Solve the system by substitution -4-y=17 and 4y=x

Mathematics
1 answer:
allochka39001 [22]3 years ago
7 0

Answer:

x = -84

y = -21

Step-by-step explanation:

4 - y = 17

4y = x

Use the first equation to solve for y

4 - y = 17

y = 4 -  17

y = -21

In the second equation, get y on its own.

4y = x

y = x/4

Substitute the new second equation into the new first equation

-21 = x/4

-21 * 4 = x

x = -84

Is 4 a factor of 93 explain your answer using words
Usimov [2.4K]

Answer:

no

Step-by-step explanation:

Here we will show you two different methods you can use to determine if 4 is a factor of 93.

The first method entails simply listing all factors of 93 and then seeing if 4 is one of them. The factors of 93 are 1, 3, 31, and 93. Looking at the list, you see that 4 is not on the list, and the answer to "Is 4 a factor of 93?" is therefore no.

For the second and perhaps easier method, we divide 93 by 4 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 4 is a factor of 93. If the quotient is a fractional number, then 4 is not a factor of 93.

93 divided by 4 is 23.25 which is a fractional number. Thus, once again, the answer to "Is 4 a factor of 93?" is no.

Solve for X<br> 1) 8(1 + 5x) + 5 = 13 + 5x
marusya05 [52]

Answer:

X=0

Step-by-step explanation:

8(1  \times  5x) + 5 = 13 + 5x  \\ 8 + 40x + 5 = 13 + 5x \\ 40x + 13 = 13 + 5x \\ 40x - 5x = 13 - 13 \\ 35x = 0 \\ x = 35 \times 0 \\ x = 0

If you were to roll the dice one time what is the probability it will NOT land on a 2?
Nikitich [7]

Answer:

5 / 6

Step-by-step explanation:

Given that:

Probability that a dice rolled once will not land on 2

Probability = required outcome / Total possible outcomes

Total possible outcomes = (1, 2, 3, 4, 5, 6)

Required outcome = 2

P(not land on 2) = 1 - p(land on 2)

P(land on 2) = 1/6

P(not land on 2) = 1 - 1/6

P(not land on 2) = 5/6
