Answer:

7.  x = 5

8. x = 2, y = 6

9. x = 21, y = 39

Step-by-step explanation:

For a parallelogram, the lengths across intersection are equal.

7. For a parallelogram, the lengths across intersection are equal.

So that,

3x = 4x - 5

4x - 3x = 5

 x = 5

8. For a parallelogram, the lengths across intersection are equal.

So that,

2x = 4

x = \frac{4}{2}

x = 2

and

y - 1 = 2y -7

7 - 1 = 2y - y

y = 6

x = 2, y = 6

9. For a parallelogram, opposite angles have equal value.

Thus,

3x = (4x - 21)

3x = 4x - 21

x = 21

and

3y = (y + 78)

3y = y + 78

3y - y = 78

2y = 78

y = \frac{78}{2}

  = 39

y = 39

x = 21, y = 39

olganol [36]

Answer: 1194677035.714285

Step-by-step explanation:

= {(82902 * 6930)+(93945*82902)} / 7

= (574510860 + 7788228390) / 7

= 8362739250 / 7

= 1194677035.714285

Step-by-step explanation:

Set equations equal to each other.

2x+7=-1

Subtract 7 from both sides.

2x = -8

Divide both sides by 2.

x = -4

harina [27]

Answer:

2/14

Step-by-step explanation:

when you scale the numerator and denominator down by 4, you just divide both of them by 4. So since 8 divided by 4 is 2 and 56 divided by 4 is 14, the answer is 2/14
