WARM UP Solve each equation.
LEARNING GOALS
• Use strategies to solve linear equations with variables on
both sides of the equals sign
• Solve linear equations with rational number coefficients.
• Combine like terms and use the Distributive Property to
solve linear equations.
1. 2.5x + 100 = 600
2. 10 = 2x - 4
X=7
3. 1x + 5 = 30
100

You have solved equations by combining like terms and using inverse operations. How can
you solve equations when there are variables on both sides of the equation?

answer: procent 54 wynosi 33,33%

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
