The three sides of a triangle are n, 3n+3, and 2n+11. If the perimeter of the triangle is 50 inches, what is the length of each

mylen [45]

Answer:

6, 21, and 23 inches

Step-by-step explanation:

The perimeter of a triangle is equal to the sum of all side lengths in that triangle. We're given the perimeter as 50 inches, and the side lengths as n, 3n + 3, and 2n + 11.

This means that we can algebraically solve the equation $n + 3n + 3 + 2n + 11 = 50$

Step 1: Combine like terms.

$(n+3n+2n) + (3+11) = 50$
$6n + 14 = 50$

Step 2: Subtract 14 from both sides.

$6n + 14 - 14 = 50 - 14$
$6n = 36$

Step 3: Divide both sides by 6.

$6n/6 = 36/6$
$n = 6$

Step 4: Plug in the value of n as 6 in each side.

$(6) + (3(6) + 3) + (2(6)+11) = 50$
$(6) + (18+3) + (12+11) = 50$
$(6) + (21) + (23) = 50$

Therefore, the side lengths are 6, 21, and 23 inches.

Write out steps on how to solve 21.4divided by 4.75

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

21.4÷4.75

First- you have to move the decimal placement two times to the right
Second- you have to put the number 21.4 under the dividing box
Third- put the number 4.75 out to the left of the decimal box
Fourth- when that's all completed you have to multiply the 475. until you get clos to the number 2140.
Fifth- once done you have to subtract the multiplied number that you get you then subtract it from 2140
Sixth- you keep on doing the fifth step until you get a reasonable answer
Seventh- you write the answer down
Eighth- there is no eighth step so you can stop reading this answer
