3 times x minus 2/5 =8/5 what is x equal to

Hello Jay

4=-x-y

2x-y=10

We need to solve 4=-x-y for x

Now add x to both sides

4+x=-x-y+x

x+4==-y

Add -4 to both sides

x+4-4=-y-4

x=-y-4

Now we need to substitute -y-4 for x in 2x-y=10

2x-y=10

2(-y-4)-y=10

To find the result of this factor we need to simplify

-3y-8=10

Add 8 to both sides so we can start finding the y value

-3y-8+8=10+8

-3y=18

Divide both sides by -3 so we can find the y value

-3y/-3=18/-3

y=-6

Now let's find the x value by substitute -6 for y in x=-y-4

x=-y-4

x=-(-6)-4

x=2

Answer: x=2 and y=-6

I hope that's help:0

Answer:

4 3/5

Step-by-step explanation:

Change 6 3/4 into 6 15/20

Subtract 6 15/20 by 2 3/20 = 4 12/20

Simplify by dividing both numerator and denominator by 4.  Answer is 4 3/5

Answer:

23/5

Step-by-step explanation:

6 3/4=27/4

2 3/20=43/20

27/4-43/20=135/20-43/20=92/20=23/5

Answer:

30

Step-by-step explanation:

Adjacent angles of a parallelogram add up to 180 degrees, meaning that (3x)+(x+60)=180 degrees. You can use this to set up the following equation:

3x+x+60=180

4x=120

x=30 degrees. Hope this helps!

Final answer:

In a parallelogram, opposite angles are equal. Therefore, set 3x (angle A) equal to x + 60 (angle D). Solving for x, we get x = 30.

Explanation:

In this case, we're working with a parallelogram, and one of the properties of a parallelogram is that its opposite angles are equal. That means that ∠A is equal to ∠D. So we set (3x) equal to (x + 60).

To determine the value of x, we can solve this equation:
3x = x + 60. Subtract x from both sides to get 2x = 60, then divide by 2 to get x = 30.

So, the value of x that makes ABCD a parallelogram is 30.
