Answer: x+8=20

Step-by-step explanation:

Given

Equation is \frac{x}{2}+4=10

Mila uses the first step as multiplication to make the coefficient of x, 1

Mila maybe have multiplied the whole equation by 2 i.e.

\Rightarrow 2\left(\dfrac{x}{2}+4=10\right)\\\\\Rightarrow x+8=20

Y+9=-3(x-2) standard form
madam [21]

Hello!

"Standard form" looks like Ax + By = C.

Start by carrying out the indicated multiplication:

y + 9=-3(x-2) becomes y + 9 = -3x + 6

We want to group the x and y terms on the left and the constants on the right.  Achieve this by adding 3x to both sides, obtaining:  3x + y + 9 = 6.  Next, subtract 9 from both sides:  3x + y = -3.

The given equation, in standard form, is 3x + y = -3.

larisa [96]

Answer:

The price increases by 5439 dollars.

The price of the next model is 42439 dollars.

Step-by-step explanation:

The next model of sports car will cost 14.7% more so it will be 114.7% of the current model. Therefore you multiply

37000 * 1.147 = 42439

To find out how much it increases by, you find the difference between the two prices which is 5439 dollars.

Hope this helped!!

Evaluate the geometric series. Please help me out!!!
vredina [299]

Answer:

- 1364

Step-by-step explanation:

The n th term of a geometric series is

a_{n} = a(r)^{n-1}

where a is the first term and r the common ratio

4(-2)^{n-1} ← is an n th term

with a = 4 and r = - 2

The sum to n terms of a geometric series is

S_{n} = \frac{a(r^{n}-1) }{r-1}, thus

S_{10} = \frac{4((-2)^{10}-1) }{-2-1}

      = \frac{4(1024-1)}{-2-1}

      = \frac{4(1023)}{-3}

      = \frac{4092}{-3}

      = - 1364
