<h3>Algebra Word Problems</h3>
Weight of billy's dog = 30 pounds
Weight of Ruth's dog = 2/6 of billy's dog = 2/6 * 30 = 10 pounds
Thus, total weight of both billy and ruth's dog is;
Total weight = 30 + 10

He's driving 42mph. 42m/60h=0.7mpm. 12 minutes x 0.7 mile per minute= 8.4 miles. 21-8.4=12.6 miles left . 12.6 x 0.7= 8.86 minutes left or about nine
To properly make the comparison between the weights of the books, we compute for their weights in similar units. For this item, we need to convert the weight of the first book to kilogram.
conversion:
Book 1 : (7.49 lbs) x (0.4535924 kg / 1 lb) = 3.397 kg
Since the second book weights 3.91 kg, it is heavier than the encyclopedia. Subtracting the weight of the first book from the second one will give us an answer of 0.51 kg. Thus, the answer to this item is letter D.
Answer:
The Solution set is (x,y){(2,5)}
Step-by-step explanation:
The given equation is:
6x+4y=32
-6x+4y=8
We will use the elimination method:
By this method we will eliminate the variable x.
6x+4y=32
-6x+4y=8
________
8y=40
Divide both the sides by 8
8y/8=40/8
y=5
Now substitute the value of y in equation 2:
-6x+4y=8
-6x+4(5)=8
-6x+20=8
Move the constant value to the R.H.S
-6x=8-20
-6x= -12
Divide both the terms by -6
-6x/-6 = -12/-6
x= 2
The Solution set is (x,y){(2,5)}....
The actual length of the row can be calculated by the concept of ratio and proportion. Using the scaling of the garden plot given in this item and the length of the row in the drawing,
L = (3 in)(17 ft / 2 in)
Simplifying,
<em> L = 25.5 ft</em>
The answer to this item is 25.5 ft.
