Answer:

  B)  x = 4

Step-by-step explanation:

Perhaps angles A and D are adjacent, so have a sum of 180°.

  133° + (3x +35)° = 180°

  3x +168 = 180 . . . . . . . . simplify

  x + 56 = 60 . . . . . . . . . . divide by 3

  x = 4 . . . . . . . . . . . . . . . . subtract 56

Answer:

\large \boxed{\sf \ \ x=0, \ \ y=-5 \ \ }

Step-by-step explanation:

Hello, please consider the following.

We have two equations:

(1) -2x - 4y = 20

(2) -3x + 5y = -25

5*(1)+4*(2) gives

   -10x - 20y -12x + 20y = 100 - 100 = 0

   -22x = 0

   x = 0

I replace in (1)

   -4y = 20

   y = -20/4 = -5

There is one solution x = 0, y = -5

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Nathan hit 19 homeruns. He scored 3 fewer homeruns than twice the number of homeruns hit by jason. Write and solve an equation t
Vinvika [58]

Jason hit 11 homeruns.

Step-by-step explanation:

Homeruns hit by Nathan = 19

Let,

Homeruns hit by Nathan = x

Homerun hit by Jason = y

According to given statement;

x = 2y - 3   Eqn 1

We know that Nathan hit 19 homeruns, therefore, putting x=19 in Eqn 1

19=2y-3\\19+3=2y\\22=2y\\2y=22

Dividing both sides by 2;

\frac{2y}{2}=\frac{22}{2}\\y=11

Jason hit 11 homeruns.
