Solve the equation 2×-31=3(×+2)

Answers

Answer 1

Answer:

x=-37

Step-by-step explanation:

First, rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

2*x-31-(3*(x+2))=0

(2x - 31) - 3 • (x + 2) = 0

Pulling out like terms

3.1 Pull out like factors :

-x - 37 = -1 • (x + 37)

Equation at the end of step

-x - 37 = 0

Solving a Single Variable Equation:

4.1 Solve : -x-37 = 0

Add 37 to both sides of the equation :

-x = 37

Multiply both sides of the equation by (-1) : x = -37

Kim brought $39.75 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1 4 as much as the sketchbook, and the sketchbook cost 2 3 the cost of the paint set. Kim had $4.00 left over after buying these items

Answers

Answer:

I can't get past hre, equations are attached tho

Step-by-step explanation:

Equations:

[tex]b + s + p = 35.75[/tex]

[tex]\frac{1}{4} b = s[/tex]

[tex]\frac{2}{3} s = p[/tex]

Now I used Desmos to solve this, im sure theres a way to find it the legit way but i'm too lazy. Here's the image of what the graph is like:

brush =$20.21,. sketchbook =$6.21 , paint set=$9.32

Step-by-step explanation:

let the cost of the brush=x

the cost of the sketchbook=y

the cost of the paint set= z

total money used= $39.75-$4.00

=$35.75

x= 14+y

but y=2/3z

x= 14+2/3z

14+2/3z +2/3z +z =35.75

3×14 +3×2/3z+3×2/3z×3z=3×35.75

42 +2z +2z +3z =107.25

7z=107.25-42

7z=65.25

z=65.25/7

z=$9.32

y=$2/3×9.32

y=$6.21

x=14+y

x=14+6.21

x=$20.21

A dragon flew 300 miles from his castle to visit a friend. Flying with the wind, his trip took 2 hours. His return trip against the wind took 3 hours. What was the speed of the wind and the speed of the dragon in still air?

Please help me. I WILL mark brainliest and give lots of points.

Answers

Answer:I’m not sure about the wind but the speed of the dragon is 125mph

Step-by-step explanation:Remember,

Speed=Distance/Time

Distance=Speed x Time

Time=Distance/Speed

Knowing that the distance in both trips was the same, we can say that he flew his trip 150mph (Speed=300/2) the first time and 100mph (Speed=300/3) the second time. Next, we find the average of 150 and 100 and that is (100+150)/2 which is 125. I’m sorry I couldn’t find the speed of wind, but in my defense, I’m only in 6th grade. Hopefully that helped you, good luck!

Answer:

Speed of the wind was

25 miles per hour.

Speed of Mighty Dragon 125 was

miles per hour.

Find the area of the figure in the picture below

Answers

Answer:

183 cm^2

Step-by-step explanation:

the line through the shape line means that they are equivalent meaning the side that is empty not making the trapezoid would be 9 as well. moving the 3 over since it is right next to it. 3 times 9 equal 27cm^2. later we are gonna use this number to subtract

then make a different equation with 3+9 to the the full height of the trapezoid pretending it is not missing anything. 3+9=12

then use the formula to find the area of the trapezoid which is 1/2(h)(b1+b2)

add the 2 bases together to get 35. how did i get 35. 12+14=26 yes then include the 9 to get 35.

1/2(height=12)(35)=6(35)=210cm^2

then you used 210-27 to get 183cm^2

Soft drinks sell for P8.50 and fruit juice sells for P11.00 each. On a certain day, the number of soft drinks sold was four times the number of fruit juice sold. How many soft drinks were sold if the total income was P900.00?

Answers

The number of soft drinks sold was 4 times the number of fruit juice -> On average, every 4 soft drinks sold, 1 fruit juice is.

-> Every P34.00 of soft drinks sold, P11.00 of fruit juice is.

So, the income is P45.00 everytime.

Since the total income is P900.00, the amount of 4 soft drinks and 1 fruit juice sold is 900 : 45 = 20 times

So, there were 20 x 4 = 80 soft drinks sold.

Recheck : 80 x 8.5 + 20 x 11 = 680 + 220 = 900.

Find the missing angle.

Answers

Answer:

32 degrees

Step-by-step explanation:

The angle supplementary with the 122 degree angle measures 180-122=58 degrees.

So, the triangle has interior angles of f, 90, and 58 degres.

Since the angles in a triangle add to 180 degrees, f+180-90-58=32 degrees

Solve the equation in degrees for all exact solutions where appropriate. Round approximate answers in degrees to the nearest tenth. Write answers using the least possible nonnegative angle measures.

Answers

The equation is an illustration of trigonometry ratios, and the non-negative values of x are 30 and 270 degrees

How to solve the equation?

The equation is given as:

2sin²(x) + sin(x) = 1

Let y = sin(x)

So, the equation becomes

2y² + y = 1

Rewrite as:

2y² + y - 1 = 0

Expand

2y² + 2y - y - 1 = 0

Factorize

2y(y + 1) - 1(y + 1) = 0

Expand

(2y - 1)(y + 1) = 0

Split

2y - 1 = 0 or y + 1 = 0

Solve for y

y = 0.5 or y = -1

Recall that: y = sin(x)

So, we have:

sin(x) = 0.5 and sin(x) = -1

Take the arcsin of both sides

x = sin⁻¹(0.5) and x = sin⁻¹(-1)

x = 30 degrees and x = 270

Hence, the non-negative values of x are 30 and 270 degrees
