Answer:
-x/3+2=y
Step-by-step explanation:
m should be -1/3
mx+n=y
-x/3+n=y
(-9,5) should equalize the equation
3+n=5
n=2
SO -x/3+2=y
Box A : 8.25
Box B : 8.2
Box C : 8.225
Box D : 8.05
heaviest box is box A
Answer:
3.14×48^2= 7234.6
Step-by-step explanation:
to find the area of a circle the formula is A=3.14r^2.
Ur common factor is 3....because 3 goes into both 15 and 18 evenly
ur common multiple will be 90....because both numbers have multiples of 90....15 * 6 = 90 and 18 * 5 = 90
so ur answer is : 3 and 90
K so you have to set 2 equations like this
x meaning the amount of adults
and y meaning the amount of kids
x+y=11
13.5x+8.25y=111.75
Then use substitution method and you get
x=11-y from the first equation
plug that in to the second and you get
13.5(11-y)+8.25y=111.75
Solve for y in that equation by distributing and then combining like terms
148.5 - 13.5y + 8.25y = 111.75
148.5 - 5.25y = 111.75
Then, you need to subtract 148.5 from each side and cancel the negatives
5.25y=36.75
solve for y and you get
36.75/5.25 = 7
y=7
