A dog weighs two pounds less than three times the weight of a cat. The dog also weights twenty-two more pounds than the cat. Wri
Solnce55 [7]

Answer:

the cat weighs 21 pounds.

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)

2x = 42 (subtract x from both sides)

x = 21

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
