Shawna, Dexter, and Tilana are solving the equation Negative 2.5 (5 minus n) + 2 = 15.

Shawna says, “I can begin by dividing each side of the equation by –2.5 to get 5 minus n minus StartFraction 2 over 2.5 EndFraction = Negative StartFraction 15 over 2.5 EndFraction.”
Dexter says, “I can begin by distributing Negative 2.5 to get Negative 12.5 + 2.5 n + 2 = 15.”
Tilana says, “I can begin by multiplying each side of the equation by Negative StartFraction 1 over 2.5 EndFraction to get 5 minus n minus 0.8 = negative 6.”

2x+3y = -1

Answers

Answer:

Step-by-step explanation:

basically here we wanna get y by itself

so

2x + 3y = -1

subtract 2x from both sides

3y = -2x -1

then to get y by itself we have to divide everything by 3

y = -2/3x - 1/3

this is your equation in slope intercept form

hope this helps <3

Answer: y= -2/3 x -1/3

Explanation:

3y= -2x-1 (subtract 2x from 3y and transfer it to the other side)

y= -2x/3 -1/3 (divide 3 on both sides to leave y alone)

Final Answer: y= -2/3 x -1/3 (y equals to negative two-third x minus one-third)

Hayden had 2 1/2 gallons of water in his watering can. The seed packet said to use 1/4 of a gallon for peppers and 5/8 of a gallon for tomatoes. Hayden then used some of the water for lettuce. If Hayden had 3/4 gallons of water left over, about how much water did he use for lettuce?

i need it by 7 pm

Answers

Answer:7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce

Step-by-step explanation:1/4 + 5/8 = 2/8 + 5/8 = 7/8

= amount used for pepper and tomatoes

2 1/2 - 3/4 = 5/2-3/4 = 10/4 -3/4 = 7/4

= total amount used

so

7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce
