When solving this equation for x, what would you do next?

Leviafan [203]

Answer: A. Distribute the 3 outside of the parathesis to everything inside the parenthesis

We use the order of operations, also known as PEMDAS.

Since there is a variable inside the parenthesis, we cannot add/subtract 4. This means the next step is to distribute.

After distributing, the equation looks like this and we can solve it from there:

4x + 12 = 30

Newton uses a credit card with a 18.6% APR, compounded monthly, to pay for a cruise totaling $1,920.96. He can pay $720 per mont

Tresset [83]

<span>To find out how much Newton would pay you take the cruise cost of $1920.96 and divide by $720 to find out it would take 3 months for Newton to pay off the balance at $720 per month. The cost of the cruise would be $1920.96 + ($1920.96-$720)*0.186+ ($1920-$1440)*0.186)</span>

I need some serious help with standard form, Im really confused . Here's a problem ,

OLEGan [10]

I can see that the equation given above is a linear equation since y and x are the only variable and the degree is one. The standard form of a linear equation is written as:

Ax + By = C

We write the given equation into standard form as follows:

<span>y - 2 = 2(x - 3)
</span><span>y - 2 = 2x - 6
y -2x = -6 +2
y - 2x = -4
2x - y = 4</span>

The radius of a circle is 11.7 in. Find the circumference \textit{to the nearest tenth}to the nearest tenth.

hjlf

Answer:

73.5

Step-by-step explanation:

circumference = 2πr , where r = radius

given radius = 11.7 so r = 11.7

C = 2πr

==> plug in r = 11.7

C = 2π(11.7)

==> multiply 2 and 11.7

C = 23.4π

==> multipl 23.4 and π

C = 73.5 ( rounded to the nearest tenth )
