Answer:
{x,y,z} = {-18,4,2}
Step-by-step explanation:
Solve equation [2] for the variable x
x = -10y + 2z + 18
Plug this in for variable x in equation [1]
(-10y+2z+18) + 9y + z = 20
- y + 3z = 2
Plug this in for variable x in equation [3]
3•(-10y+2z+18) + 27y + 2z = 58
- 3y + 8z = 4
Solve equation [1] for the variable y
y = 3z - 2
Plug this in for variable y in equation [3]
- 3•(3z-2) + 8z = 4
- z = -2
Solve equation [3] for the variable z
z = 2
By now we know this much :
x = -10y+2z+18
y = 3z-2
z = 2
Use the z value to solve for y
y = 3(2)-2 = 4
Use the y and z values to solve for x
x = -10(4)+2(2)+18 = -18

1/10 x 90 I think that's the answer
<span>To acquire knowledge, thought is a fundamental necessity
-It must be "thought about" before any new ideas can be formulated (e.g., a student who is learning English as a second language must be competent in his primary native language before he can "think" or understand new concepts in another language)
-Initial emergence of language and thought are separate from each other, until about the age of 3 when a transition takes place in the child from the external to the internal
-Children practice private speech (self-talk) to become more competent
---The use of private speech helps children to self-regulate through organizing, guiding, and controlling their behavior
---Private speech is responsible for all higher levels of mental functioning
Noam Chomsky
Language Acquisition
-Language learning is innate
-Chomsky believes that children are prewired to learn language and that infants have a language acquisition device (LAD) built-in neurologically so that they can intuitively understand grammar
-There is a critical period when children find it easy to learn language
Language development milestones: Infant (0-12 months)
-Early vocalizations are spontaneous sounds of cooing (vowels) or crying
-Then babbling sounds (phonemes) begin with sounds more like patterned speech with consonant-vowel strings ("da-da-da-da")</span>
