The total cost of rice and beans bought by Gabriel is 6b + 4r.
The simplified expression of the final cost is 4b + 3r.
<h3>What is simplification?</h3>
Simplification can be defined as a process of replacing a mathematical expression by the cancellation of common factors, regrouping of terms in the same variable to get the more simple form of the given expression.
Given that
6b + 4r represents the total cost of the rice and beans Gabriel bought.
He returns 2 bags of beans and 1 bag of rice.
This can be written as,

Then, the total number of bags of rice and beans is given as,

When we simplify the above equation, we get,

Hence we can conclude that the expression for rice and beans after the return is (4b+3r).

Answer:
y-axis
Step-by-step explanation:
Theta = 10
2cos(30) = sqrt(3)
Theta = -10
2cos(-30) = sqrt(3)
Theta = 180 - 10 = 170
2cos(3×170) = -sqrt(3)
<span>The hundredth place is the one with two places to the right of the decimal place. For example in the number 123.4579, five is in the hundredths place.
Therefore, the answer 3.88 + 4.82 + 1.73 correctly shows rounding to the hundredths place. All of the numbers being added together only have two numbers after the decimal. By laws of math, when they are all added together, there will only be two number after the decimal.</span>
Answer:
zeros: x = -3, 3
Step-by-step explanation:
The zeros are the x values where the graph intersects the x-axis. to find the roots, replace the y with 0 and solve for x.
