Answer:
2.5
Step-by-step explanation:
y=kx, k is constant of prop
Their distance differs by 15 miles for each hour of travel time. Thus, the travel time of interest is
.. (180 -144) miles/(15 miles/hour) = 2.4 hour
The red car's speed is 180 mi/(2.4 h) = 75 mi/h.
The blue car's speed is 144 mi/(2.4 h) = 60 mi/h.
Answer:
3.5
Step-by-step explanation:
5.99+0.65=6.64
6.64-3.14=3.5
None of them are correct.
You have to isolate the variable by dividing each side by factors that don't contain the variable.
And when you do so you get a closed point starting at positive 8 and an extending ray to positive infinity and a closed point at -15 with a ray extending to negative infinity on the number line so none of them are correct.
Answer:
100000
Step-by-step explanation:
Move the decimal point to the right as many places as there are zeros in the factor.
Move the decimal point one step to the right (10 has one zero). Move the decimal point two steps to the right (100 has two zeros).
there I hope this helps you
