The fastest time is 57.50 and the slowest time is 58.49.
Step-by-step explanation:
We have y = 13 - 3x and y = 7 - x.
=> 13 - 3x = 7 - x
=> 2x = 6, x = 3.
Then y = 7 - (3), y = 4.
Hence the price of a pencil is $3 and the price of a notebook is $4. (C)
Step-by-step explanation:
Hey so ok, Ill explain this the best I can.
So you see the 10/2 (10/2 is the fraction just you cant type it in that way)
So 10/2 is litterally 10÷2, which is 5 just imagine that the line inbetween is a division symbol, and it goes from top to bottom, so for example 5/2 would be 5÷2... NOT 2÷5
With this said, to simplify 10/2, just divide the numerator, (Top) by the denominator (bottom) so --> 10÷2 = 5,
so Wednesday would equal 5 (and 5 is the same as 5/1 because 5÷1=5)
Do the same for Thursday 18÷3 = 6
So Thursday would equal 6 (and 6 is the same as 6/1 because 6÷1=6)
and since 6 > 5, (aka 6/1 > 5/1) She ran a longer distance per mile on Thursday, therefore she ran faster on Thursday.
Hopefully I answered your question in the right way.
Answer:
the length of ST = 3.6 to the nearest tenth
Step-by-step explanation:
Points on the Cartesian are written as (x, y)
Given points S(-4, -2) and T(-1, 0)
The distance between these two points is given by the formula
ST = √[(x₂-x₁)² + (y₂-y₁)²]
x₂ = -4
x₁ = -1
y₂ = -2
y₁ = 0
ST = √{[-4 - (-1)]² + [-2 - 0]²}
ST = √[(-4 + 1)² + (-2)²]
ST = √(-3²+4)
ST = √(9 + 4)
ST = √13
ST = 3.6 to the nearest tenth
