Sophie can type 128 words in 3 minutes. How many minutes will it take her to type 576 words

Alja [10]

Answer:

13. 5 minutes

Step-by-step explanation:

This is a simple proportion problem. Make two fractions where one item is always on the top and the other on the bottom.

$\frac{3 min}{128 words} = \frac{x min}{ 576 words}$

Now, cross multiply (multiply the two numbers diagonal from each other and divide the diagonal with the x value)

576 x 3 = 1, 728

1, 728 / 128 = 13.5

3x+1/5y=7 solve for y

Vladimir79 [104]

Hello!

First, let's write the problem.
$3x+\frac{1}{5}y=7$
Subtract 3x from both sides.
$3x+\frac{1}{5}y-3x=7-3x$
$\frac{1}{5}y=7-3x$
The opposite of division is multiplication, so we are going to multiply in order to undo the fraction.
$5\cdot \frac{1}{5}y=5\cdot \:7-5\cdot \:3x$

Our final answer would be,
$y=35-15x$

Thanks!

Small=9x5=45

Medium=9x7=63

Large=9x12=108

2x= Medium, Large= 3x, Small=x

Small=45x, Medium= 63x2=126x, Large=108x3=324x

45x+126x+324x=495x

£648.45=495x

£648.45÷495=x

£1.31=x
