Answer:
1-3x/5
Give me brainiest
Step-by-step explanation:
Answer:
<u>28.5 and 32.5</u>
Step-by-step explanation:
<em>create an equation to solve:</em>
x + (x+4) =61
2x + 4 = 61 combine like terms
2x = 57 subtract 4 from both sides
x = 28.5 divide 2 from both sides
28.5 is the smaller number
the larger number is 4 more so:
28.5 + 4 = 32.5
32.5 is the larger number
check your work:
28.5 + 32.5 = 61
So it gives you the diameter but you need the radius of the circle to find the area so to find the radius you just divide the diameter by two. the formula for the area of a circle is A=pi*r^2 so you just multiply 3.14 by 3 squared so you just put it in the calculator as A=3.14*3^2 and you get 28.26 hope this helped
Let us assume the first number = x
Then the second number = 5x -2
The third number = x + 4
The total number that needs to be divided into three parts is 219
Then we can write the equation as
x + 5x - 2 + x + 4 = 219
7x + 2 = 219
7x = 219 - 2
7x = 217
x = 217/7
= 31
Then
First number = 31
Second number = 5x - 2
= (5 * 31) - 2
= 155 -2
= 153
Third number = x + 4
= 31 + 4
= 35
So the three numbers are 31, 153 and 35.
