Actually Welcome to the concept of calculations of bills.

The bill calculation goes as equation,

y = $250 + n*($10)

here, n = number of lines,

1.) For n = 2 , Y = cost = 250 + 20 = $270

2.) for n = 4 , Y = $290

3.) for n = 6 , Y = $310

4.) for n = x, Y = $250 + x*($10)

for lastly 12 members we get as,

Y = 250 + (12)*(10) = 250+120 = $370

What else would need to be congruent to show that JKL= MNO by AAS?

taurus [48]

Answer: Choice B) Angle L = Angle O

---------------------------------------------------
---------------------------------------------------

If we know that Angle L is congruent to Angle O, then we can use the AAS (angle angle side) congruence property. We have one pair of angles marked by the square marker (angle J and angle M). So they are congruent angles. We have a pair of congruent sides JK = MN = 3. So we're just missing a pair of angles.

Note: The answer is NOT angle K = angle N because this would mean ASA would be used instead of AAS. The order of the letters is important as it establishes how the sides and angles relate. With ASA, the side is between the angles. With AAS, the side is not between the angles.

6. A factory has two types of machines.

Pie

210 pieces

Step-by-step explanation:

First, you need to figure out how many pieces a single machine can cut in a minute, so you need to divide 105 by 3, which gets you 35 pieces per minute.

Next, since we know there are 6 machines, and one machine canncut 35 pieces per minute, we can the figure out how many pieces all 6 cutting machines can cut in 1 minute. You would do this by making an equation such as this:

$35 \times 6 = x$

The x represents the total number of pieces cut by all 6 machines in one minute.

Next, since we now have an equation, we can go ahead and solve it. We would multiply 35 by 6, which would get us 210 pieces per minute that can be cut by all six machines

Simplify 3/4(1/2×-12)+4/5

Wittaler [7]

Answer: $\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

Step-by-step explanation:

Given the following expression:

$\frac{3}{4}(\frac{1}{2}x-12)+\frac{4}{5}$

You can follow these steps in order to simplify it:

1. You need to apply Distributive property:

$=\frac{3}{8}x-9+\frac{4}{5}$

2. And now you must add the like terms. Then:

$=\frac{3}{8}x-\frac{41}{5}$

Therefore you get the following answer:

$\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

Write an expression in factored form that is equivalent to the given expression. 1/2x + 4 . can u also tell how you solved it ?

Rufina [12.5K]

2 ways: Easy and hard
Hard=A
Easy=B
A: 1/2x+4 work from there so we do fun stuff with it make something that can be simplified so 1/2x+4 times (2/2)=x+8 now square the whole thing and put the result in a square root thingie (x+8)^2=x^2+16x+64 $\sqrt{x^2+16x+64}$ multiply the whole thing by 4/4 and put $\sqrt{16} [\tex] on top so then 
[tex] \sqrt{x^2+16x+64}$ times $\frac{ \sqrt{16} }{4}$ = $\frac{\sqrt{(16)(x^2+16x+64)}}{4}$ = $\frac{ \sqrt{16x^2+256x+1024} }{4}$ to solve it, factor out the 16 in the square root and then square root 16 to get 4 then it will be (4 times square root of equation)/4=square root of equatio factor square root of equation and square root it and get x+8 divide by 2 to get 1/2x+4

B: 1/2x+4
put stuff that cancels out
1/2x+3x-3x+4+56-56
move them around
3 and 1/2x-3x+60-56
or
2x-3x+1 and 1/2x+30-20+30-36
then just add like terms to solve

Which of the following is a solution of x2 + 4x = −8?

Vladimir [108]

$x^{2}+4x = -8
\\\\
x^{2}+4x+8 = 0
\\\\
\Delta = b^{2}-4ac
\\\\
\Delta = (4)^{2}-4 \cdot (1) \cdot (8)
\\\\
\Delta = 16-32
\\\\
\Delta = -16$

There's no solution in the set of real numbers.

$\boxed{S = \{ \ \ \}}$
