Help Which statement is true about the expression 12 minus 7 + 3?
The expression is equivalent to 12 minus (7 + 3) because of the associative property.
The expression is equivalent to 12 + 3 + (negative 7) because of the associative property.
The expression is equivalent to 12 minus 3 + 7 because of the commutative property.
The expression is equivalent to 12 + 3 + (negative 7) because of the commutative property.

Step-by-step explanation:

12-7+3

Statement number 3 looks good to me im not sure but to me it looks good.

12-3+7~I don't think the answer would change...

Hope this helps pls give brainliest if u could Tysm if u do!

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
