This problem requires a system of equations.
Let x be the length and y be the width.
xy = 980 x = 5y
Substitute 5y for x.
5y(y) = 980
5y² = 980
y² = 980/5
y² = 196
y = √196
y = 14 feet
Substitute 14 for y.
x = 5y
x = 5(14)
x = 70 feet
The length is 70 feet.
<u>Answer:</u>
<u>Step-by-step explanation:</u>
Distance traveled by a car between two cities = 1/6 distance
Time taken to travel between the two cities = 3/5 hours
Therefore, to find how much of the distance the car can travel in 1 hour, we need to divide the given distance by the given time to get:
(
) ÷ (
)
Change the later fraction to its reciprocal to solve:
× 
=
Therefore, in one hour, the car can travel 5/18 of the distance.
To solve for the x, distribute first the numerical coefficients to the terms on the parentheses. This becomes,
7x - 21 = 4x + 20
Transpose all the terms with x and the constant on either sides of the equation,
7x - 4x = 20 + 21
3x = 41 ; x = 41 / 3
Thus, the answer is x = 41/3 which is fourth among the choices.
30 is A to the second power 31 is X to the first power 32 is just M
Answer:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.
