Answer:
- x = 10
- B. 3/7
Step-by-step explanation:
1. (x - 2)/ 4 - (3x + 5)/7 = - 3
7(x -2) -4(3x +5) = -84 . . . . . . . multiply by 28
7x -14 -12x -20 = -84 . . . . . . . . eliminate parentheses
-5x -34 = -84 . . . . . . . . . . . . . . collect terms
-5x = -50 . . . . . . . . add 34
x = 10 . . . . . . . . . . . divide by -5

2. 1/(1 + 1/(1 - 1/x)) = 4
1 = 4(1 +1/(1 -1/x)) . . . . multiply by the denominator
-3 = 4/(1 -1/x) . . . . . . . eliminate outer parentheses, subtract 4
-3(1 -1/x) = 4 . . . . . . . multiply by the denominator
-3 +3/x = 4 . . . . . . . . eliminate parentheses
3/x = 7 . . . . . . . . . . . add 3
x = 3/7 . . . . . . . . . . . multiply by x/7
Answer:
I think it may be 14.1593% or something around that. If not, forgive me.

Answer:
0.6772
Step-by-step explanation:
Use a z-score table.
P(-0.85 < z < 1.15) = P(z < 1.15) − P(z < -0.85)
P(-0.85 < z < 1.15) = 0.8749 − 0.1977
P(-0.85 < z < 1.15) = 0.6772
To get the multiplicative inverse of any number, just take the reciprocal of that number.
So for 1/4, it is 4/1
= 4/1 = 4
Multiplicative inverse of 1/4 is 4.
Answer:
A and E
Step-by-step explanation:
um for some reason my answer was deleted…
anyways, I think its A and E because the equation should be g = 2/5t and 0.4 is equal to 2/5 so that means that E is also correct.
