What is PEMDAS
What is the base and exponent of -95
base 9 exponent 5
3x+9=3x+9
Identity
x=yz solve for z
x/y = z
Solve |x-3|=9
x=-6 and x=12
Solve 5 X 4-3+2
19
what is the difference between -92 and (-9)2
-92 = -81 and (-9)2 = 81
10x+7=10x+4
Contradiction
zt+3=y solve for t
t= y-3/z
Solve 5<2x+4<36
1/2<x<16
Solve 8-22+(7-10)
1
Is this true |6-9| = |6| - |9| (correct it if it is wrong)
No! It should be |6-9| = |9| - |6|
3x+9=47
Conditional
7b+k-9=x solve for b
b= (x+9-k)/7
Solve |4x+7|=|3x+2|
x=-5 and x=-9/7
Solve 10-(-11 X 3)+(6-4)3
51
Is this true |9x5| = |9| x |5|
True
4(2x+9) = 8x+17
Contradiction; No solution
