Please tell me how do you simplify the expression???? <br> x^15 · y^9<br> over<br> x^8 · y^3

anyanavicka [17]

Answer:

$x^7 * y^6$

Step-by-step explanation:

In the equation: $\frac{x^{15} * y^9 }{x^8 * y^3}$

x's can be simplified and y's can be simplified!

Always remember that for exponents, you subtract the powers when dividing

so for x: 15-8 = 7

for y: 9-3 = 6

so the final answer is: $x^7 * y^6$

Oliga [24]

I can answer 18 for you, but I don't understand 16

18. Since when we lose 3 girls the ratio for the girls side drops by 1, that tells us that 1 digit equals 3 people.

a) 5*3=15 so our answer is 15 girls.

b) 4*3=12 and 5*3=15 so 15+12, our answer would be 27

VikaD [51]

Answer:

The distance cover by him walking back is 11.25 miles

Step-by-step explanation:

Given as :

Time for Janelle to spend on training = 5 hours

The running speed of Janelle = 9 mph

The walking back with 3 mph

Let The distance for running and walking is same i.e D miles

SO, Time = $\frac{Distance}{Speed}$

∴ 5 = $\frac{D}{9}$ + $\frac{D}{3}$

Or, 5 × 9 = D + 3 D

Or, 45 = 4 D

∴ D = $\frac{45}{4}$ = 11.25 miles

Hence The distance cover by him walking back is 11.25 miles Answer
