0.1d+0.25(d+7)=5.25

0.1 d + 0.25 (d + 7) = 5.25

d = 10

Solution steps

0.1 d + 0.25 (d + 7) = 5.25

Multiply both sides by

100

10 d + 25 (d + 7) = 525

Expand

25 (d + 7) : 25 d + 175

10 d + 25 d + 175 = 525

Add similar elements:

10 d + 25 d = 35 d

35 d + 175 = 525

Move

175

to the right side

35 d = 350

Divide both sides by

35

d = 10

108 = - 8 x - 20

\frac{3 x}{4} - 5 = - \frac{7}{2}

h = v t - g t^{2}, v

- \frac{1}{3} x = 9

6 - 2 x = 8
