Answer:

  1. c = -4.5
  2. z = 20
  3. x = -12
  4. a = -4/7

Step-by-step explanation:

A way to do this that will always work is ...

  • eliminate parenthses and collect terms
  • subtract any constants from the left side
  • subtract any variable terms from the right side
  • divide by the coefficient of the variable

1.

  • 8c -11 -6c = -2
  • 2c -11 = -2
  • 2c = 9
  • c = 4.5

2.

  • 3z +4 -2z -9 = 15
  • z -5 = 15
  • z = 20

3.

  • 12 -4x +18 = 36 +4x +18 -6x
  • 30 -4x = 54 -2x
  • -4x = 24 -2x
  • -2x = 24
  • x = -12

4.

  • 36a -9a -5 = 6a -17
  • 27a -5 = 6a -17
  • 27a = 6a -12
  • 21a = -12
  • a = -12/21 = -4/7

Please help this is due tommorow and I need answers to these questions
Dmitrij [34]

Answer:

Step-by-step explanation:

a) The equation we can use is:

<u>d = s x t</u>

d = distance

s = speed

t = time

b)

There's a clue giving us the information that how long the bee flies directly back to the hive, it is known that it is <u>away from the hive for 13 minutes</u> while the bee <u>stays at the flowerbed for only 11 minutes</u>.

=> So we can assume that the bee flies back to the hive at the speed of 4 feet per second for 2 minutes

Using the equation above, we can write that: 6 x 60 x 2 = 720 ft

=> So in the end, the distance of the flowerbed from the hive is 720 ft

<em>c) I don't really understand this question</em>

Kathy ran the 400-meter dash in 60.48 seconds. She ran the 200 meter dash in 28.9 seconds.If she divided her 400-meter dash time
nika2105 [10]

Answer:

Kathy would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.

Step-by-step explanation:

Kathy ran the 400-meter dash in 60.48 seconds, so if she now divided that time into 8 equal time segments we have:

t = 60.48 s

By dividing the above equation into 8:

t = \frac{60.48 s}{8} = 7.56 s

Hence, she would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.

I hope it helps you!
