Combine like terms to create an equivalent expression.<br><br> 17−3(37n−27)71 −3( 73 n− 72)
patriot [66]

Answer:

\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})=1-\frac{9}{7}n

Step-by-step explanation:

Given : Expression \frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})

To find : Combine like terms to create an equivalent expression ?

Solution :

Step 1 - Write the expression,

\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})

Step 2 - Apply distributive property, a(b+c)=ab+ac

=\frac{1}{7}-3\times \frac{3}{7}n+3\times \frac{2}{7}

=\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}

Step 3 - Combine like terms,

=\frac{1}{7}+\frac{6}{7}-\frac{9}{7}n

=\frac{1+6}{7}-\frac{9}{7}n

=\frac{7}{7}-\frac{9}{7}n

=1-\frac{9}{7}n

Therefore,  \frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})=1-\frac{9}{7}n

How to do this problem because it's hard
Elenna [48]
You will need to set up and solve 2 equations:
A) 3 Vans + 10 Buses = 379
B) 14Vans + 13 Buses = 624
Multiply equation A by -14
A) -42 Vans -140 Buses = -5,306  then Multiply equation B by 3
B) 42 Vans + 39 Buses = 1,872
Adding BOTH equations
-101 Buses = -3,434
Each Bus holds 34 Students

Putting this into equation A
A) 3 Vans + 10 Buses = 379
A) 3 Vans + 10 * 34 = 379
A) 3 Vans +340 = 379
A) 3 Vans = 39
Each van = 13 students
