Answer:
x = 1/2
Step-by-step explanation:
2(4x+2) = 4x - 12(x-1)
Distribute
8x +4 = 4x - 12x +12
Combine like terms
8x + 4 = -8x +12
Add 8x to each side
8x+4+8x = -8x+12 +8x
16x+4 = 12
Subtract 4 from each side
16x +4-4 = 12-4
16x = 8
Divide by 16
16x/16 =8/16
x = 1/2
Answer:
y=7x+11 and y=6x=2
Step-by-step explanation:
Answer:
1. x=1
2. no solution
3. infinite solutions
Step-by-step explanation:
1. 2(x+3)=2x+5+x
2x+6=3x+5
6=x+5
1=x
2. 2(2x-3)=6x+2-2x-9
4x-6=6x+2-2x-9
4x-6=4x-7
-6=-7
-6 does not equal -7 so there is no solution
3. 4(2x+6)+2=2x+16+6x+10
8x+24+2=2x+16+6x+10
8x+26=8x+26
26=26
26 is equal to 26 so x could be equal to anything since it ends up cancelling itself out
steps I used to solve:
1. solve distributive property
2. combine like terms
3. add/subract from both sides to try and get x by itself
4. if x is by itself you have your answer, and if there isnt an x in the final answer there is no solution or infinite solutions.
This will be the same area as that inside a circle with a radius of 5
So....the area will be ≈ pi * 5^2 ≈ 25 pi units^2
