Answer:

(A)

Step-by-step explanation:

Tamika's work is wrong as:

The given equation is:

\frac{18a^{-5}b^{-6}}{30a^3b^{-5}}

She added the components, while the components must be subtracted in this equation, thus the equation becomes

=\frac{3a^{-5}a^{-3}b^{-6}b^5}{5}

=\frac{3a^{-8}b^{-1}}{5}

=\frac{3}{5a^8b}

which is the required simplified form.

Thus, the option A is correct.

A video game designer is modeling a tower that is 320 ft high and 260ft wide. She creates a model so that the similarity ratio o
maksim [4K]
H = Tower Height = 320
W = Tower Width = 260
h = Model Height
w = Model Width

h = (1/500) * H = (1/500) * 320 = .64 feet
w = (1/500) * W = (1/500) * 260 = .52 feet

Now, we need to convert these measurements to inches.

There are 12 inches per foot.

Let x = height in inches and y = width in inches

The ratio below compares feet to inches

x / h = 12 in / 1 ft
y / w = 12 in / 1 ft

Plug in h and w, cross multiply, and solve for x and y, respectively.

x / .64 = 12 / 1
1 * x = .64 * 12
x = 7.68 in

y / .52 = 12 in / 1 ft
1 * y = .52 * 12
y = 6.24 in

Find 3 consecutive numbers that equal 45
tatyana61 [14]

Answer:

14,15,16

Step-by-step explanation:

Let x be the first number

Consecutive means in a row

x+1 is the second number

x+2 is the third number

x+ x+1 + x+2 = 45

Combine like terms

3x+3 = 45

Subtract 3 from each side

3x+3-3=45-3

3x = 42

Divide each side by 3

3x/3 = 42/3

x =14

The first number is 14

The second number is  14+1 = 15

The third number is 14+2 =16
