A Broadway musical was attended by a total of 2,838 people, including men, women, and children. The number of women who attended
liberstina [14]
M + w + c = 2838
w = 3c + 5
m = 4w - 3......4(3c + 5)- 3 = 12c + 20 - 3 = 12c + 17

(12c + 17) + (3c + 5) + c = 2838 .....combine like terms
16c + 22 = 2838
16c = 2838 - 22
16c = 2816
c = 2816/16
c = 176 <==== children

w = 3c + 5
w = 3(176) + 5
w = 533 <=== women

m = 12c + 17
m = 12(176) + 17
m = 2129 <=== men

What is the value of 7 ^−3 ^ −1 for = −2 and = 4?
andrey2020 [161]

Answer:

d. −7/32

Step-by-step explanation:

The expression that we have to evaluate in this problem is:

7x^{-3}y^{-1}

We have to evaluate this expression for:

x = -2

y = 4

We start by rewriting the expression by rewriting it using the following:

a^{-n}=\frac{1}{a^n}

So the expression can be rewritten as

7x^{-3}y^{-1}=\frac{7}{x^3 y}

Now we observe that:

(-2)^3=(-2)(-2)(-2)=-8

Therefore, by substituting x = -2 and y = 4 into the expression, we find:

\frac{7}{(-2)^3\cdot 4}=\frac{7}{-8\cdot 4}=-\frac{7}{32}
