Let x = Darlene's dog's weightlet y = Leah's dog's weight x = 5yx + y = 84 so, 5y + y = 84, which means 6y = 84 so, y = 84/6 = 14x = 5(14) = 70 Darlene's dog = 70 lbs, Leah's dog = 14 lbs.<span> </span>
Answer:
D. 80 cubic inches
Step-by-step explanation:
Arranged in five rows of four => we can say the length, depth and width as 5,4,4
So, the volume is equal to 5 x 4 x 4 = 80 cubic inches
Sorry that this answer might not make sense to you, I just can't think of any better explanation.
The formula for the area of a circle is pi times the radius squared. Here are the steps to solving this problem.
1. First, find the radius. Since the radius is allows half of the diameter, then we divide the diameter by two. 50/2= 25
2. Next, we square the radius. 25^2= 625
3. After that we multiply 625 ft by pi(3.14).
625 times 3.14= 1962.5
4. The last step is to round the the answer to the nearest square foot. Since 5 is at the end, we round up to 1,963.
So the answer is 1,963 ft^2.
These are all linear equations, because all of the variables are raised to the positive FIRST power: <span>-4v+2w=7, x/4=y, x=-5
The last equation, </span><span>2/x +3/y=6, is not linear, because the powers of the variables are negative:
2x^(-1) + 3y^(-1) = 6 NON LINEAR</span>
