Answers and Step-by-step explanations:

Let's look at the first row:

cost = _______ + _______ * (monthly payment)

The first blank should be the "down payment" because this is the initial, constant value that is paid. The second blank should be the "number of months" because this way, when multiplied by the actual amount each payment is (monthly payment), then we get the total amount paid during those months.

So, we have:

cost = (down payment) + (number of months) * (monthly payment)

Now for the second row, we just plug in numbers and variables:

335 = 50 + 6 * p

Finally, we can solve for p:

335 = 50 + 6p

6p = 285

p = $47.50

Answer:

Cost = down payment + no. of monthly payments × monthly payment

335 = 50 + 6 × p

285 = 6p

Find the value of y for which line a is parallel to line b

Vsevolod [243]

As is shown in the figure attached:

1. "A" and 76º are congruents, because they are Alternate Interior angles, so A=76º.

2. "D" and "x" are congruents, because they are Alternate Interior angles, so x=38º.

3. "A", "B" and "C" form a the triangle ABC. Then, we remember sum of the interior angles of a triangle is 180º, so we have:

76º+38º+B=180º
B=180º-76º-38º
B=66º

4. By definition, an exterior angle of a triangle is equal to the sum of the opposite interior angles to it. So, we can calculate the exterior angle "y" of the triangle ABC, as follows:

The opposite angles are: 76º and 66ª. Then, we obtain:

y=76º+66º
y=142º

Therefore, the answer is: The value of y is 142º.
