Landon used a semicircle, a rectangle, and a right triangle, to form a figure below. which is the best estimate of he area of the figure in square centimeters?

answer:

x = 3 ,   y = 1   (see attachment)

step-by-step explanation:

solve the following system:

{y = 4 - x

{y = x - 2

hint: | perform a substitution.

substitute y = 4 - x into the second equation:

{y = 4 - x

{4 - x = x - 2

hint: | choose an equation and a variable to solve for.

in the second equation, look to solve for x:

{y = 4 - x

{4 - x = x - 2

hint: | isolate x to the left hand side.

subtract x + 4 from both sides:

{y = 4 - x

{-2 x = -6

hint: | solve for x.

divide both sides by -2:

{y = 4 - x

{x = 3

hint: | perform a back substitution.

substitute x = 3 into the first equation:

{y = 1

{x = 3

hint: | sort results.

answer: {x = 3 ,   y = 1

answer:

the necklace consists of more green beads, with only two white beads in the entirety of the necklace.

step-by-step explanation:

step 1: in order to determine which color of beads had the greater amount, we must change the fractions to have the same denominator in order to properly compare the fractions.

2/6 x 5 = 10/30

3/5 x 6 = 18/30

step 2: now that we have found that there are 10 blue beads and 18 green beads, we must find out how many white beads there are by adding the fractions together to find the remaining number of beads.

10/30 + 18/30 = 28/30

step 3: finally, we must subtract the numerator and the denominator to find how many beads are remaining.

30 - 28 = 2

i hope this ! let me know if it did! : )

answer: 22 1/2

step-by-step explanation: first convert 4 1/2 into a mixed # = 9/2

the divide that by 5 (mult by reciprocal)

reciprocal is the # flipped so,

9/2 x 1/5

= 45/2

divide 45 by 2

answer:

5/6

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative
