2x+2 - -1x+4 ≤ -18
2x - 1x = 1x, and 2 + 4 = 6



1x + 6 ≤ 18.

6 - 6 = 0, 18 - 6 = 12

Therefore your answer is,

x <span>≤ 12</span>

You posted twice.

I already answered

2(x + 1) – (–x + 5) ≤ –18

2x + 2 + x - 5 <= -18

3x - 3 <= -18

3x <= -18 + 3

3x <= -15

  x <= -15/3

  x <= -5

Answer:

<u>Congruent pairs of triangles:</u>

ΔABD ≅ ΔDCB

  • AB≅CD - given
  • ∠ABD ≅ ∠CDB - given
  • BD≅DB - common side
  • SAS - two sides and the included angle

ΔABD ≅ ΔEFD - SAS

  • AB≅EF - given
  • ∠ABD ≅ ∠EFD - given
  • ∠ADB ≅ ∠EDF - vertical angles
  • AAS - two angles and non-included side

<u>By using the above two we can state that:</u>

ΔBDC ≅ ΔDFE - by ASA or SSS

because

  • BD ≅ DF (corresponding parts)  
  • AD ≅ BC  (corresponding parts)
  • AD ≅ ED  (corresponding parts)
  • and  therefore BC ≅ ED

<u>We can't prove that:</u>

  • ΔAGD is congruent with any of the others as not enough information

There is one side and one angle and we can' t get two angles or two sides with included angle. Maximum we can get is SSA which doesn't guarantee the congruence.

You are filling baskets using 18 green eggs, 36 red eggs and 54 blue eggs. What is the greatest number of baskets that you can f
Papessa [141]

Answer: 18 baskets

Explanation:

Let n = number of baskets that can be filled so that the baskets are identical and there are no eggs left over

Each color of eggs divisible by n must be equal to each other

18 green eggs, 36 red eggs and 54 blue eggs

18/n = 36/n = 54/n

Using logic and plug in method

All of them are divisible by 2, 3, 6, 9 and 18

The greatest is 18.

18 is therefore the greatest number of baskets that you can fill so that the baskets are identical and there are no eggs left over.

Another method is to use HCF among the 18 green eggs, 36 red eggs and 54 blue eggs.

This means that each basket will contain 1 green egg, 2 red eggs and 3 blue eggs.
