<h2>Answer:</h2>

Option: C is the correct answer.

          y=\dfrac{5x}{7}-\dfrac{10}{7}

<h2>Step-by-step explanation:</h2>

We are given a linear equation in terms of variable x and y as:

5x-7y=10

Now, we are asked to solve the equation for y i.e. we are asked to find the value of y in terms of the variable x.

Now, we add 7y on both the sides of the equation to get:

5x=10+7y\\\\i.e.\\\\10+7y=5x

Now, we subtract 10 from both the sides of the equation to get:

7y=5x-10

Now, we divide both side of the equation by 7 to get:

y=\dfrac{5x-10}{7}\\\\\\i.e.\\\\\\y=\dfrac{5x}{7}-\dfrac{10}{7}

5x-7y=10
-7y=10-5x
y=(10-5x)/-7
y=10/-7-5x/-7
y=5x/7-10/7
hence C is correct option

N the spring of 2008, petrol cost £1.029 per litre in london. on the same day, the exchange rate was $1 = £0.497. what was the p
Dmitriy789 [7]

1 liter of petrol in London costs £1.029

Since 1 gallon consist of 3.7854 liters, the cost of 3.7854 liters is calculated as:

Cost of 1 gallon of petrol in London = 3.7854*1.029 =£3.8951766

Next, we convert the pounds (£) to dollar($)

Since the exchange rate is 1$ =£ 0.497

£3.8951766 in $ = £3.8951766/£ 0.497 = 7.837$

The price of London petrol in dollars ($) per gallon =$7.84 (Rounded to nearest cents)

Answer:   1. ∠A= 80.75°  2. 41.79 cm^2

Step-by-step explanation:

Since, According to the sines low,

\frac{sin A}{CB} = \frac{sin C}{AB}

Here, CB= 4.1 cm,  AB = 3.3 and ∠ C = 52.6°

\frac{sin A}{4.1} = \frac{sin 52.6}{3.3}

⇒ sin A = 4.1\times\frac{sin 52.6}{3.3}

⇒  sin A =0.98699998308

⇒ A = 80.75°

2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1

=34.86 + 6.93

= 41.79 square cm

Please help! Thanks! (:

Ok this is simple. first, lets look at the 123 angle, so the entire line is 180. subtract 123 from 180 and you have 57. a triangle will always add up to 180 degress aswell. so add 58 and 57 and thats 115. so since a triangle will always add up to 180, subtract 115 from 180 and you have the missing angle:

Leonardo wrote an equation that has an infinite number of solutions. One of the terms in Leonardo's equation is missing, as show
Tanya [424]

Answer:

The missing term is 3x

Step-by-step explanation:

Given

-(x - 1) + 5 = 2(x + 3) - _

Required

Find _

For proper identification of the parameters, represent _ with Z

So, the equation becomes

-(x - 1) + 5 = 2(x + 3) - Z

Open bracket (start from the left hand side)

-x + 1 + 5 = 2(x + 3) - Z

-x + 1 + 5 = 2x + 6 - Z

Solve like terms

-x + 6 = 2x + 6 - Z

Subtract 6 from both sides

-x + 6 - 6 = 2x + 6 - 6 - Z

-x = 2x - Z

Subtract 2x from both sides

-x - 2x = 2x - 2x - Z

-3x = -Z

Multiply both sides by -1

-3x * -1 = -Z * -1

3x = Z

Reorder

Z = 3x

Hence, the missing term is 3x
