Answer:
y = (C -0.99n)/48
Step-by-step explanation:
Undo what is done to y, in the reverse order. We have y multiplied by 48 then added to 0.99n. So, we must add the opposite of 0.99n and multiply that result by the reciprocal of 48.
C = 48y + 0.99n . . . . . . given
C - 0.99n = 48y . . . . . . add -0.99n
(C -0.99n)/48 = y . . . . . multiply by 1/48
Answer:
117.5 or 235/2
Step-by-step explanation:
We can set up an equation for this problem:
Lets Joe's weight be x
then:
2x -5 = 230
therefore:
2x = 235
x = 117.5 or 235/2
Answer:
23- 2x
Step-by-step explanation:
Twice a number is 2 and "x" represents "a number"
Key words: Twice, Difference (subtraction)
No, it won’t work. The greatest common factor between 45 and 27 is 9, but 45-27=18. So it cannot work.
Divide -3
-3/-3a = 15/-3
a = -5
