Answer:

p = 1

Step-by-step explanation:

Given

3p - 6 + 7 = 32 - 4(2p + 5), that is

3p + 1 = 32 - 4(2p + 5) ← distribute and simplify right side

3p + 1 = 32 - 8p - 20

3p + 1 = 12 - 8p ( add 8p to both sides )

11p + 1 = 12 ( subtract 1 from both sides )

11p = 11 ( divide both sides by 11 )

p = 1

Answer:

y = -1/2x + 3.5

Step-by-step explanation:

The gradients of perpendicular lines multiply to make -1. The gradient of the line given is 2, so 2 multiplied by something gives us -1. 2 × -1/2 = -1. The gradient of the perpendicular line is -1/2

y = -1/2x + c

Now we can substitute x = 1 and y = 3 into the equation:

3 = -1/2(1) + c
3 = -1/2 + c
c = 3 + 1/2
c = 3 1/2 or 3.5 or 7/2

The equation of the line is y = -1/2x + 3.5

Hope this helps!

Darren wins a coupon for $4 off the lunch special for each of five days he pays $75 for his 5 lunch specials write and solve an

Valentin [98]

The original price for one lunch special is $19.

Explanation

The original price for one lunch special is 'p' dollar.

He wins a coupon for $4 off for each of five days. That means , he needs to pay $(p-4)$ dollar each day.

So, the total amount needed to pay for 5 days $= 5(p-4)$ dollar

Given that, he pays $75 for his 5 lunch specials. So the equation will be.....

$5(p-4)= 75\\ \\ 5p-20=75\\ \\ 5p= 75+20\\ \\ 5p= 95\\ \\ p=\frac{95}{5}=19$

So, the original price for one lunch special is $19.
