49

Step-by-step explanation:

So it seems theres some sort of pattern. When you mutiply 7 by 3 you get 21. When you multply 5 by 7 you get 35. So basically 7 times 7 would be 49. Correct me if im wrong.

Which system of equations has the solution (4,−2)?
Marat540 [252]

Answer:

A)

Step-by-step explanation:

To find the answer we must solve each of the systems separately. Starting with the first one:

x + y = 2

2x - y = 10

We must find what x or y is equal to and then replace it in the second equation. I'll go with y as it seems easier:

x + y = 2

y = 2 - x

Now that we found y we replace it in the second equation this way. Be careful with the signs, the minus with change our signs:

2x - (2 - x) = 10

2x - 2 + x = 10

3x = 12

x = 12/3

x = 4

Now that we have x, we replace the variable with its value in one of the equations. Again, for simplicity I'll go with the one that seems easier.

4 + y = 2

y = 2 - 4

y = - 2

Step 2: Multiply each point by 5.

and record thise points so we have

Write as an expression: a number that is equal to twice as much as x
lesantik [10]

Let's call the number we're looking for y. We know that y is twice as much as x.


Twice as much as a number simply means the double of that number, and in turn the double of a number means to muliply that number by 2.


So, in order to obtain y, you have to multply x by 2. In formula, you have


y = 2\cdot x or simply y = 2x
