Answer:
matter is any substance that has mass and takes up space by having volume
Step-by-step explanation:
Answer: a burger is $5.25, fries are $1.50
b = burger, f = fries
3b + 3f = 20.25
5b + 8f = 38.25
First, solve for b in terms of f
3b = 20.25 - 3f
b = 6.75 -f
Then substitute that for b in the other equation to solve and get a numerical value for f.
5(6.75 -f) + 8f = 38.25
33.75 -5f +8f = 38.25
33.75 + 3f = 38.25
3f = 4.5
f = 1.5
Now substitute that in to get a numerical value for b
b = 6.75 - 1.5
b = 5.25
Checking the math:
3b + 3f = 20.25
3(5.25) + 3(1.5) = 15.75 + 4.5 = 20.25
We are given with the expression above such that the required in the problem is the quotient of the two polynomials. We just have to try each of the polynomials given as option to 3x2 + 2 to give the equation in the numerator. The answer is B.) 2x^2 – 5x – 2
Answer:Length and angle measure
Step-by-step explanation:
The length measure is the distance along the curve (arc) and the angle measure is the angle that the arc makes with the center of the circle.
