Answer:

the answer is x+7y=14

Step-by-step explanation:

3x-7+5=x+6

First, simplify on boths sides. On the left side you can add -7 and 5. Then you get the equation:

3x-2=x+6

Next, you have to rearrange the equation in such a way that x is on the left side and numbers on the right side. Since we don't like the x on the right side, we substract x on both sides. 2x are left on the left side.

2x-2=6

Now, we have to get the number -2 on the other side. So we add 2 on bothe sides. Since 6+2=8, we get

2x=8

Now, we divide both sides by the number in front of the x:

X=4

Answer:

Step-by-step explanation:

women=85+32=117

men=70+51=121

total=117+121=238

a. P(woman)=117/238

b. P(woman or summer)=p(woman)+P(summer )-P(woman and summer)

=117/238+155/238-85/238

=187/238

c. P(woman and summer)=85/238

Please answer the question from the picture above

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

https://www.coolmath4kids.com/math-help/fractions/adding-and-subtracting-fractions-different-denominators

For example:
1/2 + 1/3

We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators, 2 and 3.

The LCM of 2 and 3 is 6. So, our LCD 6.

We need to make this our new denominator...

Change the 1/2:

1 x 3 over 2 x 3 = 3/6

Change the 1/3:



1/2 + 1/3 = 3/6 + 2/6

Now we can do it!

(3+2)/6 = 5/6

A standard deck of has 52 cards, and contains 13 cards of each of the four suits: diamonds, spades, hearts, and clubs. What is t
Verizon [17]

Answer: \frac{13}{51}

Step-by-step explanation:

Given: Number of cards in a standard deck = 52

If we already chosen a diamond card, then the number of cards left in the deck =52-1=51

The number of spades remains same = 13

Now, the probability that you choose a spade, given that you have already chosen a diamond is given by :-

P(Spade|diamond)=\frac{13}{51}

Hence, the the probability that you choose a spade, given that you have already chosen a diamond =\frac{13}{51}
