Answer:

x-2x = -3 and x = 3

Step-by-step explanation:

Given the expression

y=x+5.... 1

y-2x=2.... 2

Substituting the first equation into the second we will have;

From 2;

y -2x = 2

x+5-2x = 2

x-2x +5 = 2

x-2x = 2-5

x-2x = -3

-x =-3

x =3

Hence the required equation is x-2x = -3 and x = 3

sammy [17]
Here you need to find the greatest common factor for each number that they have in common.

48 is same as :

4 \times 12

64 is same as :

4 \times 18

So there will be 4 favor bags and each one will have 12 markers and 18 stickers.

I hope this helps you :)

A system of equations is shown below 5x +2y =-15 2x - 2y =-6 what is the solution to the problem
Citrus2011 [14]

Answer:

(-3, 0)

Step-by-step explanation:

Let's solve this system using the elimination by addition/subtraction method.  Begin by writing the two equations one above the other:

5x +2y =-15

2x - 2y =-6

Notice that the y terms cancel each other out:

5x +2y =-15

2x - 2y =-6

------------------

7x        = -21

Dividing both sides by 7 results in x = -3.

Subbing -3 for x in either of the given equations leads to finding y:

5(-3) + 2y = -15, or -15 + 2y = -15.  This results in 2y = 0, or y = 0.

The solution is (-3, 0).

Question 39/50
KatRina [158]

Using it's concept, it is found that there is a 0.64 = 64% probability that neither flight is delayed.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, there are 2 flights, each with a 0.8 probability of being on time. The flights are independent, hence the probability that both are on time is given by:

p = 0.8 x 0.8 = 0.64.
