If Nick starts with 20, we can just plug it into p/2 - 12 to get 10-12 or -2. This means Nick did not get 20 cards. Now we have answered both. Two-liner!
I am going to build one table for each equation and so you can choose which one is representative of your tables.
x y = (1/2)x + 24 y = (4/3)x - 36 y = 2x - 48 y = 6x + 12
-6 -6/2 + 24 = 21 4(-6)/3 - 36 = -44 2(-6)-48=-36 6(-6)+12=-24
0 0 + 24 = 24 0 - 36 = -36 0- 48 = -48 0 + 12 = 12
6 6/2 + 24 = 27 4(6)/3 - 36 = -28 2(6)-48=-36 6(6)+12=48
12 12/2+24=30 4(12)/3-36=-20 2(12)-48=-24 6(12)+12=84
So, you know how to build each table, just replace x with a number to obtain the corresponding value of y.
The answer is 11.1
Because -(-7.2)+3.9= 11.1
Answer:
The diameter is 9.252 :)
Step-by-step explanation:
From the given diameter, get the radius. The perimeter of a semicircle is half the perimeter of a circle, but we excluded the base. So, the perimeter now is:
2πr+2r
Put the value of radius in the formula and get the answer wich is 9.252!
PLEASE MARK BRAINLIEST!!!
7x-5y=21 when x=4 from the coordinate point of (4,y)
Next,
7x-5y=21
Substitute x with 4
7(4)-5y=21
28-5y=21
Add 5 to each side
28-5y+5y=21+5y
28=21+5y
Subtract 21 to each side
28-21=21+5y-21
7=5y
Divided 5 to each side
7/5=5y/5
y=7/5
Or
y=1 2/5
Check:
7x-5y=21
Substitute x with 4 and y with 7/5
7(4)-5(7/5)=21
28-7=21
21=21. As a result, (4,7/5) is your correct answer. Hope it help!
