Based on the total amount of stamps that Noah has, we can calculate that those showing famous athletes number<u> 625 stamps. </u>

The percentage that shows famous athletes is:

<em>= 100% - U.S. Presidents - animals </em>

= 100% - 30% - 45%

= 25%

With a collection of 2,500 stamps, the number that is for famous athletes is:

= 2,500 x 25%

= 625 stamps

In conclusion, 625 stamps show famous athletes.

Essential: Solve the proportions<br> step by step ​
vazorg [7]

Answer:

The value of r=\frac{-106}{47}

The value of x=\frac{83}{32}

Step-by-step explanation:

Given that,

A) \frac{2r-2}{7r+10} = \frac{9}{8}

Now,

\frac{2r-2}{7r+10} = \frac{9}{8}

8(2r-2)=9(7r+10)

16r-16=63r+90

-16-90=63r-16r

-(16+90)=47r

-106=47r

r=\frac{-106}{47}

B) \frac{x+4}{9} = \frac{3(x-2)-1}{5}

Now,

\frac{x+4}{9} = \frac{3(x-2)-1}{5}

5(x+5)=9[3(x-2)-1]

5x+25=9[3x-6-1]

5x+25=9[3x-7]

5x+25=27x-63

25+63=27x+5x

83=32x

x=\frac{83}{32}

Two cars leave Denver at the same time and travel in opposite directions. One car travels 10 mi/h faster than the other car. The
mestny [16]
Recall your d = rt, distance =  rate * time

let's say we have two cars, A and B, B has a speed rate of "r", so A is the faster one and has a speed rate of " r + 10 "

they both are 300 miles apart after 3hrs, after 3hrs, car has been running for 3hrs, and car B has also been running for 3hrs, so their time is the same

we know their distances added up, is 300miles, so if car B covered say, "d" distance on those 3hrs, car A covered the slack, " 300 - d "

\bf \begin{array}{lccclll}&#10;&distance&rate&time\\&#10;&-----&-----&-----\\&#10;\textit{car A}&300-d&r+10&3\\&#10;\textit{car B}&d&r&3&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;\begin{cases}&#10;300-d=(r+10)3\\&#10;\boxed{d}=3r\\&#10;----------\\&#10;300-\boxed{3r}=3(r+10)&#10;\end{cases}

solve for "r"

413 divided by 14 <br> How do you it?
guajiro [1.7K]
You can either do this on the calculator, or in your head. As its a larger number, it is worth doing it on the calculator.
413/14= 29.5
The alternative method is to list all of the tens multiples, and the smaller multiples when you're getting close to the answer, and this will be able to help you.
14x10= 140
14x20=280
14x30= 420 (which is slightly too big)
14x29= 406 (slightly too small)
14x29.5= 413

Hope this helps :)
