VARVARA [1.3K]

Answer:

x=5

Step-by-step explanation:

Alright you will need to use PEMDAS for this

Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction ( Take note of this )

Step 1

9(3x – 16) + 15 = 6x – 24 You will remove parenthesis here

27x-129=6x-24

Step 2

Then subtract 6x,

27x-129=6x-24

21x-129=-24

Step 3

Then you add 129 to the sides,

21x-129=-24

21x=105

After that, you divide the sides by 21 so that you can get your answer

5

So therefore, your answer will be x=5

HIII PLS HELP <br>PLS SHOW ME ALL UR WORKINGS THXX

vladimir1956 [14]

Answer:

Step-by-step explanation:

(i) y = 3x

m = 3

Slope of the line perpendicular to line (y = 3x) = -1/m = -1/3

Equation of the line through origin : y = mx

$y = \frac{-1}{3}x$

(ii) Form of the equation of all lines which are perpendicular to y = 3x is

$y = \frac{-1}{3}x +c$

c is y-intercept

What is cos 30?<br>this is geometry

nirvana33 [79]

So the definition of the cosine of an angle of a right triangle is $\frac{adjacent}{hypotenuse}$ . You may remember this by SohCahToa (sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, tangent is opposite over adjacent).

Remember, adjacent refers to the side next to the angle in question, and the side can't also be the hypotenuse. The hypotenuse is that longest side and is opposite the right angle.

We have the cosine of 30°. We write

$\cos(30)= \frac{adj}{hyp} = \frac{ \sqrt{3}}{2}$

If one centimeter on the map above equals 30 miles, our vehicle gets 15 miles per gallon of gasoline, and gasoline costs $ 4.09

malfutka [58]

Answer:

$\large \boxed{\$98.16}$

Step-by-step explanation:

Assume that your map looks like the one below.

1. Calculate the distance

It looks like the distance on the map is 12 cm.

$\text{Distance} = \text{12 cm} \times \dfrac{\text{30 mi}}{\text{1 cm}} = \text{ 360 mi}$

2. Calculate the volume of gasoline

$\text{Volume} = \text{ 360 mi} \times \dfrac{\text{1 gal}}{\text{15 mi}} = \text{24 gal}$

3. Calculate the cost of the gasoline

$\text{Cost} = \text{24 gal} \times \dfrac{\$4.09}{\text{1 gal}} = \mathbf{\$98.16}\\\\\text{It will cost $\large \boxed{\mathbf{\$98.16}}$ to drive to the ski lodge.}$
