Please show me how to solve this equation step by step! 1/25(20-t)=4/25t-3/5

rjkz [21]

Remark

Multiply both sides of the equation by 25. Then you have an equation that you have already done probably.

Step One

Multiply both sides of the equation by 25

1 * (20 - t) = 4t - (3/5) * 25 Every part of the equation must be multiplied by 25

(20 - t) = 4t - 75/5 3*25/5 = 75/5

20 - t = 4t - 15 Add t to both sides

20 - t + t =4t + t - 15 Combine like terms

20 = 5t - 15 Add 15 to both sides

20 + 15 = 5t - 15 + 15 Combine like terms

35 = 5t Divide by 5

35/5 = 5t/5 Switch sides

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point T (-6, -3)

Point K (2, 3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute [DF]: $d = \sqrt{(2+6)^2+(3+3)^2}$
Add: $d = \sqrt{(8)^2+(6)^2}$
Exponents: $d = \sqrt{64+36}$
Add: $d = \sqrt{100}$
Evaluate: $d = 10$

Write an equation of the line that passes through ( -4. – 1) and is perpendicular to the line y= 4/3x+6.

Gnom [1K]

Answer:

y = -3/4x -4

Step-by-step explanation:

y = -3/4x + b

-1 = -3/4(-4) + b

-1 = 12/4 + b

-1 = 3 + b

-4 = b

y = -3/4x -4
