Answer:

10 gallons

Step-by-step explanation:

She used 12 gallons this week and used 20% more than last week. That means 12 gallons is 120% of last weeks gas. Since 12 times 10 equals 120, then to find 20% you do 20 divided 10 and subtract the answer from 12.

20% is 2 because 20 divided by 10 is 2. 12 minus 2 is 10

Hope this helps :)

Trina planted 43 plants in her garden last week. She planted twice as many cucumbers as zucchini and eight more tomatoes than cu

Naily [24]

She planted 7 zucchini, 14 cucumbers, and 22 tomatoes.

Let z = the number of zucchini planted. Since she planted twice as many cucumbers as zucchini, 2z is the number of cucumbers. She planted 8 more tomatoes than cucumbers, so 2z + 8 is the number of tomatoes. This gives us the equation

z + 2z + 2z + 8 = 43

Combining like terms, we have
5z + 8 = 43

Subtract 8 from each side:
5z + 8 - 8 = 43 - 8
5z = 35

Divide both sides by 5:
5z/5 = 35/5
z = 7

There were 7 zuccchini; 2*7 = 14 cucumbers; and 14+8=22 tomatoes.
