Answer:

N=4

Step-by-step explanation:

Simplifying

3 + 4n + n = 2n + 15

Combine like terms: 4n + n = 5n

3 + 5n = 2n + 15

Reorder the terms:

3 + 5n = 15 + 2n

Solving

3 + 5n = 15 + 2n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-2n' to each side of the equation.

3 + 5n + -2n = 15 + 2n + -2n

Combine like terms: 5n + -2n = 3n

3 + 3n = 15 + 2n + -2n

Combine like terms: 2n + -2n = 0

3 + 3n = 15 + 0

3 + 3n = 15

Add '-3' to each side of the equation.

3 + -3 + 3n = 15 + -3

Combine like terms: 3 + -3 = 0

0 + 3n = 15 + -3

3n = 15 + -3

Combine like terms: 15 + -3 = 12

3n = 12

Divide each side by '3'.

n = 4

Answer:

n = 4

Step-by-step explanation:

3 + 4n + n = 2n +15

3 + 5n = 2n + 15

5n - 2n = 15 - 3

3n = 12

n = 12 / 3

= <u>4</u>

⊙M≅⊙N and ZY=32.6. Identify ST rounded to the nearest tenth.

The measure of length ST will be 6.4 So option B is correct.

<h3>What is a circle?</h3>

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

Given; M≅N and ZY=32.6

Identify ST;

Radius of the circle r = 24

We know that from pythagoras theorem;

ZP^2 + PM^2 = ZM^2

Also, 2 ZP = ZY

So,

16.3^2 + PM^2 = 24^2

PM^2 = 310.7

PM = 17.6

Since, M≅N then PM = SN.

therefore, SN = 17.6

ST = 24 - 17.6 = 6.4

Hence, The measure of length ST will be 6.4 So option B is correct.

Jade spent ⅓ of her math homework time working on word problems. What fraction of an hour did she spend working on word problems

Tems11 [23]

Answer:

If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour

Step-by-step explanation:

Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).

1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.
