What value of x satisfies the equation 5x+1.5=7

Answers

Answer 1

Answer: First thing we are going to do to solve this is to subtract 1.5 from both sides so:
5x+1.5−1.5=7−1.5
5x=5.5
Next we are going to divide from both sides by 5 so:
5x/5=5.5/5
Finally your final answer shall be:
x=1.1

I hope this helps!

Answer 2

Answer: 5x+1.5=7
-1.5 -1.5
--------------
5x = 5.5
---- ------
5 5

x = 1.1

subtract 1.5 from both sides, then with that answer, you divide it by 5.
x = 1.1

In the diagram below, AE = 4, EB = 3, and DE = 2. Find CE.

Answers

Answer: Value of CE = 6.

Explanation:

Since we have given that

AE=4

BE=3

DE=2

Let CE be x.

As we know that

When two chords intersect each other inside a circle, the products of their segments are equal.

Here, we can see that each chord is cut into two segments at the point of where they intersect.

So,

$EA.EB=EC.ED\n\n4* 3=x* 2\n\n12=2x\n\n(12)/(2)=x\n\n6=x$

Hence, value of CE = 6.

How do you " find, to the nearest tenth of an inch, the diagonal of a square whose perimeter is 28 inches ?"

Answers

Well if the perimeter is 28 inches, each side of the square is 7 inches. 28/4 = 7 because all sides of a square are the same.

If we split the square in half to create 2 triangles we can find the length of the diagonal. The two sides are the bases of 7 inches.

Use the Pythagorean theorem to solve for the hypotenuse or the diagonal.

7^2 + 7^2 = diagonal ^ 2

Therefore, the diagonal equals 9.9 inches.

The peak value of sinusoidal ac current of 4.78rms is a. 5.45 amp b. 6.76 amp c. 4.56 amp d. 4.78 amp

Answers

Answer:

To find the peak value of a sinusoidal alternating current given its RMS (Root Mean Square) value, you can use the relationship between peak value and RMS value for a sinusoidal waveform.

The relationship is given by:

Peak Value = RMS Value * √2

In this case, the RMS value is 4.78 amp. Plugging this into the equation, we get:

Peak Value = 4.78 amp * √2 ≈ 6.76 amp

Therefore, the correct answer is option b) 6.76 amp.
