HELPPP PLS I DON’T UNDERSTAND

Answer:

n = - [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

Given

- 5(n - 1) = 7(n + 3) ← distribute parenthesis on both sides

- 5n + 5 = 7n + 21 ( subtract 7n from both sides )

- 12n + 5 = 21 ( subtract 5 from both sides )

- 12n = 16 ( divide both sides by - 12 )

n = [tex]\frac{16}{-12}[/tex] = - [tex]\frac{4}{3}[/tex]

Answer:

Step-by-step explanation:

To solve this you have to use the distributive property.

So first you would distribute the -5 to n and -1.

So the new equation will be -5n + 1 = 7 (n + 3)

Next, distribute the 7 to n and 3.

The new equation will be -5n + 1 = 7n + 21

Next you simplify by adding 5n to both sides which will give you 1 = 12n + 21

Then you subtract 21 from both sides and get -20 = 12n

So then you divide both sides by 12 to get n by itself and you are left with  -5/3 = n

Answer:

20

Step-by-step explanation:

because angle 5 is found on the same line as 45 degrees (don't remember what that's called), we can subtract from 180 to find

angle 5 = 135

angle 5 and 5x+35 are alternate interior angles, so they have the same value

135=5x+35

100=5x

20=x

Answer:

120 grams of 20% sugar and 480 grams of 10% sugar

Step-by-step explanation:

The reason that the answer is what it is is because the total of the sugar syrup must be 600 grams. It is 12% which means that its 1/5 20% and 4/5 10% and if you divide 600 by 5 you get 120 therefore 120 grams of 20% sugar is correct and for the rest just subtract 120 from 600 the get the answer.

There are 120 g of 20% sugar syrup and 480 grams of 10% of sugar syrup.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

A 20% sugar syrup is mixed with 10% sugar syrup.

And, The result is 600 g of 12% sugar syrup.

Now,

It is 12% which means that its 1/5 of 20%.

Hence, Amount of sugar grams = 600 / 5

                                                  = 120 grams

And,  It is 12% which means that its 4/5 of 10%.

Hence, Amount of sugar grams = 600 / (4/5)

                                                  = 480 grams

Answer: Total work stations = 20

Step-by-step explanation:

Total clay = [tex]\dfrac58[/tex] pound

Clay at each work station =  [tex]\dfrac1{32}[/tex] pound

Total work stations = (Total clay ) ÷ (Clay at each work station )

[tex]=\dfrac58\div\dfrac{1}{32}\\\\=\dfrac58\times32\\\\= 5\times4\\\\= 20[/tex]

Answer:

Infinitely many solutions

Step-by-step explanation:

y = -1/6x + 5

x + 6y = 30

We can solve this system by using substitution or elimination. Since we are given an isolated y-value, I'll be using the substitution method.

Substitute y = -1/6x + 5 into the second equation for y.

Distribute 6 inside the parentheses.

Combine like terms.

Since this is a true statement, we can conclude that this system has a solution of all real numbers, or infinitely many solutions.

We can also see that these equations are indeed equivalent by multiplying the top equation by 6.

6 * (y = -1/6x + 5) → 6y = -x + 30

Adding x to both sides and rearranging terms gives us x + 6y = 30, which is the same as the second equation.

Answer:

Percent increase = 60%

Percent increase with baggage = 83%

Step-by-step explanation:

Given that:

Old price of the ticket = $210

New price of the ticket = $335

Increase amount =335-210 = $125

Percent increase = [tex]\frac{Inrease\ amount}{Old\ price}*100[/tex]

Percent increase = [tex]\frac{125}{210}*100 = 0.595*100[/tex]

Percent increase = 59.52% = 60%

Additional charges = $125+$50 = $175

Percent increase = [tex]\frac{175}{210}*100[/tex]

Percent increase = 83%

Hence,

Percent increase = 60%

Percent increase with baggage = 83%

Answer and Step-by-step explanation:

Trigonometric Function (These only work for right triangles):

SOH-CAH-TOA

S = Sine = sin

C = Cosine = cos

T = Tangent = tan

O = Opposite (side)

H = Hypotenuse (side)

A = Adjacent (side)

SOH = sin(angle) = [tex]\frac{opposite}{hypotenuse}[/tex]

CAH = cos(angle) = [tex]\frac{adjacent}{hypotenuse}[/tex]

TOA = tan(angle) = [tex]\frac{opposite}{adjacent}[/tex]

1. sinQ (Q is the angle) = [tex]\frac{14}{50} = \frac{7}{25} = 0.28[/tex]

Use Pythagorean Theorem to find side PQ.  [tex]14^{2} + PQ^{2}= 50^{2} \\PQ^{2} = 2304\\PQ = 48[/tex]

2. cosQ = [tex]\frac{48}{50} = \frac{24}{25} = 0.96[/tex]
