1) you can divide both 10 and six by 2 so you’d be left with 5y^7/ 3y^2

2) subtract the y^2 from the y^7 to get y^5

3) leave the y^5 on the top because y^7 was the bigger exponent and it was on the top in the beginning.

4) the answer is 5y^5/3

GaryK [48]

Step-by-step explanation:

$p\%=\dfrac{p}{100}$

$a)\\20\%=\dfrac{20}{100}=\dfrac{2}{10}=0.2\\\\20\%\ of\ \£150\to0.2\cdot\£150=\£30\\\\b)\\15\%=\dfrac{15}{100}=0.15\\\\15\%\ of\ 80kg\to0.15\cdot80kg=12kg\\\\c)\\85\%=\dfrac{85}{100}=0.85\\\\85\%\ of\ 2500m\to0.85\cdot2500m=2125m$

Answer:

x = -3/2

Step-by-step explanation:

7⁰ = 1 (anything to the power of 0 equals 1)

7²ˣ ⁺ ³ = 7⁰

Since the bases are the same, you 'forget' about the bases and then you solve for x.

2x + 3 = 0

2x = -3

x = -3/2

suter [353]

Answer:

$\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}$

Step-by-step explanation:

To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.

$\frac{3}{25}, \frac{\sqrt{3}}{11}, \frac{9}{100},\frac{\pi }{24}$
