You have to take out the "|"
8x-1 ≤ 2x+11
8x-2x ≤ 11+1
6x ≤ 12
X ≤ 12/6
X ≤ 2
So she walked during this time with <span>4 miles per hour (x*4)
during
the rest of the way (which is 0.7-x, as the whole way took her 42
minutes, so the rest is 0.7-x) she walked with 5 miles per hour - the
distance was (0..7-x)*5 m/h
the total distance was 3 miles, so if we sum the two distances, we will get 3 miles:
x*4+ (0.7-x)*5=3
let's remove the bracket:
4x+0.7*5-5x=3
</span>
<span>4x+3.5-5x=3
subtract 3.5 from both sides:
4x-5x=3-3.5
-x=-0.5
multiply both sides by (-1)
x=0.5:
so she walked for half an hour alone, that is for 30 minutes!</span>
Answer:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
Step-by-step explanation:
First calculate the value of the 3 shirts as follows:
$ 71.83 - $ 7.99 = $ 63.84.
$ 63.84.
The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:
x + y + z = 63.84, then for each shirt would be the following equations:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:
<em>z = 63.84 - 20 - 30 = $ 13.84</em>
