Answer 1

Answer: 12)

5 x + 4 y = 10

4 y = 10 - 5 x

y = 10 - 5 x / 4
_______________________________

15)

14 = 7 y - 6 x

7 y = 14 + 6 x

y = 14 + 6x / 7
__________________________________

18)

3 + 6 x = 11 - 4 y

- 4 y = 11 - 3 + 6 x

- 4 y = 8 + 6 x

y = 1 / 4 ( 8 - 6 x )

hope this helps!

Answer 2

Answer: What you do is write down the original problem so you don't forget it then:
PROBLEM 12
5x+4y=10
Subtract 5x from each side which equals-
4y=10-5x which also equals 4y=-5x+10
Divide 4y by 4 as well as the other numbers
y=-5x/4+10/4
y=-5x/4+2 1/2

PROBLEM 15
14=7y-6x
Add -6x to each side
14+6x=7y
7y=6x+14
Divide 7y by 7 as well as the other numbers
y=6x/7+14/7
y=6x/7+2

PROBLEM 18
3+6x=11-4y
Subtract 3 from both sides
6x=8-4y
Subtract 8 from each side
6x-8=-4y
Divide -4y by -4 as well as the other numbers
6x/-4+-8/-4=y
6x/-4+2=y
y=6x/-4+2

There you go! Just ask if you have questions!

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
