Answer:

B

Step-by-step explanation:

My teacher just told me

Answer: If your asking what c is its 9

Step-by-step explanation: How I did it was I did 72/8, which is 9. How I checked was I did 8*9 and I got 72

C is 9 if you multiply 8 and c to get 72.

Answer:

1250 women

Step-by-step explanation:

1500 / 6 = 250

250 x 5 = 1250

hope this helps

Answer:

There are 1,250 women

Step-by-step explanation:

If the ratio of men to women is 6 to 5, and there are 1,500 men, the actual ratio of men to women is 1,500 to x, where x is equal to the amount of women at the college.

Since 6/5 is equal to 1,500/x, you cross multiply to find that 7,500 is eual to 6x.

Divide both sides by 6 to find that x is equal to 1,250 women.

Answer:

  C.  The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).

Step-by-step explanation:

The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.

The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.

Additionally, the x-term needs to match the result of multiplying out the factors.

  B.  (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)

  C.  (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)

The factors of C are zero when x=-1, x=5/2.

Answer:

120 children and 388 adults bought tickets for the swimming pool

Explanation:

Create two simultanous equations:

Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being

c

+

a

=

508

then, you now create a second equation for the prices of the tickets.

(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected

so:

1.75

c

+

2.25

a

=

1083.00

now we still know, that

a

=

508

−

c

so we can substitute it into the second formula

1.75

c

+

2.25

(

508

−

c

)

=

1083

now its just simple algebra

1.75

c

+

1143

−

2.25

c

=

1083

60

=

0.5

c

so:

c

=

120

now we know, that 120 children went to the swimming pool.

and we still have the formula from before:

a

=

508

−

c

so

a

=

388

Answer:

A . 496 ft²

Step-by-step explanation:

Area = ½ × base × height

= ½ × 62 × 16

=496 ft²

Hey there!

One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us [tex]\frac{-81x+27}{3}[/tex]. If we simplify this, we get [tex]-27x+9[/tex].

Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us [tex]\frac{-81x+27}{21}[/tex]. If we simplify this, we get [tex]-3x+1[/tex].

One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us [tex]1(-81x+27)+0[/tex].

Have a terrificly amazing day! :D

Answer:

M = 95°

N = 67°

Step-by-step explanation:

180 - 162 = 18°

6y + 5 + 4y + 7 + 18 = 180

10y + 30 = 180

10y = 150

y = 15

M: 6(15) + 5 = 95°

N: 4(15) + 7 = 67°

Verification: 95 + 67 + 18 = 180° (correct)

Answer:

they are related because they are across the x axis

Answer:

[tex]x=-15.5[/tex]

Step-by-step explanation:

Write down what the problem is saying;

[tex]6(x+9)=2(x-4)[/tex]

Distribute;

[tex]6(x+9)=2(x-4)\\\\(6)(x)+(9)(6)=(2)(x)+(2)(-4)\\[/tex]

Simplify,

[tex]6x + 54 = 2x - 8[/tex]

Inverse operations,

[tex]6x + 54 = 2x - 8\\-2x\\\\4x + 54 = -8\\-54\\\\4x = - 62\\/4\\\\x =-15.5[/tex]

Step-by-step explanation:

the reason is bc there are 5 zero's after the decimal

9514 1404 393

Explanation:

A linear system of two equations in two variables will be a dependent system. This means both equations reduce to the same equation. The equations will be different only until they are reduced to the same form.

Here is one possible set of equations. The first is in slope-intercept form. The second is in point-slope form.

If we subtract the first equation from the second, we get ...

  (y -7) -(y) = (3(x -2)) -(3x +1)

  -7 = 3x -6 -3x -1 . . . . . eliminates y

  -7 = -7 . . . . . . . . . true for all values of x

There are an infinite number of solutions.

Answer:

Step-by-step explanation:

Given the value 141700000, we are to express in scientific notation

The standard form is expressed as A * 10^n

A is any integer between 1 and 10

n is also any integer

141700000.= 1.47 * 10^8

Note that the decimal point was shifted back 8 times, main reason the power is 8
