a box half full of apples weighs 40kg and the same box one fifth full weighs 22kg. what does the box weigh when empty?

likoan [24]

So in order to answer your question we calculate 40 - 22 wich gives us the answer of 18, so now we can say that 4/5 of apples weight 18 so now 18 / 4 = 4,5; 4,5 * 5 = 22,5 wich is the weight of apples you can put in the box, to know the answer we deduct the greatest weight of apples only from the weight of the box with those apples so, 40 - 22,5 = 17,5
so the answer to your question is 17,5
i hope i helped you

Six times a number is 45 greater than the the product of the number and -3. Find the number.

blagie [28]

Let us try to formulate the expressions one by one.

let the number be x.

Step 1:

six time the number is 6*x = 6x

Step 2:

product of the number and -3 is -3x

Step 3:

now let us make equation for it:

$6x = -3x +45$

adding 3x on the left side,

$6x+3x = 45$

$9x = 45$

dividing right side by 9

x=45/9 = 5

So the number is x=5
