Answer:

x=4 y=3

Step-by-step explanation:

rewrite the equations- y=x-1 2x-3y=-1

solve y=x-1 for y

y=x-1

sub for x-1 for y in 2x-3y=-1

2x-3y=-1

2x-3(x-1)=-1

-x+3=-1

-x+3+-3=-1+-3

-x=-4

divide both sides by -4

x=4

sub 4 for x in y=x-1

y=x-1

y=4-1

y=3

In triangle abc, the measure of angle b is 32 degrees more than three times the measure of angle

Yuki888 [10]

Define x:
Let angle a be x.
angle a = x
angle b = 3x + 32
angle c = x + 58

Find x:
Angles in a triangle add up to 180°:
x + 3x + 32 + x + 58 = 180

Combine like terms:
5x + 90 = 180

Take away 90 from both sides:
5x = 90

Divide by 5 on both sides:
x = 18°

Find the angles:
angle a = x = 18°
angle b = 3x + 32 = 3(18) + 32 = 86°
angle c = x + 58 = 18 + 58 = 76°

Answer: The angles are 18°, 86° and 76°.

Consider the following equation.

Mice21 [21]

GIVEN EQUATION :-

x + 6 y = 9  ••• (i)

We have to find missing coordinate in ordered pair (2,?).

From ordered pair , we can observe that value of x is 2.

Putting value of x in equation (i).

2 + 6 y = 9

=> 6y = 9 -2

=> 6y = 7

=> y = 6/7

=> y = 0.8571428571

=> y = 0.86 (approx )

Now , ordered pair is ( 2, 0.86)
