Step-by-step explanation:
15/4 + (−4/13) can be rewritten as 15/4-4/13.
15/4-4/13
15 x13
4 x13
195/52
4 x4
13 x4
16/52
195/52-16/52=179/52 or 3 23/52

Answer:
the scenic route take 6h 40m
Step-by-step explanation:
first we have to make an equation that represents the relationship of each route
x = scenic route
y = direct route
x = y + y * 25/100
now we have to make an equation that represents the routes over time
x + y = 12
we replace the x by what is the same in the first equation (y + y * 25/100) in the second equation
x + y = 12
(y + y * 25/100) + y = 12
2 y + 0.25 y = 12
2.25y = 12
y = 12/2.25
if we spend this in minutes multiplying it by 60
y = 12/2.25 * 60 = 320 m = 5h 20m
x + y = 12
x + (5h 20m) = 12h
x = 12h - 5h 20m
x = 6h 40m
Answer:
The correct answer is option D. Dilation by a scale factor of 2 followed by reflection about the x-axis
In monetary terms, you're making change. If you need more ones, you trade one 10 for 10 ones.
When I was in school, many years ago, we used small superscript-type numbers to show this:
7 3 0 ⇒ 7 2 ¹0 . . . . regrouping to gain 10 ones
7 2 ¹0 ⇒ 6 ¹2 ¹0 . . .regrouping again to gain 10 more tens
