Simplify rational expression
zubka84 [21]

Answer:

<u>The final answer is 35n/17r</u>

Step-by-step explanation:

Let's simplify the expression, this way:

1. Start with the coefficients:

(10 * 42)/(6 * 34)

We cancel 6 in the denominator and change 42 by 7. Now we have:

(10 * 7)/34

We now divide by 2 both in the numerator and the denominator. Now we have:

(5 * 7)/17.

The remaining numbers are prime numbers and it's not possible to continue simplifying, so we got:

35/17

2. Variable r:

We have r⁴/r⁵ = r ⁴⁻⁵ = r⁻¹ = 1/r¹ = 1/r

3. Variable n:

We have n⁴/n³ = n ⁴⁻³ = n¹/1 = n

4. Adding the pieces:

We put coefficients and variables together: 35/17 * 1/r * n

<u>The final answer is 35n/17r</u>

The scale used for a model of a kitchen is 1/4 in. = 1.5 ft. In the model,
fgiga [73]

Answer:

15ft by 18ft

Step-by-step explanation:

Start with 2.5 divided by .25

That equals 10

10 times 1.5 ,because we know it takes ten .25inches to equal 2.5 and 2.5, is the size of one of the sides.

10 time 1.5 is 15ft

3 divided by .25 is 12

using the same logic and math as stated above we know 3 x .25 equals 12 by 12 quarter inches to make 3 inches

12 x 1.5 Same logic as before

12 x 1.5 equals 18ft

The kitchen is 15ft by 18ft
