This is a pythagorean triple --> 3-4-5
Although you notice it is doubled but with the same pattern --> 6-8-10
Thus, the hypotenuse is 10.

Answer:
54 -6m
Step-by-step explanation:
For values of m < 9, the argument of the absolute value function is less than 0. Then the expression evaluates to ...
-(6m -54) = 54 -6m
60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles
part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles
total is 180mi+140mi=320miles
Answer:
Step-by-step explanation:
a) Perimeter of a rectangle = 2 *(L +w)
b) w = L - 2
Answer: B
c) Perimeter = 96 inches
2* (l +w) = 96
2*( L + L - 2 ) = 96 {Combine like terms}
2 * (2L - 2) = 96 {use distributive law}
2*2L - 2*2 = 96
4L - 4 = 96 {Add 4 to both sides}
4L = 96 +4
4L = 100 {divide both sides by 4}
4L/4 = 100/4
L = 25 inches
d) w = L - 2
= 25 - 2
w = 23 inches
There are 78 cookies in box C, 26 cookies in box B and 10 cookies in box A.
let the number of cookies in first box be represented mathematically as B-16
the number of cookies in second box be represented as B
the number of cookies in third box be represented as 3B
Since there are 124 cookies we can make an equation such that it becomes
B-16 +B +3B =124
Solving for B, we have
5B -16 =124
5B =124 +16
5B =130
B=130/5
B=26
Therefore Box A contains B-16 =26-16 =10 cookies
Box C contains 3B =3 X 26=78 cookies
