Two-step equations with decimals and fractions<br><br> Solve for p.<br><br> −5(p+ 3/5 )=−4
GrogVix [38]

Answer:

1/5 or 0.2

Step-by-step explanation:

-5(p+3/5)=-4

Let's convert 3/5 to decimal form:

-5(p+0.6)=-4

Expand parentheses:

-5p-3=-4

Add -3 to both sides:

-5p=-1

Divide both sides by -5:

p=1/5 or 0.2

Hope this helps!

If the sum of six consecutive even integers is 306, what is the smallest of the six integers
Neko [114]

306/6 is 51 is you add one to one side and take away the other the six numbers become: 46, 48, 50, 52, 54, 56 as you added one to one side substituting the other you took away from, therefore the smallest would be 46.

Find the domain and range of radical function
Tju [1.3M]

The radical function is 3√x + 1.

Since the cubic root of zero is zero, 0 would be x.

Add zero and one, which gives you 1. 1 is y.

You get (0,1)

Since this is a positive radical, it would be going to the top right.

So, the domain is x ≥ 0

the range is y ≥ 1

The law of cosines is used to find the measure of Z.
Shtirlitz [24]

Answer:

C. Z=51^{\circ}

Step-by-step explanation:

We have been given a triangle. We are asked to find the measure of angle Z using Law of cosines.

Law of cosines: c^2=a^2+b^2-2ab\cdot \text{cos}(C), where, a, b and c are sides opposite to angles A, B and C respectively.

Upon substituting our given values in law of cosines, we will get:

16^2=19^2+18^2-2(19)(18)\cdot \text{cos}(Z)

256=361+324-684\cdot \text{cos}(Z)

256=685-684\cdot \text{cos}(Z)

256-685=685-685-684\cdot \text{cos}(Z)

-429=-684\cdot \text{cos}(Z)

\frac{-429}{-684}=\frac{-684\cdot \text{cos}(Z)}{-684}

0.627192982456=\text{cos}(Z)

\text{cos}(Z)=0.627192982456

Now, we will use inverse cosine or arc-cos to solve for angle Z as:

Z=\text{cos}^{-1}(0.627192982456)

Z=51.1566718^{\circ}

Z\approx 51^{\circ}

Therefore, the measure of angle Z is approximately 51 degrees.
