If we have a picture that is 3 inches wide and 5 inches long. What would the dimensions be if I want the picture to be 10in. Long?

Rewrite one side (or both) by combining like terms.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

2x – 1 + 3x = 0..........(A)

5x – 1 = 0................(B)

To get Equation B from A, we would rewrite one side (or both) by combining like terms

2x – 1 + 3x = 0

5x – 1 = 0

Answer:

35/2 or 17.5

Step-by-step explanation:

2x / 7 - 3 = 2

2x / 7 - 3 + 3 = 2 + 3

2x / 7 = 5

(2x /7) x 7 = 5 x 7

2x = 35

x = 35/2 or 17.5

Answer:

[tex]x = \frac{35}{2} [/tex]

Step-by-step explanation:

[tex] \frac{2x}{7} -3=2[/tex]

[tex] \frac{2x}{7} = 2 + 3[/tex]

[tex]\frac{2x}{7} = 5[/tex]

[tex]x = \frac{7}{2} \times 5[/tex]

[tex]x = \frac{35}{2} [/tex]

Decimal Form:

[tex]x = 17.5[/tex]

Mixed Number Form:

[tex]x = 17 \frac{1}{2} [/tex]

Answer:

x = 2

Step-by-step explanation:

[tex]\frac{x}{x+1} =\frac{2}{x+1}[/tex]

x ≠ 0

x ≠ - 2

x ≠ - 1

[tex]\frac{x}{x+1}(x+1) =\frac{2}{x+1}(x+1)[/tex]

x = 2

Answer:

in all cases x/100 is just a way to represent percentage. and since it's the same everywhere, it's not even relevant to decide wich option describes the context right

A) 80/140 is the portion that describes the book readers over all people surveyed

B) 31/63 just 63 people are relevant bc it's specified that we only consider beach travelers.

that also explains the 31, bc that's the number of beach travelers who'd like to watch a movie

C) 15/80 only 80 movie watchers in total, of whom 15 would prefer the city

Answer:

Answer:

Step-by-step explanation:

I'll just write log for log base 10.  The important rules about logarithms we need to know are:

[tex] a \log b = \log( b^a) [/tex]

[tex] \log a + \log b = \log( ab) [/tex]

and at the end we'll need something like

[tex]\log a = \log b \implies a=b[/tex]

Suitably armed we can begin,

[tex] \left( 1 + \dfrac{1}{2x} \right) \log 3 + \log 2 = \log (27 - 3^{1/x}) [/tex]

First rule,

[tex] \log 3^{ 1 + 1/2x}  + \log 2 = \log (27 - 3^{1/x}) [/tex]

Second rule,

[tex] \log 2(3^{ 1 + 1/2x})  = \log (27 - 3^{1/x}) [/tex]

Third rule,

[tex] 2(3^{ 1 + 1/2x})  = 27 - 3^{1/x} [/tex]

We can rewrite this to be a quadratic equation in [tex]y=3^{1/2x}[/tex].

[tex]  6 (3^{1/2x})  = 27 -  (3^{1/2x})^2 [/tex]

[tex]y^2 +6y - 27 =0[/tex]

[tex](y - 3)(y+9)=0[/tex]

[tex]y=3 \textrm{ or } y=-9[/tex]

First solution:

[tex]3^{1/2x} = 3 = 3^{1}[/tex]

[tex]1/2x = 1[/tex]

[tex]1=2x[/tex]

[tex]x = 1/2[/tex]

Second solution,

[tex]3^{1/2x} = -9[/tex]

No real powers of 3 will be negative, no solution here.

Answer: x=1/2

Check:  

1 + 1/2x = 2 so the left side is log 2(3²) = log 18

Right side, log(27-3^2) = log 18  √

Answer: A. Long-term capital gains are from investments that have been held for more than one year and are taxed at a lower rate than short-term capital gains.

Step-by-step explanation:

Long-term capital gains are indeed from investments that have been held for more than a year as opposed to short term gains from investments of less than a year. This means that long term gains can come from investments such as stocks and bonds.

Long-term capital gains are taxed at a lower rate than short term gains with most long term gains being taxed at 15% or lower. This is in contrast to short-term gains that are taxed at the same rate as ordinary income which means it could go up to as high as 37%.

Answer: A

Step-by-step explanation:

Answer:

455 square kilometers (km2)

Step-by-step explanation:

Step 1: Find the area of the white square: 11 km x 11 km= 121 km2

Step 2: Find the area of the green square: 24 km x 24 km= 576 km2

Step 3: Subtract the white square from the green square: 576-121= 455

Step 4: The answer is 455 square kilometers (km2). Hope this helped!

=======================================

Work Shown:

1 liter = 1000 mL

3 liters = 3000 mL

I multiplied both sides by 3.

Divide that result over 500 to get 3000/500 = 6

So she'll need to buy 6 cartons.

-------

You could also solve like this:

(1 carton)/(500 mL) = (x cartons)/(3000 mL)

1/500 = x/3000

1*3000 = 500*x ... cross multiply

3000 = 500x

500x = 3000

x = 3000/500 .... dividing both sides by 500

x = 6

Answer: chupa verga maricon de mierda

Step-by-step explanation:

Answer:

x = 51

Step-by-step explanation:

The two angles form a straight line

Angles that form a straight line add up to equal 180

Hence, 2x + 4 + x + 23 = 180

( note that we just created an equation that we can use to solve for x )

we now solve for x using the equation we created

2x + 4 + x + 23 = 180

step 1 combine like terms

2x + x = 3x

4 + 23 = 27

we now have 180 = 27 + 3x

step 2 subtract 27 from each side

180 - 27 = 153

27 - 27 cancels out

we now have 153 = 3x

step 3 divide each side by 3

153 / 3 = 51

3x / 3 = x

we're left with x = 51

Answer:

The perimeter of a rectangle has the general formula P=2L+2W. Since you know P and L, you can plug those values into the formula and solve for W.

Hope this answer is right!!

Answer:

Width: 13

Area: 42

Step-by-step explanation:

A rectangle has equal opposite sides, so if you know one side, you know that the opposite side will be the same. Then you can subtract it from the perimeter, and divide the remaining number in half because it represents the other opposite sides. If you were trying to find the area, do that to find the length and width. 29x13=42, so the area is 42. If you were trying to find the width, that would be 13 because

29+29=58

84-58=26

And 26/2=13

Answer:

10

Step-by-step explanation:

8 and 6 are the numbers you work with

using the formula [tex]a^{2} + b^{2} = c^{2}[/tex]

we get : [tex]8^{2}[/tex] + [tex]6^{2}[/tex] = [tex]c^{2}[/tex]

64 + 36 = [tex]c^{2}[/tex]

100 = [tex]c^{2}[/tex]

[tex]\sqrt{100} = \sqrt{c^{2} }[/tex]

10 = c

Answer:

Area of circle bounded by a 135 ° arc is 4.71 m ²

Step-by-step explanation:

Radius of circle, r = 2 m

Angle of the circle , θ = 135 °

Area of circle bounded by a 135 ° arc.

Using Formula

Area of circle = θ/ 360 × π × r ²

substitute the values,

Area of circle = 135 /360 × 3.14 × ( 2 m) ²

solve it

Area = 27 / 72 × 3.14 × 4 m ²

Area = 27 / 18 × 3.14

Area = 1.5 × 3.14

Area = 4.71 m ²

Therefore, Area of circle bounded by a 135 ° arc is 4.71 m ²

Answer: 2,396,558 Ringgit

Step-by-step explanation:

J = P * ( 1 + k)^n

P = initial investment of 1,000,000 Ringgit

k = rate of return of 6% per annum

n = Number of years of investment

J = 1,000,000 * ( 1 + 6%)¹⁵

= 1,000,000 * 2.396558193

= 2,396,558 Ringgit

Answer:

(-8,5)

Step-by-step explanation:

The standard form of the equation of a circle is expressed as;

(x-a)^2+(y-b)^2 = r^2 where;

(a, b) is the centre

r is the radius

Given the equation (x+8)^2+(y-5)^2=14.

Compare the two expressions

-a = +8

a = -8

Similarly;

-b = -5

b = 5

Hence the centre of the circle is at (-8,5)
