Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.
nataly862011 [7]

Answer:

Step-by-step explanation:

x = small barrettes

y = large barrettes

13x + 11y = 142.......multiply by -1

13x + 12y = 149

-----------------------

-13x - 11y = -142 (result of multiplying by -1)

13x + 12y = 149

------------------------add

y = 7..........large barrettes used 7 yards

13x + 11y = 142

13x + 11(7) = 142

13x + 77 = 142

13x = 142 - 77

13x = 65

x = 65/13

x = 5........small barrettes used 5 yards

Ainat [17]

Answer:

\Huge\boxed{z

Step-by-step explanation:

Hello There!

Once again we need to isolate the variable using inverse operations

to get rid of the -8.2 we add 8.2 to each side

-8.2+8.2 cancels out

-9.7+8.2=-1.5

now we have

-1.2z>-1.5

now we wan to get rid of the -1.2

to do so we want to divide each side by -1.2

\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25

Remember we have to flip the inequality sign because we're dividing by a negative number

we're left with

z<1.25
