Answer:
Step-by-step explanation:
let x,y be the sides of court.
2(x+y)=90
x+y=90/2=45
y=45-x
xy=500
x(45-x)=500
45x-x²=500
x²-45x+500=0
x²-25x-20x+500=0
x(x-25)-20(x-25)=0
(x-25)(x-20)=0
x=25,20
when x=25
y=45-x=45-25=20
when x=20
y=45-20=25
sides are 25 ft,20 ft.
50 Is the answer.........
4(-2)-3 = -8-3 = -11
Answer: -11
Answer:
First number: -39
Second number: -37
Step-by-step explanation:
An odd number can be written as
where n is a whole number.
Let's call our first number 2n+1.
Our second, consecutive number will be 2 more than our first number, since it has to be odd. All numbers go: odd -> even -> odd -> even. If we have an odd number, and add 2, we'll get the next odd number.
First number: 2n+1
Second number: 2n+1+2 = 2n+3
The sum of these two numbers, 2n+1 and 2n+3 will be -76.
(2n+1) + (2n+3) = -76
2n + 2n + 1 + 3 = -76
4n + 4 = -76
4n = -80
n = -20
Since our first number is 2n+1:
2 * (-20) + 1 = -40 + 1 = -39
First number: -39
Our second number is 2n+3, or 2 more than our first number.
-39 + 2 = -37
Second number: -37
We can double check this:
-39 + (-37) = -39 - 37 = -76
Answer:
12.5%
Step-by-step explanation:
Step1. Determine the points Matthew had during playoff by subtracting points made during regular season from total points in season.
168 points this season
- <u>147 points regular season </u>
21 points scored in playoff
Step 2. Get the percentage, by dividing playoff points over total points in season
21 ÷ 168 = 0.125
Step 3. Multiply it by 100 to get the percentage equivalent from decimal.
0.125 x 100% = 12.5%
