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
