No Solution.

Once you combine the like terms 4n-2n of the second equation you end up with

2n+4 = 2n+1.

There is no value of n that results in a true equation.

Answer:

0 solutions

Step-by-step explanation:

2n + 4 = 4n + 1 - 2n

↑

first combine like terms (right side)

2n + 4 = 2n + 1

but this part you can tell that there's 0 solutions, because both sides have 2n/ same variable with same number.

Find all the missing elements : C=120degrees b= 5 c=11

mezya [45]

Answer:

A = 36.8°

B = 23.2°

a = 7.6

Step-by-step explanation:

Given:

C = 120°

b = 5

c = 11

Required:

Find A, B, and a.

Solution:

✔️To find B, apply the Law of Sines

$\frac{sin(B)}{b} = \frac{sin(C)}{c}$

Plug in the values

$\frac{sin(B)}{5} = \frac{sin(120)}{11}$

Cross multiply

Sin(B)*11 = sin(120)*5

Divide both sides by 11

$sin(B) = \frac{sin(120)*5}{11}$

Sin(B) = 0.3936

B = $sin^{-1}(0.3936)$

B = 23.1786882° ≈ 23.2° (nearest tenth)

✔️Find A:

A = 180° - (B + C) (sum of triangle)

A = 180° - (23.2° + 120°)

A = 36.8°

✔️To find a, apply the Law of sines:

$\frac{sin(A)}{a} = \frac{sin(B)}{b}$

Plug in the values

$\frac{sin(36.8)}{a} = \frac{sin(23.2)}{5}$

Cross multiply

a*sin(23.2) = 5*sin(36.8)

Divide both sides by sin(23.2)

$a = \frac{5*sin(36.8)}{sin(23.2)$

a = 7.60294329 ≈ 7.6 (nearest tenth)

Help!!

klio [65]

Answer:

The answer is 14.

Step-by-step explanation:

Since all of the angles of a triangle add up to be 180, then all you have to do is add the 2 angles together that you have and subtract that number from 180. For example 141+25=166, so, 180-166=14. 14 would be the measure of the third angle.

Pls help me!! Which two equations are equivalent? y= 1/2x+3 y=x+6 2y=x+6

Zigmanuir [339]

Answer:

first and third

Step-by-step explanation:

Consider

y = $\frac{1}{2}$ x + 3 ( multiply through by 2 )

2y = x + 6 ← third equation

You're at a clothing store that dyes your clothes while you wait. You get to pick from 4 pieces of clothing

Zielflug [23.3K]

1 / 12 is the probability that you'll end up with an orange hat.

Step-by-step explanation:

Given that,

There are 4 piece of clothing ⇒ shirt, pants, socks, or hat
There are 3 possible colors ⇒ purple, blue, or orange

To find the total number of outcome :

Total outcomes ⇒ (number of clothes) × (number of colors)

⇒ 4 × 3 = 12

Therefore, there will be 12 different possibilities.

The 12 different outcomes are :

⇒ Purple shirt, blue shirt, orange shirt

⇒ Purple pants, blue pants, orange pants

⇒ Purple socks, blue socks, orange socks

⇒ Purple hat, blue hat, and orange hat.

Now, the probability that you'll end up with an orange hat if you choose on random of 12 possibilities ⇒ No.of orange hats / Total no.of outcomes.

∴ P(orange hat) = 1 / 12
