we distribute then move placeholders to get
2x+4=4x-6+1
9=x
one solution
2. distribute
4x+12=3x+17
x=5
one solution
3. distribute and combine like terms
5x+4=5x-10+7
4=-3
false
no solution
4. distribute
2+10x=10x-5
2=-5
false
no solution
5. distribute
-18+15x=12x-18+3x
x=x
true

Answer:
I and II
Step-by-step explanation:
The inequality ...
3x +10 ≥ 2
has solutions ...
3x ≥ -8 . . . . . . . . subtract10
x ≥ -2 2/3 . . . . . divide by 3
Of the answer choices {-1, 3, -11}, the ones that are greater than -2 2/3 are ...
-1, 3 . . . . . . I and II only
Answer: 83.6
Step-by-step explanation:
The data shown below is: 81,83,84,85,85. The mean of this data set can be calculated via (81+83+84+85+85)/5=83.6
Hope it helps <3
P.S. brainliest brains?
If the base were 1, then the final value would never change...it would be a constant...
If the base is between zero and one, it is an exponential decay equation, so the final value would continually get smaller and smaller...
we know that
The fraction of each tile color can be found by dividing the number of tiles for each tile by the total number of tiles, then simplifying the fraction if possible.
Let
N----------> total number of tiles
Y---------> number of yellow tiles
B--------> number of blue tiles
P--------> number of purple tiles
we have

<u>1) Find the fraction of yellow tiles</u>
we know that
the fraction of yellow tiles is equal to

substitute the values

<u>2) Find the fraction of purple tiles</u>
we know that
the fraction of purple tiles is equal to

substitute the values

<u>3) Find the fraction of yellow tiles or purple tiles</u>
we know that
the fraction of yellow tiles or purple tiles is equal to

therefore
<u>the answer is</u>
