Answer:

x = teaspoon of soda needed = 2 teaspoons of baking soda for 1 teaspoon of salt

y = teaspoons of baking soda needed = 1/2 teaspoons of salt needed for 1 teaspoon of baking soda

Step-by-step explanation:

Teaspoon of salt : Teaspoon of soda

1/8 : 1/4

How much baking soda is needed for 1 teaspoon of salt?

Let

x = teaspoon of soda needed

Teaspoon of salt : Teaspoon of soda

1 : x

Equate both proportion

Teaspoon of salt : Teaspoon of soda

1/8 : 1/4 = 1 : x

1/8 ÷ 1/4 = 1/x

1/8 × 4/1 = 1/x

4/8 = 1/x

Cross product

4*x = 8*1

4x = 8

x = 8/4

= 2

x = 2 teaspoons of

x = teaspoon of soda needed = 2 teaspoons for 1 teaspoon of salt

2. How much salt is needed for 1 teaspoon of baking soda?

Let y = teaspoons of baking soda needed

Teaspoon of salt : Teaspoon of soda = y : 1

Equate the proportion

1/8 : 1/4 = y : 1

1/8 ÷ 1/4 = y / 1

1/8 × 4/1 = y / 1

4/8 = y / 1

Cross product

4 * 1 = 8 * y

4 = 8y

y = 4/8

= 1/2

y = 1/2 teaspoons of baking soda

y = teaspoons of baking soda needed = 1/2 teaspoons needed for 1 teaspoon of baking soda

Answer:

Credit card B is a better deal

Step-by-step explanation:

in order to compare both credit cards, we must either convert the APR into a monthly rate or the monthly rate to APR.

convert credit card A's APR to monthly rate:

= 22.45% / 12 ≈ 1.87%, which is higher than 1.25%, so credit card B is better

OR

convert credit card B's monthly rate to APR:

= 1.25% x 12 = 15%, which is lower than 22.45%, so credit card B is better

Pulling out like terms

4.1     Pull out like factors :

  6k3 + 10k2 - 56k  =   2k • (3k2 + 5k - 28)

Trying to factor by splitting the middle term

4.2     Factoring  3k2 + 5k - 28

The first term is,  3k2  its coefficient is  3 .

The middle term is,  +5k  its coefficient is  5 .

The last term, "the constant", is  -28

Step-1 : Multiply the coefficient of the first term by the constant   3 • -28 = -84

Step-2 : Find two factors of  -84  whose sum equals the coefficient of the middle term, which is   5 .

     -84    +    1    =    -83

     -42    +    2    =    -40

     -28    +    3    =    -25

     -21    +    4    =    -17

     -14    +    6    =    -8

     -12    +    7    =    -5

     -7    +    12    =    5    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -7  and  12

                    3k2 - 7k + 12k - 28

Step-4 : Add up the first 2 terms, pulling out like factors :

                   k • (3k-7)

             Add up the last 2 terms, pulling out common factors :

                   4 • (3k-7)

Step-5 : Add up the four terms of step 4 :

                   (k+4)  •  (3k-7)

            Which is the desired factorization

Final result :

 2k • (3k - 7) • (k + 4)

Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

The exterior angle is equal to the sum of the interior angles in a given triangle.

The measure of the other remote interior angle is 60°.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Let the measure of the other interior angle = M

The exterior angle is equal to the sum of the interior angles in a given triangle.

An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.

This means,

M + 20 = 80

Solve for M.

M + 20 = 80

Subtract 20 on both sides.

M = 80 - 20

M = 60

Thus,

The measure of the other remote interior angle is 60°.

Answer:

(1, 4 )

Step-by-step explanation:

Given the 2 equations

y = x + 3 → (1)

y = 4x → (2)

Substitute y = 4x into (1)

4x = x + 3 ( subtract x from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (2)

y = 4x = 4 × 1 = 4

Solution is (1, 4 )
