Answer:
x = - 0.2
Step-by-step explanation:
4x+4= -0.3x+3
4x + 0.3x +4= 3 Add 0.3x to both sides
4.3x + 4 = 3 Simplify
4.3x = 3 - 4 Subtract 4 from both sides
4.3x = -1 Simplify
4.3x = -1 Divide by 4.3 to isolate the variable
x = - 0.2

Answer:
z = - 24
Step-by-step explanation:
Given
- 0.4(0.5z + 4) = 3.2 ( divide both sides by the multiplier - 0.4 )
0.5z + 4 = - 8 ( subtract 4 from both sides )
0.5z = - 12 ( divide both sides by 0.5 )
z = - 24
Answer:
160 and 161
Step-by-step explanation:
x is the first page and x + 1 is the second page
combine them and you get 2x + 1
2x +1 = 321
this simplifies to
2x = 320
divide by 2
320 = 160
