Answer:

x=14, y=37

Step-by-step explanation:

We know that (4y-10)° and 3x° are supplementary angles, meaning the total sum of the angles add up to 180°. (4y-10)° is also corresponding to the blank angle below (9x+12)°, making it a vertical angle. Since (4y-10)°=(9x+12)° because they are vertical angles, then that means we can solve for x:

Original Equation: (4y-10)°+3x°=180

New Equation: (9x+12)°+3x°=180

9x+12+3x=180

12x+12=180

12x=168

x=14

So x is 14

Because x=14, then y is:

4y-10+3(14)=180

4y-10+42=180

4y+32=180

4y=148

y=37

So y is 37

bogdanovich [222]

Answer:

6 teaspoons

Step-by-step explanation:

2 teaspoons = 1/3 tsp of salt

6 teaspoons = 1 tsp of salt

This was done by multiplying 2 by 3 since 3 thirds (3/3) make one whole.

So if 2 teaspoons are used for 1/3 teaspoon of salt, 4 teaspoons would be used for 2/3 teaspoon of salt and 6 teaspoons would be used for 1 teaspoon of salt.
