Answer:

$\dfrac{2x}{3a^2}$

Step-by-step explanation:

$\dfrac{3a^4b}{2x}\cdot\dfrac{4x^2}{9a^6b}=\dfrac{3\cdot 4}{2\cdot 9}a^{4-6}b^{1-1}x^{2-1}=\dfrac{2x}{3a^2}$

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b

Jayden sells snow cones for $3.75 each. He started the day with a total of 300 snow cones to sell. If he made a total of $843.75

Leni [432]

Number of cone left is 75 cone

Given that;

Cost of each cone = $3.75 each

Starting number of cone = 300

Total amount earn = $843.75

Find:

Number of cone left

Computation:

Number of cone sale = Total amount earn / Cost of each cone

Number of cone sale = 843.75 / 3.75

Number of cone sale = 225 cone

Number of cone left = Starting number of cone - Number of cone sale

Number of cone left = 300 - 225

Number of cone left = 75 cone

Solve the following system of equations.

vodomira [7]

Answer:

a = 6/5

b = 7/8

c = 1/5

Step-by-step explanation:

We want to make two of these equations be in terms of the same variable, so let's solve the first and third in terms of b.

5a-24b=-15 -> -3 + 24b/5 = a

48b+35c = 49 -> 49/35 - 48b/35 = 7/5 - 48b/35 = c

Now we can replace the a and c in the second equation and solve for b.

10a+45c=21

10(-3+24b/5)+45(7/5 - 48b/35) = 21

-30 + 48b + 63 - 432b/7 = 21 -> -12 = -96b/7 -> b=7/8

Now we can plug b back into the other two to solve for a and c. I will leave that to you unless you would like the steps there.

If x^2 - 6x +8=0, then x-4=0 or x-2=0.

Dimas [21]

Step-by-step explanation:

X - 4 = 0

X = 4

X - 2 = 0

X = 2

So the values of x are 2 and 4
