The answer is x = 2 because you have to distribute 5 to x and +1 causing it to be 5x + 5 + 6 and then you combine ( 5x+11)=21 and then it’s an easy solve after that.

Find the value of x. Round to the nearest tenth.
Aliun [14]

Answer:

Step-by-step explanation:

Triangle XYZ is a right angle triangle.

From the given right angle triangle

XZ represents the hypotenuse of the right angle triangle.

With ∠34 as the reference angle,

YZ represents the adjacent side of the right angle triangle.

XY represents the opposite side of the right angle triangle.

To determine x, we would apply the Cosine trigonometric ratio

Cos θ = opposite side/hypotenuse. Therefore,

Cos 34 = x/28

x = 28Cos34 = 28 × 0.8290

x = 23.212

To the nearest tenth, it becomes

23.2

The total charge on 4 particles is −36 units. All the particles have the same charge.
xxMikexx [17]

We are given

total number of particles =4

and

total sum of charge=-36

Since, all the particles have the same charge

and total charge is negative

so, charge on each particle must be negative

now, we can use formula to find change on each particle

charge on each particle = (total sum of charge)/( total number of particles)

now, we can plug values

and we get

The charge on each particle is

=\frac{-36}{4}

=-9 units..............Answer

yes i agree because if all the integers are positive, the answer stays positive which means if you know your integer rules: a positive divide by a positive it stays positive. its the same thing for all the other operations. hope this helps.
