7:25 P.M.

Step-by-step explanation:

Add 2:25, 1:25, and 2:40 = 6:30 and add that to 12:55= 19:25 which is also equal to 7:25 P.M.

Write an equation of a line with the slope of 1 and y-intercept of 4
Rashid [163]

Answer (<u>assuming it can be in slope-intercept form)</u>:

y = x + 4

Step-by-step explanation:

With the given information, we can write the equation of the line in slope-intercept form. Use the slope-intercept formula, y = mx + b, and substitute values for m and b.

The m, or the coefficient of the x-term, represents the slope, so substitute 1 in its place. The b represents the y-intercept, so substitute 4 in its place. This gives the following answer:

y = x + 4

(Remember that the coefficient of the x-term, 1, is still there. However, instead of 1x, we can just write it as x.)

Janet is mixing a 15% glucose solution with a 35% glucose solution. This mixture produces 35 liters of a 19% glucose solution. H
andrey2020 [161]

Answer:

We'll be making 35 liters of 19% glucose.

How much of a 15% solution and a 35% solution do we mix in order to get 35 liters of a 19% glucose solution?

X = liters of 15% and Y = liters of 35%

(.15 X + .35 Y) / 35 = .19

The number of Y liters will equal (35 -X) so the equation becomes

(.15 X + .35 *(35-X) ) / 35 = .19

(.15X + 12.25 -.35X) / 35 = .19

(-.20 X / 35) + (12.25 / 35) = .19

(-.20 X / 35) + .35 = .19

(-.20 X / 35) = -.16

-.20X = -5.6

X = 28 liters of 15% and

Y = 7 liters of 35% glucose

Answer is "c" 28 liters
