6b + 4r represents the total cost of the rice and beans gabriel bought. if he returns 2 bags of beans and 1 bag of rice, the expression that represents the total cost after the return is (6b + 4r) – (2b + r). what is this expression after simplifying?

Despite all the information you are given, all it is asking you to do is combine like terms. When there is a - outside the parentheses, you multiply everything inside of it by -1 (- represents a -1), so distribute the -1 to the terms:

6b + 4r - 2b - r

4b + 3r

As it is only asking for an expression, this is the final answer. Therefore, the expression that represents the total cost after the return is 4b + 3r.

Hope this helps! :)

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°
