4y=2x-10 and y=6

use the second expression to calculate the left-hand side of the first equation:

4\cdot 6 = 2x -10\\24 = 2x -10

Add 10 to both sides if this equation to get

34 = 2x

and divide both sides by 2

17 = x

this proves that x = 17, give the two initial equations

A bee flies at 10 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 18 minutes, and then
uysha [10]

Answer:

Step-by-step explanation:

d = distance from hive to flowers, in feet

flying time = 23 min - 18 min = 5 min = 300 sec

time flying to flowers = d ft × (1 sec)/(10 ft) = (d/10) sec

time flying to hive = d ft × (1 sec)/(6 ft) = (d/6) sec

d/10 + d/6 = 300 sec

:::::

d/10 + d/6 = 3d/30 +5d/30 = 8d/30 = 300

d = 300×30/8 = 1,125 ft

AleksAgata [21]

Answer: 3

<u>Step-by-step explanation:</u>

 <u>Wins</u>      <u>Losses</u>            <u>Pattern</u>

   18             2               18 ÷ 2 = 9

   45            5               45 ÷ 5 = 9

   36            4               36 ÷ 4 = 9

   27            x

Using the same pattern we have  

  27 ÷ x = 9    

→        x = 3
