to win the neighborhood tomato growing contest jonny needs for his tomato plant to produce 8 tomatoes per week. he needs 30 tomatoes to win the contest. he already has 6 tomatoes. write and solve an equation to find the number of weeks he needs to produce 30 tomatoes.

t=3

Step-by-step explanation:

Equation: 8t represent the rate of 8 tomatoes per week + 6 to represent the tomatoes the already has. And the 30 is for the 30 tomatoes he needs to win.

30=8t +6

-6        -6

24=8t (divide both sides by 8) Final answer is t=3

2x + 3y – z = 1 (1)3x + y + 2z = 1 (2)2x + 2y – 3z = –5 (3)Multiply equation (1) by 24x+6y-2z=2 3x + y + 2z = 1 (2)Add:7x+7y = 3 (4)Multiply equation (1) by -3-6x-9y+3z = -32x + 2y- 3z = –5 (3)Add:-4x-7y=-8 ---(5)Solve equations (4) and (5)7x+7y = 3 (4)-4x-7y=-8 ---(5)Add:3x= -5x=-5/3
