I am not so sure but i think this might work.

Write an algebraic equation for “8 more than x is equal to 17 .” Write an algebraic inequality for “one-fifth of x is greater than x minus .” Write an algebraic inequality for “5 added to the quotient of a number and 3 is less than or equal to 7 times the sum of the number and 2.” For the number, use the variable.

X+8

An expression means that there is no equals sign, and the sum of two numbers means addition. When you don't know what the number is, use a variable. A variable is an unknown number, and represents that it is an unknown number. "x" is the most common variable used.

x+8 means that you are adding an unknown number and 8 together.

Answer:

553/900

Step-by-step explanation:

x = 0.6144444........

Multiply both sides by 1000

1000x = 614.444.....

Multiply both sides by 100

100x = 61.444.....

Now subtract,

1000x = 614.444....

100x = 61.444.....

900x = 553

x = 553/900

Answer:

1) 2 hours

2) 96 miles

Step-by-step explanation:

1) Eliot and William went hiking. They went at the same speed. Let x mph be their speed.

Elliot:

Distance = 8 miles

Speed = x mph

Time $=\dfrac{8}{x}$ hours

William:

Distance = 12 miles

Speed = x mph

Time $=\dfrac{12}{x}$ hours

It took Eliot $40\ min=\dfrac{40}{60}\ hour=\dfrac{2}{3}\ hour$ less than William, then

$\dfrac{8}{x}+\dfrac{2}{3}=\dfrac{12}{x}\\ \\\dfrac{2}{3}=\dfrac{12}{x}-\dfrac{8}{x}\\ \\\dfrac{2}{3}=\dfrac{4}{x}\\ \\2x=3\cdot 4\ \ [\text{Cross multiply}]\\ \\2x=12\\ \\x=6\ mph$
