I need to know the dimensions to solve. Ex: "Line AC is 2.5 centimeters"
My bad - should've asked that under "Ask For Details."
Sorry :(
4.5(4-x) + 36 = 202 - 2.5(3x + 28)
Distributive property
18 - 4.5x + 36 = 202 - 7.5x - 70
Combine like terms
-4.5x + 54 = -7.5x + 132
Add 7.5x to both sides
3x = 78
Divide both sides by 3
x = 26
The second in the top row is this:
42.4-1.5(TIMES)3.1
42.4-46.5
-4.1
Answer:
y = 3x + 15
Step-by-step explanation:
1. Find the reciprocal of the slope and change signs: -3
2. y = 3x + b
3. Plug in x and y --> b = 15
4. Make your equation using y = mx + b: y = 3x + 15
X= -2/5 + y/5 solve for x by simplying both sides of the equation, then isolating the variable
