What is the value of y in the equation 4(5y –8 –2) = 185 –15?

Answer:

67 im pretty sure because the other vertical is 45 and then 67-22=45 so hope this helps.

Step-by-step explanation:

and ill write more if i want!

Answer:

67

Step-by-step explanation:

The line they are both on is straight so it is 180 degrees.

180 - 135 = 45

Meaning the side with the x is 45 degrees.

45 + 22 = 67

And to check you could do 67 - 22 =45

45 + 135 = 180

Answer: 7/4

Step-by-step explanation:

you would first add 5 to both sides

4x-5+5= -12+5

then simplify

4x= -7

divide 4 on both sides

4x/4= -7/4

and you get x=7/4

Answer:

The answer to your question is:

x = 2

y = 4

Step-by-step explanation:

     4x - 5y = -12       (1)

      -x + 5y = 18        (2)

Solve the system

                                               4x - 5y = -12

                                                 -x + 5y = 18

                                              3x   + 0 = 6

                                               3x = 6

                                                  x = 6 / 3

                                                  x = 2

                  Substitution

                                     4(2) - 5y = -12

                                      8 -5y = -12

                                          -5y = -12 - 8

                                          -5y = -20

                                           y = -20 / -5

                                           y = 4    

The probability of rolling an  odd number the first time and a number greater than 4 the second time is 1/6

The sample space of a single die is

So, the total sample is 6

The odd numbers are

--- 3 odd numbers.

So, the probability of selecting an odd number is:

Simplify

The numbers greater than 4 are

--- 2 numbers greater than 4.

So, the probability of selecting a number greater than 4 is:

Simplify

The probability of rolling an  odd number the first time and a number greater than 4 the second time is calculated as follows:

So, we have:

Hence, the probability is 1/6

Answer: 1/6

Step-by-step explanation:

A die has 6 numbers which are 1, 2, 3, 4, 5 and 6.

Odd numbers in a die = 1, 3 and 6

Numbers greater than 4 = 5 and 6

Probability of rolling an odd number = 3/6 = 1/2

Probability of rolling a number greater than 4 = 2/6 = 1/3

We then multiply both values gotten. This will be:

= 1/2 × 1/3

= 1/6

Therefore, the probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6.
