[tex] \sf \sqrt{x + 3 = 12} [/tex]

[tex] \sf = \sqrt{x = 12 - 3} [/tex]

[tex] \sf = \sqrt{x = 9} [/tex]

[tex] \sf = \sqrt{9} [/tex]

[tex] \sf = \sqrt{3 \times 3} [/tex]

= 3

The solution of the linear equation [tex]\sqrt{x+3} = 12[/tex]  for the variable, x is 141.

Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.

Example = 2x +4 = 12

here, 4 and 12 are constants and x is variable

The solution of the equation can be calculated as:

[tex]\sqrt{x+3} = 12[/tex]

Squaring both side,

[tex]x+3 = (12)^2[/tex]

x+3 = 144

Subtract 3 from both the sides,

x = 141

The solution of the linear equation for the variable x is 141.

Answer:

x-intercept is (40/7, 0) and y-intercept is (0, 5)

Step-by-step explanation:

x-intercept ==> y-coordinate is 0 ==> y=0

y-intercept ==> x-coordinate is 0 ==> x=0

because the function is 7x + 8y = 40

when y = 0 ==> 7x = 40 ==> x = 40/7

so the x-intercept is (40/7, 0)

when x = 0 ==> 8y = 40 ==> y = 5

so the y-intercept is (0,5)

Answer:

x=r/2+y/2

Step-by-step explanation:

2x-y=r

you want x all by itself, move y first by adding y

2x = r + y

divide both r and y by 2 to leave x all by itself.

2x/2 = r/2 + y/2

2/2 = 1 so it's really 1x

x= r/2 + y/2

Answer:

The missing side would be 6.

And the area would be 54.

Step-by-step explanation:

The perimeter equals 30, that's the outside of the rectangle. They give you a part of the perimeter, 9ft. So 9ft and there's another 9ft on the bottom line, (because it is equal to the top width) Which equals 18. To get the other sides you need to subtract 18 from the whole perimeter, 30. Which gives you 12. And there's two sides left, so divide by 2, and you have 6 on each side(left and right sides) Perimeter is adding all the sides up.

And the Area formula is Area=Length times Width. Area=9ft×6ft Which equals 54.

Answer:

Discount = Original Price x Discount %/100

Discount = 395.49 × 30/100

Discount = 395.49 x 0.3

You save = £118.65

Final Price = Original Price - Discount

Final Price = 395.49 - 118.647

Final Price = £276.84. (ANSWER)

original price of washing machine is $564.99 if the sale price of the washing machine is $395.49 with 30% off.

Percentage is defined as a given part or amount in every hundred

Based on the given conditions, formulate:

x×(1-30%)=395.49

Apply multiplicative distribution

x-0.3x=395.49

Combine the like terms

0.7x=395.49

x=395.49/0.7

Convert decimal to fractions

x=(39549/100)/(7/10)

x=39549/(10×7)

x=39549/70

x=564.99

Hence original price of washing machine is $564.99

Answer:

3

Step-by-step explanation:

So first, plugin y to your equation, it should look like this: 4x+x+5+20. Now, we can solve this. Next, we have two x's so we can combine them. The equation will now look like this: 5x+5=20. Now, we have an extra 5 laying around that we need to get rid of, so we can subtract that 5 to both sides of the equation and we get this: 5x-5=20-5 which ends up being 5x=15. Now, we just divide both ides by 5 and since 15 divided by 5 is 3, we get: x=3
