Does x=1.6 satisfy the equation 6-4x=-x/4? explain

Answers

plug 1.6 in for x to see if it is correct:
6- 4x= -x/4

6- 4(1.6)= -(1.6)/4 (divide -1.6 and 4)

6-4(1.6)= -0.4 (multiply 1.6 and -4)

6-6.4= -0.4 (subtract 6 and 6.4)

-0.4=-0.4

-0.4 does equal -0.4. so that means that x does equal 1.6.

Final answer:

Substituting x=1.6 into the equation 6-4x=-x/4 doesn't result in an equality, hence, x=1.6 doesn't satisfy this equation.

Explanation:

To verify if x=1.6 satisfies the equation 6-4x=-x/4, we just need to substitute 1.6 in the place of x in the equation and check if both sides of the equation balance. The left side of the equation would then be: 6-4(1.6) = 0.4. The right side of the equation becomes: -1.6/4 = -0.4. As we can see the left side of the equation doesn't equal the right side, hence, x=1.6 doesn't satisfy the equation 6-4x=-x/4.

Bill measures the circumference of a circular fish pond to be 28 ft.What is the diameter of the fish pond, rounded to the nearest foot?
Use 3.14 to approximate pi.

ft

Answers

9ft? to get the circumference, we multiply the diameter to pi, so all we need to do is divide 28 ÷ π, and round.

9ft because to get circumference you multiply by π (pi or 3.14) so to get circumference you just do it the other way around like: 28 ➗π (3.14) = 8.91710... Which rounds to 9. So, the diameter is 9ft. I hope I helped and just message me if you need anything else!

HELPJames will draw a rectangle with an area of 25 square inches. Which set of measurements can James use?

A.length =5 1/2
width =5 in.
B. Length= 5 3/4 width 4 3/4 in.
C. Length 12 1/2
Width = 2 in.
D. Length 12 1/2
Width 12 1/2 inches

Then figure out the perimeter of the rectangle you selected

Answers

The answer for your question is A. The reason why it's a is because the are for the rectangle is 25. So your answer has to be 25. So for A the length is 5 1/2 so divide 1/2 you will get 0.5 then multiply 0.5 to 5 that will give you 25. The for Width it's the same thing so you divide 25 into 5 you will get 5 and multiply 5 times that will give you 25.

Hope this helps:)

There are 105 lettered tiles in a board game. You choose thetiles shown (R, A, I, L, M, B, E). How many of the 105 tileswould you expect to be vowels?

Answers

Answer: 45

Step-by-step explanation:

Given: The total number of lettered tiles in a board game =105

The number of tiles chosen (R, A, I, L, M, B, E) = 7

the number of vowels chosen (A,I,E)=3

Now, the fraction or probability of choosing of vowels out of 7 given letters is given by :-

$\text{P(vowels)}=(3)/(7)$

Now, the number of vowels we can expect to be vowels out of 105 letters is given by :-

$\text{P(vowels)}*\text{Total letters}=(3)/(7)*105=45$

Hence, the number of vowels we can expect to be vowels out of 105 letters is 45.

105 ÷ 7 = 15 15 × 3 = 45 45 are vowels
