I have the first part down, but I don't understand how to solve. It's an inequality.

Anna71 [15]

Answer:

As shown in your game, you have an inequality:

2.5 x h + 10.9 > 33.4

=> 2.5 x h > 33.4 - 10.9

=> 2.5 x h > 22.5

=> h > 22.5/2.5

=> h > 9

Solve the system of equations using substitution.

faltersainse [42]

Answer:

( $\frac{1}{3}$ , 3 )

Step-by-step explanation:

Given the 2 equations

y = 9x → (1)

6x - y = - 1 → (2)

Substitute y = 9x into (2)

6x - 9x = - 1, that is

- 3x = - 1 ( divide both sides by - 3 )

x = $\frac{1}{3}$

Substitute x = $\frac{1}{3}$ into (1) for corresponding value of y

y = 9 × $\frac{1}{3}$ = 3

Solution is ( $\frac{1}{3}$ , 3 )
