Hi there!
Let the width of the rectangle be called x. Then the length of the rectangle is 2x. We get the following perimeter:
Collect the terms
Divide by 6
Therefore, the width of the rectangle is 21 feet and the length is 2 × 21 = 42 feet.
Answer
Y=1/2x-3
Explanation
The general equation of a straight line is the form
Y = mx + c
where m ⇒slope of the line.
In the equation given, we make y the subject of the formula then we arrange the equation to resemble y=mx+c.
6y-3x=-18
6y = -18 + 3x
y = -18/6 + 3x/6
-3 + (1/2)x
y = (1/2)x - 3
10^2+14^2=296
Square root of 296
17.20
Answer:
1. The equation to solve this equations is:
= 3x = 231
2. The three integers are 77, 78 and 79.
Step-by-step explanation:
The sum of 3 consecutive integers = 234
let x = first integer
let x+1 = second integer
let x+2 = third integer
Therefore,
= x + x + 1 + x + 2 = 234
simplified to:
= 3x = 231
b) Adding three consecutive numbers adds the smaller number to itself three times, and then adding 1 for the second number, and two for the third number. So, the sum of the three consecutive numbers is divisible by 3. Therefore, to get the second (or middle) number, divide the total by 3, and then subtract 1 and add 2 to get the first and the third numbers, respectively.
