Answer:
the frist one is 2 the second on is 3.5 and the third one is 3 and the last on is 2.9
Answer:
None.
Step-by-step explanation:
4(x-1)-x = 3(x+5)-11
4x-4-x=3x+15-11
we combine like terms.
4x-x-4=3x+14
3x-4=3x+14
we then isolate the variables.
3x-4=3x+14
+4 +4
3x=3x+18
-3x -3x
0≠18
No solutions
Square number actually means the product can be multiplied by the same number, for example
2 = 1x1
4 = 2x2
9= 3 x 3
so 9 can be square rooted so it's a square number
also 4x4 is 16 not 8 and 8x8 is 64 not 16 :)
Answer is -3/4
Start with putting parentheses on the given numbers for these variables
Remove parentheses(When there is a in front of an expression in parentheses, the expression remains the same)
Reduce the numbers with the greatest common factor(3)
Calculate the difference 1 -7/4
Alternative form: -0.75
Answer:
x = 1
Step-by-step explanation:
Given
8 - 5(x - 3) = 18 ( subtract 8 from both sides )
- 5(x - 3) = 10 ( divide both sides by - 5 )
x - 3 = - 2 ( add 3 to both sides )
x = 1
