Hey there,
We know that area is the size of a surface
First of all, <span>To find the </span>area<span> of a rectangle, multiply the length by the width. In this question the length would be 90 meters and the width would be 45 meters.
</span>90 x 45 = Area
90 x 45 = 4050
<span>Area = 4050m</span>²
Answer: B - <span>The sale price is always less than the original price.</span><span>
$7.99 > $5.59
$10.99 </span>> <span>$7.69
$12.99 </span>> <span>$9.09
$15.99 </span>> <span>$11.19
$24.99 </span>> <span>$17.49
$29.99 </span>> $20.99
Answer:
B yes, because every x value corresponds to exactly one y value
Step-by-step explanation:
A function means that each input goes to a different output
Each input goes to only 1 y value
Reorder the terms:
6 + 14x = 15x
Solving
6 + 14x = 15x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15x' to each side of the equation.
6 + 14x + -15x = 15x + -15x
Combine like terms: 14x + -15x = -1x
6 + -1x = 15x + -15x
Combine like terms: 15x + -15x = 0
6 + -1x = 0
Add '-6' to each side of the equation.
6 + -6 + -1x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + -1x = 0 + -6
-1x = 0 + -6
Combine like terms: 0 + -6 = -6
-1x = -6
Divide each side by '-1'.
x = 6
Simplifying
x = 6
60 min = 1 hour
1st we need to know how many times 20 goes in 60 so we will divide.
60 ÷ 20 = 3
Now we will multiply to find the trains speed in miles per hour.
3 × 25 = 75
SO, the train travels 75 miles per hour.
Hope I helped ya!!
