In order to compare the distances, we have to change them into one type of unit,
so, 4 Km = 4,000 m
We know,4,000 > 700
In short, Jessica ran more than Kristy
Hope this helps!
Answer:

Step-by-step explanation:
move the decimal so there is one non-zero digit to the left of the decimal point. the number of decimal places you move will be the exponent on the 10. if the decimal is being moved to the right, the exponent will be negative. if the decimal is being moved to the left, the exponent will be positive.
Answer:x=−136
Step-by-step explanation: Step 1: Simplify both sides of the equation.
2+x=
7
8
x−15
2+x=
7
8
x+−15
x+2=
7
8
x−15
Step 2: Subtract 7/8x from both sides.
x+2−

8
x=

8
x+2=−15
Step 3: Subtract 2 from both sides.

x=−17
Step 4: Multiply both sides by 8.
8*(

x)=(8)*(−17)
Answer:
choice a.) degree 3, constant term -1 leading coefficient 1
Step-by-step explanation:
expand the binomial product
(x - 1)(xx + 1) = xxx - 1 + x - xx
The answer would be 32,200 50*28*23
