The equation would be x+7x+12x = 100
solving gives x=5
12×5=60
7×35
5+35+60=100
The age/answer is 60
Y = -5x + 1
x = 1 , y = -4
x = 2 , y = -9
x = 3 , y = -14
so the answers are
(1,-4)
(2,-9)
(3,-14)
Step-by-step explanation:
Greatest is starting by 8 and the littlest is 1.
Find the x and y intercepts or any other 2 points. (I advise you finding the y intercept though.)
then calculate for slope using:
y(2) - y(1)
________
x(2) - x(1)
The (2) and (1) are not exponents they are small numbers at the bottom of the numbers.
The slope is: 4
Since the sum of the angles is 360°, we need to divide 360 with the number of sides that a polygon has.
360/18=20; this polygon has 20 sides.
