The only items in a container A are 150 pencils and 725 pens. The ratio of the number of pencils to the number of pens in contai

Norma-Jean [14]

Answer:

Option E) 8000

Step-by-step explanation:

It is given in the question that the number of pencils and pens in a container A are 150 and 725.

Let the number of pens and pencils in container B are x and y.

As per statement " Ratio of the number of pencils to the number of pens is 2:3"

Equation will be $\frac{x}{y}=\frac{2}{3}$

Or $x=\frac{2}{3}y$ ------(1)

Second statement says "If all pens and pencils of container B are placed in container A then ratio of pencils and pens would be 3:5"

Equation will be $\frac{x+150}{y+725}=\frac{3}{5}$

5(x + 150) = 3(y + 725) [By cross multiplication]

5x + 750 = 3y + 2175

5x - 3y = 2175 - 750

5x - 3y = 1425 ------(2)

Now we put $x=\frac{2}{3}y$

$5(\frac{2y}{3})-3y=1425$

$\frac{10y}{3}-3y=1425$

$\frac{10y-9y}{3}=1425$

$\frac{y}{3}=1425$

y = 3×1425

y = 4275

Now we put y = 4275 in equation 1

$x=\frac{2}{3}(4275)$

x = 2850

Now (x + y) = 2850 + 4275

= 7125

Now Total number of pen and pencils in container A and container B

= 150 + 725 + 7125

= 8000

Therefore, Option E) is the answer

Solve for d:<br> 2d+1/6=6(1/3d+1)

taurus [48]

2d+1/6=2d+6 (I distributed the 6 to what was in the parentheses)
2d-2d=6-1/6 (I subtracted 2d from both sides to get the variables on one side and 1/6 from both sides to get the variables by themselves)
0=35/6 (combined like terms)
0=35/6 is an untrue statement so x doesn't exist

Leon charged $75 at an interest rate of 12.5% how much will Leon have to pay after one month if he makes no payments

OlgaM077 [116]

So basically, let's look at the given. In the problem, Leon is charged a fee of 75. The interest rate would be 12.5 % if he doesn't pay his due amount. So in order to get the total amount that he has to pay if he doesn't pay on time, you just need to multiply 75 with 12.5% or simply 0.125. If you do this, you will get 9.375. After that, you add 9.375 to the principal amount which is 75 and you will get 84.375. So Leon has to now pay a total of 84.375.

I hope this HELP! :)
