2. John and Jen went to the farmers market to buy fruit. John bought 3 boxes of oranges and 9 boxes of cherries for $78. Jen bou

jenyasd209 [6]

Answer:

Let the cost of orange be X and cost of cherry be y

3x + 9y = 78

8x + 4y = 58

Solving equation using elimination method

multiplying eq 1 with 8 and eq 2 with 3

8(3x + 9y ) = 78(8)

3( 8x + 4y) = 3(58)

24x + 72 y = 624

24x + 12y = 174

subtracting,

60 y = 450

y = 7.5

3x + 9(7.5) = 78

3x + 67.5 = 78

3x = 78 - 67.5

3x = 10.5

x = 3.5

<h2>Box of orange = $3.5 </h2><h2>Box of cherry = $7.5</h2>

Which of the followeing represents the solution...<br><br> 4(9+3z)≤12+6z

julia-pushkina [17]

Solving the inequality $4(9+3z)\leq 12+6z$ we get $z\leq -4$

Step-by-step explanation:

We need to solve the inequality $4(9+3z)\leq 12+6z$

Solving:

$4(9+3z)\leq 12+6z$

Multiplying 4 with terms inside the bracket.

$36+12z\leq 12+6z$

Adding -36 on both sides:

$12z\leq 12+6z-36$

Adding -6z on both sides

$12z-6z\leq 12-36$

$6z\leq -24$

Divide both sides by 6

$z\leq -4$

So, solving the inequality $4(9+3z)\leq 12+6z$ we get $z\leq -4$
