<span>Simplifying 0.5s + 1 = 7 + 4.5s Reorder the terms: 1 + 0.5s = 7 + 4.5s Solving 1 + 0.5s = 7 + 4.5s Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-4.5s' to each side of the equation. 1 + 0.5s + -4.5s = 7 + 4.5s + -4.5s Combine like terms: 0.5s + -4.5s = -4s 1 + -4s = 7 + 4.5s + -4.5s Combine like terms: 4.5s + -4.5s = 0.0 1 + -4s = 7 + 0.0 1 + -4s = 7 Add '-1' to each side of the equation. 1 + -1 + -4s = 7 + -1 Combine like terms: 1 + -1 = 0 0 + -4s = 7 + -1 -4s = 7 + -1 Combine like terms: 7 + -1 = 6 -4s = 6 Divide each side by '-4'. s = -1.5 Simplifying s = -1.5

0.5s + 1 = 7 + 4.5s   Subtract 4.5s from both sides
  -4s + 1 = 7              Subtract 1 from both sides
       -4s = 6              Divide both sides by -4
          s = -\frac{6}{4}   Simplify
          s = -\frac{3}{2}

A sum of two mixed numbers is given.<br><br> What is the missing number?
kaheart [24]

Answer:

16.

Step-by-step explanation:

The whole numbers stay the same so it stays as 2. The way they get 30 for the denominator is by multiplying the fraction 1/3 by 10 and 1/5 by 6. So now we have 10/30 and 6/30. Add them together, 10+6=16

I NEED HELPPP<br><br> Whats the length of LN?
andre [41]

Answer:

LN = 66 cm

Step-by-step explanation:

The 3 parallel lines divide the 2 sides they intersect in proportion, that is

\frac{DE}{EF} = \frac{LM}{MN} , substitute values

\frac{7}{15} = \frac{LM}{45} ( cross- multiply )

15LM = 315 ( divide both sides by 15 )

LM = 21

Hence

LN = LM + MN =  21 + 45 = 66 cm
