You would start by adding the 18 to the 2 to give you 20. then you would subtract x from the 6x to give you 5x. then your equation should be 5x=20, then you divide 20 by 5 and that give you 4. So x would equal 4. x=4
Answer:
= 78
Step-by-step explanation:
x² + 5x - 6
when x = 7:
7² + 5*7 - 6
= 49 + 35 - 6
= 84 - 6
= 78
Answer:
your top choice is your answer with positive one on the front of the equation
Answer:
2/7 = 29% (nearest percent)
Step-by-step explanation:
Calculate the totals and add them to the table:

<u>Probability Formula</u>

Let P(A) = probability that the student is a freshman
Let P(B) = probability that the student is male
Use the given table to calculate the probability that the <u>student is male</u>:

And the probability that the <u>student is a freshman </u><u>and </u><u>male:</u>

To find the probability that the student owns a credit card given that the they are a freshman, use the conditional probability formula:
<u>Conditional Probability Formula</u>
The probability of A given B is:

Substitute the found values into the formula:

Therefore, the probability that the student is a freshman given they are male is 29% (nearest percent).

Since there are a lot of questions, let me just show you how to do one.
1/4×3/5
First multiply from left to right, so 1×3 is 4 and 3×5 is 15, so the answer is 4/15. If the final fraction can be reduced, divide it by the GCF and you'll get the answer.
