82/4+20-15
82:4=20.5
20.5+20=40.5
40.5-15=25.5
Distribute the negative sign to (7-5x) and then you will get -7+5x=-2x. Then you subtract 5x from both sides and you will get -7=-7x. Next you will divide by -7 to get x alone so the answer is x=1
The diameter of under the magnifying glasses is 6cm, so the actual size is 6÷5cm, the diameter is 1.2 cm

5 5/6 is bigger then 5 5/10
Answer:
x = 1
Step-by-step explanation:
(9x - 6) = 
(12 - 4x) ← distribute parenthesis on both sides
6x - 4 = 3 - x ( add x to both sides )
7x - 4 = 3 ( add 4 to both sides )
7x = 7 ( divide both sides by 7 )
x = 1
