Which equations have the same value as 3/5 (30x-15)=72 select 3

const2013 [10]

Answer:

x=4.5

Step-by-step explanation:

Given the equation $\frac{3}{5}(30x-15)=72$ , we simplify as:

$\frac{3}{5}(30x-15)=72\\\\18x-9=72$

#We further simplify as multiples of 9(divide by 9 to solve for x):

$18x-9=72\\\\2x-1=8\\\\2x=9\\\\x=4.5$

Hence, from our simplification the equation has the same value as x=4.5

\dfrac{a^{m}}{a^{n}}=\dfrac{1}{a^{n-m}} \ if \ n > m\\$

$\dfrac{16r^{6}z^{3}}{8r^{2}z^{6}}=\dfrac{2r^{6-2}}{z^{6-3}}\\\\
=\dfrac{2r^{4}}{z^{3}}$

How do i solve 7x^{2} +11y^{2} =40

svetoff [14.1K]

Answer:

Step-by-step explanation:

There is no solution as you have two variables and only one equation. The best you can do is solve for one variable as a function of the other.

$7x^2+11y^2=40\\ \\ 11y^2=40-7x^2\\ \\ y^2=\frac{40-7x^2}{11}\\ \\ y=\sqrt{\frac{40-7x^2}{11}}$
