Gather like terms: 2m - m + 3 + 4 = m + 7.

3*(2m + 1) is equivalent.

If: 9m+2m = 33 Then: m = 3

1/m + 1/2m = 6 LCD is 2m (2 + 1) / 2m = 6 3/2m = 6 3/6 = 2m = 1/2 m = 1/4

Since 100 cm = one meter then 60 cm = 60/100 meter Th efraction in 2 meters is 60/100 divided by 2 or 60/200 = 6/20=3/10

Gather like terms: 2m - m + 3 + 4 = m + 7.

Remember there are 100 cm - 1 m Hence in 2m = 200 cm So 75cm / 200 cm = 75/200 Cancel down by '25' 3/8 The answer!"!!!!

11m + 6n - 2m + 9n = 9m + 15n or 3(3m + 5n)

If: 9m+2m = 33 Then: m = 3

3*(2m + 1) is equivalent.

1/m + 1/2m = 6 LCD is 2m (2 + 1) / 2m = 6 3/2m = 6 3/6 = 2m = 1/2 m = 1/4

Assuming you mean 2m2... (2m - 3)(m + 4)

4, 100, 2, 3

5m+3=3m+9 5m+3-3=3m+9-3 5m=3m+6 5m-3m=3m+6-3m 2m=6 (2m)/2=6/2 m=3

To calculate the number of moles of HCl, you need to use the formula: moles = Molarity (M) x Volume (L) Convert 230 cm^3 to liters: 230 cm^3 รท 1000 = 0.23 L Now, plug in the values: moles = 2M x 0.23 L = 0.46 moles of HCl in 230 cm^3 of 2M hydrochloric acid.
