Answer:

Step-by-step explanation:

first, we would set up an equation. since they say that a number is subtracted from 25, let x represent that number and say 25-x. on the other side of the equation, since it says the difference would be 8 less than twice that number, we would say 2x-8 because twice x would be 2x and we'd subtract 8 from that.

the equation would look like this:

25-x=2x-8

next, we would solve. first get the x to one side of the equation:

25=3x-8

then, get the 3x by itself:

33=3x

finally, solve for x by dividing both sides of the equation by 3:

11=x

x=11.

The number is 11.

Answer:

Chuck's rate of travel = 63mph

Step-by-step explanation:

Given chuck travels 252 miles and dana travels 228 miles. Given that they both take same time to travel .

Let the travelling time be T.

Also given that the speed of chuck is 6mph greater than that of dana's.

let the speed of chuck be x. Now

Speed = $\frac{distance }{time}$

x= $\frac{252}{T}$

Now for Dana's speed

x-6= $\frac{228}{T}$

When we divide both the equations we get

$\frac{x}{x-6}=\frac{252}{228}$

$\frac{x}{x-6}=\frac{63}{57}$

x=63mph

Explain how showing fractions with models and a number line are alike and different

Leni [432]

You use a number line to see what is greater and less than.
And use a model to visualize it more.
And they are alike because they can both help in the same way but for different people.

Hugo received $100 for his birthday. He

blsea [12.9K]

Answer:

18 weeks

Step-by-step explanation:

Total amount of money saved up to buy the printer is T(w), where w is the number of weeks.

Then T(w) = $100 + ($20/wk)w

Setting this equal to $460, we solve the resulting equation for w to determine the number of weeks it took Hugo to save up $460 total:

$460 = $100 + ($20/wk)w, or

$360 = ($20/wk)w, or

w = $360/($20/wk) = 18 weeks
