miles

t -----> the time in hours

s ----a. the speed in mph

s=\frac{d}{t}

we have

s=6\ mi/h

t=4\ h

substitute in the formula and solve for d

6=\frac{d}{4}

d=6(4)=24\ mi

The largest solution of x2−x=6 is
trapecia [35]
The left side of the equation subtracts x from 2x. 
That means 1x, or just simply x, is left on the left side. 
We now have this:   x = 6 
So, x is 6. Hope this helps!

three sets of the sum of a number and four are added to the sum of seven times the same number and thirteen
almond37 [142]

The algebraic expression for given statement is: 10x + 25 or 3(x + 4) + (7x + 13)

<em><u>Solution:</u></em>

Given the statement:

Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen

Let us first understand the given statement,

Let the number be "x"

" sum of a number and four" means x + 4

"Three sets of a sum of a number and four" translated to 3(x + 4)

"sum of seven times the same number and thirteen" means 7x + 13

<em><u>Thus the algebraic expression for given statement is:</u></em>

3(x+4)+(7x + 13)

<em><u>Using distributive property in above expression</u></em>

a(b+c) = ab + bc

Therefore,

3(x+4)+(7x + 13) = 3x + 12 + 7x + 13

<em><u>Combine the like terms</u></em>

3(x+4)+(7x + 13) = 10x+25

Thus the required expression for given statement is: 10x + 25 or 3(x + 4) + (7x + 13)

There are 100 balloons in total the ratio between the yellow and blue balloons is 8 to 12 how many are yellow
Virty [35]

If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio.

Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication.

Finally, solve for x and if you had 100 balloons, you will have 40 yellow balloons.
