Answer: x= 5

Step-by-step explanation: subtract 2x from both sides eliminating 2x.

4x-64=-44 add 64 to both sides eliminating -64

4x=20  divide by 4  

20/4 = 5

4x/4 = x

x= 5

Hope this helps :)

Answer:

90 days

Step-by-step explanation:

Let the rate per day for the 30 days period be x

Given that the rate drops to 1/3 of the rate used in 30 days period, it means that the new rate

= 1/3 x

If at a rate of x, the full tank runs for 30 days

at a rate of 1/3 x, the full tank would run for

= x/ (1/3 x) * 30 days

= 3 * 30 days

= 90 days

At the new rate, the full tank of oil will last for 90 days

Step-by-step explanation:

A= π r2

A = 3.14 times 16 squared

A = 803.84

Answer:

The equation is not an identity.

Step-by-step explanation:

Since we have Sin theta/cos theta + cos theta/sin theta = cos theta sin theta, we re-write as Sinθ/cosθ + cosθ/sinθ = cosθsinθ where theta = θ.

For the equation to be an identity, we need to show that L.H.S(left-hand-side)= R.H.S (right-hand-side)

So,

Sinθ/cosθ + cosθ/sinθ = (Sin²θ + cos²θ)/cosθsinθ (taking L.C.M = cosθsinθ)    

                                     = 1/cosθsinθ                         (Sin²θ + cos²θ = 1)

                                     ≠ cosθsinθ      

Since L.H.S = Sinθ/cosθ + cosθ/sinθ = 1/cosθsinθ ≠ R.H.S = cosθsinθ, the equation is not an identity.

Answer:

356 Seventh Graders

Step-by-step explanation:

All I did was find out what number 64 was 18% of, and that gave me the answer. I took 64 and put it over 18%, and set it across from X over 100%. I did the cross multiplication, and got 355.56, but rounded it to get 356. So there are 356 total seventh graders. Hope this is helpful...have a great day! :))

Step-by-step explanation:

Answer:

32 x p/100 = 40

(Solve for P)

Multiply by 100 on both sides

32x = 4,000

Divide by 32 to get:

X = 125%

(reason why you multiply by 100 is because opposite of division is multiplication and we multiply the number "100" because we always multiply the denominator to both sides when having a fraction so you can solve for p or whatever. And that means p/100 x 100 it means p because since p is not a known value we consider 1/100 x 100 = 1, a variable by itself means 1 so you could just put p by itself next to the number its multiplied by which is 32 so it would be 32p because your multiplying both and the opposite of that would be dividing by 32 on both sides because you are getting rid of the 32 so therefore you will be left with: X = 125)

Answer:

y=x/4

Step-by-step explanation:

add x to the other side of your equation so: 4y = x

now divide both sides by 4 so your y is isolated: y=x/4

Answer:  B= 11

Step-by-step explanation:

When n is equal to 4, the expression 6(n+8) - 5n evaluates to 52. This means that if we replace the variable n with 4, the expression simplifies to the constant value of 52.

To evaluate the expression 6(n+8) - 5n when n = 4, we substitute n with 4 and simplify step by step:

First, we substitute n with 4 in the expression:

6(4+8) - 5(4)

Next, we simplify the parentheses:

6(12) - 5(4)

Multiplying within the parentheses:

72 - 20

Finally, we subtract the two values:

52

As a result, the formula 6(n+8) - 5n evaluates to 52 when n is equal to 4. This indicates that the expression becomes simpler if we substitute the variable n with the number 4, which is 52.
