Option A is true because the sum of angles in a triangle is 180, so we can rule that one out immediately.

We can solve for x for the other 3 options by setting up this equation:

7x+2 + 4x+7 + 8x = 180 | Simplify

19x + 9 = 180 | Subtract 9

19x = 171 | Divide by 19
x=9

Now we can substitute x into all the values:
<J = 7x+2 = 65
<L = 4x+7 = 43
<K = 8x = 72


Looking at the options again, we can see that A, B, and D are true, leaving C to be false.

Farmer brown likes to grow his crops in equal amounts if the carrot seeds come in packs of 80 the zunchie come in packs of 40 an
solniwko [45]

Given,

The carrot comes in pack of 80

Zunchie comes in the pack of 40

The paper comes in the pack of 50.

To find,

The fewest number of each kind of seed that farmer brown will buy.

Solution,

To find least no of each kind, we must take the LCM of the above numbers such that,

The prime factors of the given numbers are :

80 = 2 × 2 × 2 × 2 × 5

40 = 2 × 2 × 2 × 5

50 = 2 × 5 × 5

LCM of 80,40 and 50 = 2 × 2 × 2 × 2 × 5 × 5

= 400

He should buy,

400/80 = 5 carrot seeds

400/40 = 10 zunchie seeds

400/50 = 8 papper seeds.

ololo11 [35]

Answer:

200,000

Step-by-step explanation

10 x 2 is 10

So (8x100)x(2.5x100) is 200,000

8x100=800

2.5x100=250

800x250=200,000
