Reduce to the simplest form. -9/6 + (-3/5)
creativ13 [48]

Answer:

-\frac{21}{10} or -2.1 (they're the same)

Step-by-step explanation:

  1. Simplify: -\frac{9}{6} + (-\frac{3}{5}) = -\frac{9}{6} - \frac{3}{5}  
  2. Find a common denominator. The LCM of 6 and 5 is 30, so multiply the numerator and the denominator by the same thing: 6 × 5 = 30, -9 × 5 = -45, 5 × 6 = 30, 3 × 6 = 18
  3. Write the new fractions: -\frac{45}{30} - \frac{18}{30}  
  4. Subtract: -45/30 - 18/30 = -\frac{63}{30} = -\frac{21}{10}

I hope this helps!

The marching band sold gift wrap priced at $4.00 per roll for solid colors and $6.00 per roll for print patterns. If they sold 4
Alex Ar [27]

Answer:

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210

Step-by-step explanation:

Let

x ---> the number of gift wrap rolls for solid colors sold

y ---> the number of gift wrap rolls for sprint patterns sold

we know that

x+y=480 ---->x=480-y ----> equation A

4x+6y=2,340 ----> equation B

Solve the system by substitution

substitute equation A in equation B

4(480-y)+6y=2,340

solve for y

1,920-4y+6y=2,340

-4y+6y=2,340-1,920

2y=420

y=210

<em>Find the value of x</em>

x=480-y ----> x=480-210=270

therefore

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210
