Answer:
1) 3
2) 1
3) -5
Step-by-step explanation:
The coefficients are the numbers that come before each variable.
The 3 in the first term is in front of the x^2; so the coefficient is 3.
There is no visible number in front of the y in the second term, but there is a y, so we can assume there's at least 1; so the coefficient is 1.
The term in front of x for the third term is -5, so the coefficient is -5.
Answer:
3 2/5
Step-by-step explanation:
8-3x4
ok well do 3x4 that is 12
so do 12 minus 8 which is 4. and 4 as a fraction is 2/5 so
do 6/2 plus 2/5
which is.....
.....
3 and 2/5
It would be the 1st one ( 12in× 1in/2.5ft) the reason is you want the measurements to match so that way when you solve the equation you are multiply 12 by 2.5 to get the number of inches
We know that the first cyclist has traveled 24.2 km at a speed of 10 km/h. Lets use the equation

to find the time of the first cyclist:


So, we know that she has traveled for 2.42 hours.
We also know that after she has traveled for 2.42 hours another<span> cyclist sets out in the same direction, so if </span>

represents the time of our first cyclist, <span>the time of our second cyclist will be </span>

.
Now we are going to use the equation

to relate the speeds and times of the two cyclist:
For the first one:

equation (1)
For the second one:

equation (2)
Replace (1) in (2)

The only thing left now is solve for

:




We can conclude that the second cyclist will catch up the first cyclist after
3.63 hours.
Just put it in a calculator!

25.09090909....
The answer is 25.09 repeating
Hope this helps!
