Penelope’s Printing Press promptly sails 5-Cent pencils and 10-cent pens to the public. It sold 1000 writing utensils and took i

Bumek [7]

Answer:

Number of pens and pencils sold are 490 and 510 respectively.

Step-by-step explanation:

Let, number of pens = x and the number of pencils = y.

It is given that,

Cost of one pen = 10 cents = 0.1 dollar

Cost of one pencil = 5 cents = 0.05 dollar

As, the total number of writing utensils sold are 100. So, we have,

$x+y=1000$

Also, the total sales is $74.50 gives,

$0.1x+0.05y=74.50$

Thus, the system of equations is,

x + y = 1000 .................................... (1)

0.1x + 0.05y = 74.50 .....................(2)

Multiply (1) by 0.1 and subtract both the equations, we get,

0.05y = 25.5 i.e. y= 510

So, x= 1000- 510 i.e. x= 490.

So, the number of pens and pencils sold are 490 and 510 respectively.

Two cars are traveling down the highway with the same speed. If the first car increases its speed by 1km/hr, and the other car d

Olegator [25]

Answer:

The speed of the cars is $32 \frac{km}{h}$

Step-by-step explanation:

First we must first have the clear concept that $speed=\frac{distance}{time}$ or $s=\frac{d}{t}$

Our question is the speed of the cars then the variable to clear will be s.

Let's raise the equation for each car taking into account that we have the following data:

Car 1: $s_{1}=s+1$ , $t_{1}=2$ and $d_{1}= d_{2}$

Car 1: $s_{2}=s-10$ , $t_{2}=3$ and $d_{1}= d_{2}$

The two cars travel the same distance so we will raise the distance formula for each car and then match them.

Car 1

$d_{1}=s_{1}*t_{1}$

$d_{1}=(s+1)*2$

$d_{1}=2s+2$

Car 2

$d_{2}=s_{2}*t_{2}$

$d_{2}=(s-10)*3$

$d_{2}=3s.30$

$d_{1}=d_{2}$

$2s+2=3s-30$

$2+30=3s-2s$

$32=s$

The speed of the cars is 32 km/hr

15 is what percent of 5

fiasKO [112]

15=5(y)
Divide both sides by 5.
3=y
Because it is not a decimal that means it is 300% not 30%. 15 is 300% of 5.
