Answer:
d = 0.33
Step-by-step explanation:
First off, you want to get like terms next to each other. We'll move the numbers with variables on one side and normal numbers on the other. Since we're changing the sides of the equal sign they're on, this also changes whether their positive or negative.
d - d - 2d + 3d = 10 -7 + 8 - 10
Now that they're together, we can add or subtract them. The variables without numbers can be ones for this equation.
3d = 1
Now we divide 1 by 3 to find what d equals.
3d/3 = 1/3
d = 0.33
Answer:
<h2>x=(y-105)/7</h2>
Step-by-step explanation:
Given that the total time taken to practice is given by the expression as
y=7(15+x)
Simplifying the expression we have
y=105+7x
Solving for x (that is making x subject of formula we have)
7x=y-105
Divide both sides by 7 we have
x=(y-105)/7
Therefore the expression is
x=(y-105)/7
Answer:
![x^2\sqrt[3]{x}](https://tex.z-dn.net/?f=x%5E2%5Csqrt%5B3%5D%7Bx%7D)
Step-by-step explanation:
The relevant properties of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
1/a^b = a^-b
__
Your expression simplifies to ...
![\displaystyle x^{\frac{6}{3}+\frac{6}{9}-\frac{1}{3}}=x^{\frac{7}{3}}\\\\=x^2\sqrt[3]{x}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%5E%7B%5Cfrac%7B6%7D%7B3%7D%2B%5Cfrac%7B6%7D%7B9%7D-%5Cfrac%7B1%7D%7B3%7D%7D%3Dx%5E%7B%5Cfrac%7B7%7D%7B3%7D%7D%5C%5C%5C%5C%3Dx%5E2%5Csqrt%5B3%5D%7Bx%7D)
