Let, the number = x
It would be: 8x + 3 = 3(2x-1)
8x + 3 = 6x - 3
8x - 6x = -3 - 3
2x = -6
x = -6/2
x = -3
In short, Your Answer & that number would be -3
Hope this helps!
Answer:
(-3, -8)
Step-by-step explanation:
The point is in the third quadrant, so both coordinates must be negative. -3 represents the x coordinate and -8 represents the y coordinate.
One width and one length is half the perimeter.
90/2 = 45
Let the width = X
the length is 2 times the width so 2X
The sum of the two equals 45"
2X + X = 45
Simplify:
3x = 45
Divide both sides by 3:
x = 15
The width is 15 inches
Length = 30 inches.
Area = Length x width = 15 x 30 = 450 in^2
The area 450 in^2
Answer:
Step-by-step explanation:
126 buttons.....8 two holes for every 4 holes...added = 12
so 8/12 of the total buttons are two hole and 4/12 of the total buttons are four hole
8/12 of 126 = 2/3 * 126 = 252/3 = 84 two hole buttons <==
4/12 of 126 = 1/3 * 126 = 126/3 = 42 four hole buttons <==
