sergiy2304 [10]

Answer:

[see below]

Step-by-step explanation:

We can tell that for every hour passed the distance traveled by the train would increase by 40 miles.

We can use the equation d = 40t to determine the values of the table. The 'd' is total distance and 't' is the number of given hours.

Two hours:

d = 40(2)

d = 80

Three Hours:

d = 40(3)

d = 120

Four Hours:

d = 40(4)

d = 160

Hope this helps.

The triangles are similar. <br> What is the value of x?<br><br> x =
saveliy_v [14]

Answer:

x = 23

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{39}{x-10} = \frac{36}{12} = \frac{15}{5} = 3

multiply both sides by (x - 10)

3(x - 10) = 39 ( divide both sides by 3 )

x - 10 = 13 ( add 10 to both sides )

x = 23

Brian and Zack went to the store and bought packs of gum. Brian bought 3 less packs than twice the number zack bought. Together
balu736 [363]

Answer:

  • Zack: 11
  • Brian: 19

Step-by-step explanation:

Let z and b represent the number of packs that Zack and Brian bought, respectively. Then the problem statement tells us ...

  b = 2z -3 . . . . . . . Brian bought 3 fewer than twice what Zack bought

  b + z = 30 . . . . . . they bought a total of 30 packs

Using the first equation to substitute into the second, we have ...

  (2z -3) +z = 30

  3z -3 = 30

  3z = 33 . . . . . . add 3

  z = 11

  b = 2·11 -3 = 22 -3 = 19

_____

<em>Check</em>

  b + z = 19 + 11 = 30 . . . . answer checks OK

Zack bought 11 packs; Brian bought 19 packs of gum.
