Answer:
25
Step-by-step explanation:
Use PEMDAS
do the powers first then the multiplication then the addition then the subtractions
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.
Answer:
The number of yards in 5 miles will be: 8800 miles
Step-by-step explanation:
- The double numbers line shows the ratio of yards to miles.
From the number line, it is clear that
- at 2 miles, the number of yards is 3520.
Thus,
The unit rate = 3520 yards / 2 miles
= 1760 yards / per mile
Thus, the number of yards in 5 miles will be:
1760 × 5 = 8800 miles
Therefore, the number of yards in 5 miles will be: 8800 miles
The numerator represents a number of equal parts, and the denominator is how many of those equal parts make up a whole.
