Answer:
x = 4/9
Step-by-step explanation:
7(6x + 1) = 3(9 - x)
First, distribute the 7 and the 3 across the parentheses.
42x + 7 = 27 - 3x
Now, combine the variables. (Add 3x)
45x + 7 = 27
Now, combine the constants. (Subtract 7)
45x = 20
Now, isolate the x. (Divide by 45)
x = 20/45
Simplify.
x = 4/9

Answer: Katie is scuba diving at an altitude of -14 ft below sea level. She goes up 5 ft. What altitude is Katie at after she goes up 5 ft?
Step-by-step explanation:
a because the cubed root of 27 is 3
or 3x3x3 is equal to 27
8 = 2 x 2 x 2
11 = 11
12 = 2 x 2 x 3
LCM = 2 x 2 x 2 x 3 x 11 = 264
