The answer would be d=8t

This would be because the time they want is 1 hour. So when you plug in t as 1 you need d to equal 8. So you just have to change that 6 in the first equation to an 8. This new equation means that the person can travel 8 miles every hour.

**Answer:**

If I read this right

3 (n -12) + 14 = 4 (7 - 5n)

First, remove the parentheses

3 n - 36 + 14 = 28 - 20 n

Combining terms

23 n = 28 - 14 + 36 = 50

n = 50 / 23 = 2 4/23 = 2.17

**Answer:**

Yes . Divide by 10 for 10/20 to get 1/2.

10/10= 1

20/10= 2

10/20= 1/2

**Answer:**

Width of parking lot=72 feet

Length of parking lot=110 feet

**Step-by-step explanation:**

Step 1: Derive expressions for the length and width

width=x

length=y, but 34 feet less than twice the width=2 x-34

length=2x-34

Step 2: Derive expression for perimeter

Perimeter of a rectangle is given by;

P=2(L+W)

where;

P=perimeter of rectangle

L=length

W=width

in or case;

P=364 feet

L=2x-34

W=x

replacing;

2(2x-34+x)=364

4x-68+2x=364

4x+2x=364+68

6x=432

x=432/6

x=72

Width=x=72 feet

Length=2x-34=(2×72)-34=144-34=110 feet
