the dog weighs 43 pounds

Step-by-step explanation:

dog = 3x-20 = x + 22

cat = x

3x-20 = x+22

3x = x+42 (add 20 to both sides)

A carton has a length of fraction 2 and 2 over 3 feet, width of fraction 1 and 1 over 3 feet, and height of fraction 1 and 1 ove

astraxan [27]

Writing this problem in symbols instead of in words greatly simplifies it:

(2 2/3) * (1 1/5) * (1 1/2)

Write each quantity (inside each set of parentheses) as an improper fraction:

(8/3) * (6/5) * (3/2)

Now multiply the numerators thru: 8*6*3 / 3*5*2

Notice that we can reduce this by dividing the 8 by the 2 and dividing the 6 by the 3: 4*3*3 36
---------- = -----------

At the charity drive , Jeremiah must stuff at least 350 bags with cans of food . He can stuff 4 bags in one minute,and he has 90

Ostrovityanka [42]

4m + 90 = ≥ 350
350 - 90 = 260 ÷ 4 = 65

It will take at least 65 minutes for Jeremiah to complete the task.

Replace the variable with 65 to double check.
4 (65) + 90 = 350

if the cost of a dress is multiplied by 5/8 the price then becomes $30.00 what was the original price

Alik [6]

Let's label the original price of the dress as x. We know that
$x \times \frac{5}{8} = 30$
so that means that we can find x by dividing both sides by 5/8:
$x = 30 \div \frac{5}{8}$
A simple rule for dividing fractions is 'Keep Change Flip'. You keep the first number/fraction the same, you change the ÷ to a × and you flip the second fraction. Through this rule, we can now solve the equation much more easily:
$x = 30 \times \frac{8}{5} \\ x = \frac{240}{5} \\ x = 48$
Therefore, the original price of the dress was $48
