With or without tiles simplify and solve each equation below for x. record your work. a.3x-7=2

x=3

Step-by-step explanation:

Addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

3x-7=2

add 7 both sides of an equation.

3x-7+7=2+7

simplify.

3x=9

divide by 3 both sides of an equation.

3x/3=9/3

simplify.

9/3=3

3*3=9

9/3=3

x=3 and 3=x

Hope this helps!

Thanks!

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
