Answer:

x = -1 , y = 1

Step-by-step explanation:

Solve the following system:

{5 x + 3 y = -2 | (equation 1)

3 x + 2 y = -1 | (equation 2)

Subtract 3/5 × (equation 1) from equation 2:

{5 x + 3 y = -2 | (equation 1)

0 x+y/5 = 1/5 | (equation 2)

Multiply equation 2 by 5:

{5 x + 3 y = -2 | (equation 1)

0 x+y = 1 | (equation 2)

Subtract 3 × (equation 2) from equation 1:

{5 x+0 y = -5 | (equation 1)

0 x+y = 1 | (equation 2)

Divide equation 1 by 5:

{x+0 y = -1 | (equation 1)

0 x+y = 1 | (equation 2)

Collect results:

Answer: {x = -1 , y = 1

Plz help me please please​
yaroslaw [1]

Answer:

x = 115° , y = 65° , z = 115°

Step-by-step explanation:

The figure is a parallelogram.

Consecutive angles are supplementary ( sum to 180° ) , then

x + 65° = 180 ( subtract 65° from both sides )

x = 115°

Opposite angles are congruent , then

y = 65°

z = x = 115°

The length of a rectangle is three less than twice the width. If the perimeter is 156cm, find it’s dimensions.
Monica [59]

Answer:

length = 47, width = 25

Step-by-step explanation:

L = 2W - 3

2L + 2W = 156

2( 2w -3) + 2W = 156

4w - 6 + 2W = 156

6W = 150

W = 25

L = 2(25) - 3

L = 47
