To solve for x in the first equation, we can set up the proportion:
(X + 2)/8 = 1.6/1
Cross multiply:
1 (X + 2) = 8 1.6X + 2 = 12.8X = 12.8 - 2X = 10.8
Therefore, x = 10.8.
To solve for x in the second equation, we can set up the proportion:
15/5 = (x - 1)/3.1
15 3.1 = 5 (x - 1)46.5 = 5x - 55x = 46.5 + 55x = 51.5x = 51.5 / 5x = 10.3
Therefore, x = 10.3.
To solve for x in the first equation, we can set up the proportion:
(X + 2)/8 = 1.6/1
Cross multiply:
1 (X + 2) = 8 1.6
X + 2 = 12.8
X = 12.8 - 2
X = 10.8
Therefore, x = 10.8.
To solve for x in the second equation, we can set up the proportion:
15/5 = (x - 1)/3.1
Cross multiply:
15 3.1 = 5 (x - 1)
46.5 = 5x - 5
5x = 46.5 + 5
5x = 51.5
x = 51.5 / 5
x = 10.3
Therefore, x = 10.3.
