What is the answer to 4(x + -7) +12=20

Answers

Answer 1

Answer:     4(x - 7) + 12 = 20
4(x) - 4(7) + 12 = 20
   4x - 28 + 12 = 20
   4x - 16 = 20
   + 16 + 16
   4x = 36
      4 4
   x = 9

Answer 2

Answer: X=9You ise the distribution property and get 4x-28+12=20. Combine the like terms amd you get 4x -16=20. Add 166 to both sides and you get 4x =36. Divide by four and you get x=9

The Pool Fun Company has learned that, by pricing a newly released Fun Noodle at $4, sales will reach 8000 Fun Noodles per day during the summer. Raising the price to $5 will cause the sales to fall to 6000 Fun Noodles per day. Assume that the relationship between sales price, x, and number of Fun Noodles sold, y, is linear. Write an equation in slope-intercept form describing this relationship. Use ordered pairs of the form (sales price, number sold).

Answer: PART A:

The generic equation of the line is:

y-yo = m (x-xo)

First we look for the slope of the line:

m = (y2-y1) / (x2-x1)

m = ((5000) - (6000)) / (4-3)

m = -1000

Then, we substitute any point in the generic equation:

(xo, yo) = (4, 5000)

Substituting:

y-5000 = (- 1000) (x-4)

Rewriting:

y = -1000x + 4000 + 5000

y = -1000x + 9000

The equation is:

y = -1000x + 9000

PART B:

For the price of 3.50 we have:

y = -1000 * (3.5) +9000

y = 5500

Step-by-step explanation:

a pair of shoes is on sale for 30% off. the original price is p. which expression can be used to find the price of the shoes after the discount?

Answers

Original price = p
Discount price = p * (30/100)
= 0.3p
Price after the discount
p - 0.3p
0.7p

Answer:

Discounted price= 0.7 p

Step-by-step explanation:

Original price = p

Since we are given that 30 % is off on the price

So, 30 % of p

$(30)/(100) * p$

$0.3p$

So, the discount is of amount 0.3p

So, the discounted price = Original price - Discount amount

So,the discounted price = p-0.3p

Discounted price= 0.7 p

Hence expression can be used to find the price of the shoes after the discount is 0.7p
