(219,379.01 - x) / x = .3321
Ivahew [28]

Answer:x = 164686.592598

Step-by-step explanation:

219379.01−x/x = 0.3321

−x+219379.01/x = 0.3321

Step 1: Multiply both sides by x.

−x+219379.01≈0.3321x

−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)

−1.3321x + 219379.01 = 0

−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)

−1.3321x = −219379.01

−1.3321x/−1.3321 = −219379.01/−1.3321

(Divide both sides by -1.3321)

x = 164686.592598

Let n be the middle number of three consecutive Integers. Write an expression for the sum of these Integers.
dybincka [34]

Consecutive integers are those that occur one after the other. Let's use 2, 3, 4 as an example.


The middle number is 3 (n). To get to 2 from 3, we need to subtract 1 (n - 1). To get to 4 from 3, we need to add 1 (n + 1).

Now that we understand how to get to each number from the middle number, we can create our expression.

(n - 1) + n + (n + 1)

(n + n + n) + (1 - 1)

3n + 0

Answer: 3n

Hope this helps!

Andreyy89
Okay so we know that angle Q is a 90º angle. And angle M is the same as angle P which is 74º and we know that all triangles equal 180º so 180-74-90=16 so angle MNQ is 16º

Is (0,0) a solution to this system ?
Akimi4 [234]
The answer is choice B

The point (0,0) makes the first inequality true since
y >= x^2-4
0 >= 0^2-4
0 >= 0
is true

However, the point (0,0) does not make the second inequality true
y < 2x - 1
0 < 2(0) - 1
0 < -1
because 0 is not smaller than -1
