Answer:
Third one one
(1 x^8/ 2^2y^5)^3
Step-by-step explanation:
Quotient of power: a^m/a^n = a^(m-n)
[(x^3y^-2) /(2^2x^-5y^3)]^3 = (x^8/ 2^2y^5)^3
So. It's third option
Answer:
m=E/c².
Step-by-step explanation:
Transposing the formula
E=mc²
we divide both sides by c² then cancel out where necessary so m would stand alone
E/c²=mc²/c²
cancelling c² on the right hand side, equation becomes
m= E/c²
Answer:
1. a = 2
2. x = 12
3. w = 2
Step-by-step explanation:
1. ok so 2a/5 we would want to separate it to 2/5 and a/5
2/5 x a/5 = 2a/5
next we want to subtract 2/5 from 8/10
8/10 - 2/5 or 8/10 - 4/10 = 4/10
now you have a/5 and 4/10
a/5 = 4/10
now you multiply each side by 5
a/5 x 5 = a
4/10 x 5 = 20/10 or 2
a = 2
2. ok so the x is kinda on it's own for this one but we still wan to get the x and the other numbers on opposite sides
1/16x + 1/4 - 1/4 = 1/16x
1/2 + 1/4 = 3/4
now we do that same last step
1/16x / 1/16 = x
3/4 / 1/16 = 12
x = 12
3. ill do one more and if you need more help just tell me
for this on we have the w on both sides so we have to get the variable(w) and the numbers on opposite sides
2w - 2 + 2 = 2w
1/2w + 7 - 1/2w = 7
2w + 1/2w = 5/2w or 2 1/2w
7 - 2 = 5
now we have to divide each side by 5/12 or 2 1/2
5/2w / 5/2 = w
5 / 5/2 = 2
w = 2
0.002. You have to do 1 divided by 500. Or you can just add a zero behind the decimal because it's 500 and it has 2 zeros and you already know that 1/50=0.02
For the answer to the question above asking to<span> write an expression to model its age in dog years</span><span> for a dog that is 2 years old or older. If x is equal to human age
then the dog is 2 years older
X = human years
x + 2 = is for the dog age
