The diagram below represents the measurements of Jennie’s yard. The yard’s width is x feet shorter than its length. If the area of the yard is 540 square feet, how many feet shorter than the length is the width? A yard with a length of 30 feet and a width of (30 minus x) feet. Which equation represents the scenario? 30 + (30 – x) = 540 540 – 30 = 30 – x 30(30 – x) = 540 540 – (30 – x) = 30
Answer:
30(30 - x) = 540

Answer: The speed of the car is 45.3 miles per hour.
Step-by-Step Explanation: Let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200
=> x = 45.3
Answer:
The car was traveling at an average speed of 45.3 miles per hour.
Step-by-step explanation:
We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.
We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):
30.2/40=x/60
We then cross multiply:
30.2x60=40(x)
1,812=40(x)
Divide each side by 40
1,812/40 = x
x=45.3

Is there a specific rule to follow when dividing simplified fractions? i mean if you were to have the numerator and demoninator you divide them by two four? or is it optional?
Answer:
Step-by-step explanation:
This method consists of multiplying the numerator of the first fraction by the denominator of the second fraction and then writing the answer in the resulting fraction’s numerator.
Next, we multiply the denominator of the first fraction by the numerator of the second fraction, and then write the answer in the resulting fraction’s denominator*.
Lastly, we simplify the final fraction.
For example, in order to divide the fraction
dividing fractions
We multiply the numerator of the first fraction (3) by the denominator of the second fraction (10). This gives us the numerator for the final fraction: 3 x 10 = 30.
Next, we multiply the denominator of the first fraction (4) by the numerator of the second fraction (6). This gives us the denominator of the final fraction: 4 x 6 = 24.
dividing fractions
The last step is to simplify the fraction. Since both numbers are multiples of 6, we can divide the numerator and denominator by 6.
30 ÷ 6 = 5
24 ÷ 6 = 4
Therefore, the result of the division is 5/4.
dividing fractions
Method 2 of dividing fractions: Inverting and multiplying
Step 1: Invert the second fraction. That is, swap the numerator for the denominator.
Step 2: Simplify any numerator with any denominator.
Step 3: Multiply across.
For example, we are going to divide:
dividing fractions
Step 1: We invert the second fraction 6/4. This becomes 4/6.
Step 2: We simplify the numerators with the denominators.
Numerators are:
12 = 2 x 2 x 3
4 = 2 × 2
Denominators are:
5 = 5
6 = 2 × 3
We can simplify both from numerator and denominator a 2 and a 3. We call this process “cross canceling” if one numerator has a common factor with the other denominator.
And we multiply across:

30x+ 600 ≥ 1,500
Answer:
x ≥ 30
Step-by-step explanation:
30*30 = 900 and when we add 600 to that, we get 1,500 which is the lowest possible number for the left side of the equation to equal. If x equals anything above 30, then it will automatically equal a number greater than 1,500 when added to 600.
(sorry this is confusing, I'm not very good at explaining things. I hope it helped anyway)
Answer:
x > 30
Step-by-step explanation:
replace > with=
30x +600=1500
take 600 to the other side
30x=1500-600
30x=900
x=30
therefore x > 30
