Since you can spend  $48 so you can buy 16 items in either ways . let x be  for hot dogs and y for hamburgers.
8x+20y=48
20x+4y=48
6x+21y=48
22x+13y=48

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 14 miles per hou
Sergeu [11.5K]

Answer:

The answer to your question is 166 mi/h

Step-by-step explanation:

Data

ve = rate eastbound train

vw = rate westbound train = ve - 14

distance = d = 900 mi

time = t = 5 h

Formula

v = \frac{distance}{time} = \frac{d}{t}

Substitution and simplification

ve = \frac{900}{5} = 180 mi/h

Now, substitute this value in the equation of vw

vw = 180 - 14

Result

vw = 166 mi/h

Round 421,906 to the nearest hundred thousand and to the nearest thousand
mojhsa [17]
421906 can be partitioned to 400000 + 20000 + 1000 + 900 + 00 + 6

The number 421906 is in between 400000 and 500000, but it's closer to 400000, so rounding to the nearest hundred thousand gives 400000

The number 421906 is in between 421000 and 422000, but it's closer to 422000, so the nearest thousand is 422000

M is the midpoint of CD. C has coordinates (-1, -1) and
olga_2 [115]

Answer:

(7, 11)

Step-by-step explanation:

If a line segment has endpoints at A(x_1,y_1) and B(x_2,y_2), the coordinates of the midpoint O(x, y) of the segment AB is given by the formula:

x=\frac{x_1+x_2}{2}\\\\y=\frac{y_1+y_2}{2}

Given the midpoint M(3, 5) of the segment CD with the coordinates of C at (-1, -1). Let the coordinates of D be at (x_2,y_2). Hence:

x=\frac{x_1+x_2}{2}\\\\ 3=\frac{-1+x_2}{2} \\\\6=-1+x_2\\\\x_2=6+1\\\\x_2=7\\\\y=\frac{y_1+y_2}{2}\\\\ 5=\frac{-1+y_2}{2} \\\\10=-1+y_2\\\\y_2=10+1\\\\y_2=11

Hence the coordinates of D is at (7, 11)
