I'm having trouble with algebraic fractions . 3/2n-8/3=-29/12
nadezda [96]

what we can do is hmmmm get the LCD of all fractions, and multiply both sides by that LCD, let's see, we have denominators of 2, 3 and 12, so we can use the LCD of 12, and multiply both sides by 12 to do away with the denominators.

\bf \cfrac{3}{2}n-\cfrac{8}{3}=-\cfrac{29}{12}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{12}}{12\left( \cfrac{3}{2}n-\cfrac{8}{3} \right)=12\left( -\cfrac{29}{12} \right)}\implies (6)3n-(4)8=(1)-29 \\\\\\ 18n-32=-29\implies 18n=3\implies n=\cfrac{3}{18}\implies n=\cfrac{1}{6}

Simplify 4n5 + 3.5n5 + (-2.1n5).<br><br> 4.4 n5<br> 5.4 n5<br> 20 n5<br> 6.4 n5
ella [17]

Answer:

4 {n}^{5}  + 3.5 {n}^{5}  + ( - 2.1 {n}^{5} )

first create a bracket:

= ( {4n}^{5}  + 3.5 {n}^{5} ) + ( - 2.1 {n}^{5} )

then solve the first bracket:

=  {7.5 {n}^{5} } + ( - 2.1 {n}^{5} )

then open the remaining bracket:

=  {7.5n}^{5}  -  {2.1n}^{5}

carryout the subtraction operation:

= (7.5 - 2.1) {n}^{5}  \\ { \boxed{ =  {5.4n}^{5} }}
