Answer:

1- y= -1.25x+15.5 because you can estimate the y intercept to see that it intercepts at 15.5 and you find the slope by calculating it with the points 2,15 and 6,10.

2- it decreased approximately 1 and a half minutes a day  because the slope is -1.25, or one and a half minutes lost

Step-by-step explanation:

6-2/10-15=-1.25

Lisa has $7.80 to spend on some tomatoes and a loaf of bread. Tomatoes
Sunny_sXe [5.5K]

Answer:

Lisa can buy 5 pounds of tomatoes.

Step-by-step explanation:

Given that Lisa has $ 7.80 to spend on some tomatoes and a loaf of bread, and tomatoes cost $ 1.20 per pound, and a loaf of bread costs $ 1.80, to determine how many pounds of tomatoes she can buy, the following calculation must be performed:

1.20X + 1.80 = 7.80

1.20X = 7.80 - 1.80

X = 6 / 1.20

X = 5

So Lisa can buy 5 pounds of tomatoes.

lisa drank 1/3 quart of orange juice and lane drank 1/2 quart of orange juice. how many quarts did they drink together
mezya [45]

Answer:

\frac{5}{6} quarts

Step-by-step explanation:

Total amount of drinks = \frac{1}{3} + \frac{1}{2}

You would want to make the denominators the same before adding them, so I will multiply the first fraction by 2 and the second one by 3 so their denominators are 6.  

\frac{1}{3} + \frac{1}{2} = \frac{2}{6} + \frac{3}{6}

Now we can directly add them together while keeping the denominator the same.

\frac{2}{6} + \frac{3}{6} = \frac{5}{6} quarts
