Answer:
AB=29; BC=27
Step-by-step explanation:
So they told us AB=4x+9 and that BC=5x+2, and AC=56 , now to help with the question you can draw this information on a number line. Now on a number you can see that basically AC=AB+BC.
So you would write it as such,,
4x+9+5x+2=56
Combine like terms
9x+11=56
Now you have to isolate the x by itself but first get rid of the 11.
9x+11-11=56-11
You would get
9x=45
Here you can divide 9 by both sides to isolate x.
9x/9=45/9
{x=5}
Now to find the value for both substitue x in the equations for both
1. AB=4x+9 where x is 5
4(5)+9 =AB
20+9 =AB
29=AB
You would do the same with BC
2. BC= 5x+2 where x is 5
5(5)+2= BC
25+2= BC
27=BC
If you want to check your answers you can just substitute x for 5 in the first equation we did where AC=AB+BC
Answer:
Brian's average speed: 14.73 mile/hour
The traveled distance by skiing he estimated: 11.0475 miles.
As the information provided in table, the time he spent for skiing is 0.75
=> The distance Brian traveled by skiing: 14.73 x 0.75 = 11.0475 (miles)
=> Brian's product is correct.
=> Rounding to the nearest whole number => 11.0475 = 11 (miles)
Rounding the Brian's average speed to the nearest whole number:
=> 14.73 = 15 mile/hour
Round the activity time to the nearest whole number:
=> T = 3 + 1.45 + 1.2 + 0.75 = 6.4 = 6 (hour)
Hope this helps!

Answer:
Step-by-step explanation:
A proportional constant satisfies
y/x=k, where k is the constant of proportion
Since
y/x=k
y=kx
You are given
y=1.5x so
k=1.5
Answer:
Step-by-step explanation:
1) length of the field = 18 unit= 18*20=360 ft
2) circumference = 2(l+w)
2*(18*20+8*20)=1040
3) Area of the field = 18*8 units = 18*20*8*20ft^2 = 57600ft^2
Cost for the entire area= 57600*2.69= 170,000$
No it doesn't
