The first step is to do the distributive property to get rid of the parenthesis...youd end up with:
2x + 14 = 36
Answer:
x = 6
Step-by-step explanation:
~Given
4(x + 5) = 9x + 4x - 34
~Distributive Property (left side) and Combine Like Terms (right side)
4x + 20 = 13x - 34
~Subtraction Property of Equality
4x = 13x - 54
~Subtraction Property of Equality
-9x = -54
~Division Property of Equality
x = 6
Best of Luck!
Answer:
C.
Step-by-step explanation:
To answer this, we first have to make common denominators. to do this, we do (5/4) x 5 and (3/5) x 4, to get new fractions, 25/20, and 12/20. then, we can subtract 25/20 and 12/20 easily to get the remaining liters, 13/20. Then, to pick the right model, we need to find which box(es) has 20 squares in it, which are Boxes A and C. Now, we can just count which one contains 13 filled-in squares, which is Box C. So that is our answer, C.
Answer:
a. 16%
Step-by-step explanation:
The difference from the mean is ...
(x - µ) = 4420 lb -3550 lb = 870 lb
Then the minimum Z-score of the traffic of interest is ...
(x - µ)/σ = (870 lb)/(870 lb) = 1

The "empirical rule" tells you that 68% of a normal distribution is within 1 σ (Z = ±1) of the mean. If 68% is inside that range, then the remaining 32% is outside that range. The normal distribution is symmetrical about the mean, so half that quantity is below Z = -1, and the other half, 16%, is above Z=1.
About 16% of the cars have weights more than 4420 pounds.
