To solve the two equations simultaneously using the substitution method we need to rearrange one of the equation to make either

or

the subject.
We can try in turn rearranging both equations and see which unknown term would have been easier to solve first
Equation

Making

the subject

, dividing each term by 2

⇒ (Option 1)
Making

the subject

, multiply each term by 8 gives

⇒ (Option 2)
Equation

Making

the subject

, divide each term by 3

⇒ (Option 3)
Making

the subject

, divide each term by 8

⇒ (Option 4)
From all the possibilities of rearranged term, the most efficient option would have been the first option, from equation

with

as the subject,
Answer:The number of words that she would still have to type to finish her essay is 1000
Step-by-step explanation:
Karen is typing a 4,000 word essay. She can type at about 30 words per minute. This means that if her rate remains constant, the total number of minutes that it will take her to finish would be
4000/30 = 133.33 minutes.
If she types for 45 minutes on Monday, it means that the total number of words that she typed on Monday would be
45 × 30 = 1350 words
If she types for 55 minutes on Tuesday, it means that the total number of words that she typed on Tuesday would be
55 × 30 = 1650 words
Total number of words typed on Monday and Tuesday would be
1350 + 1650 = 3000 words
The number of words that she would still have to type to finish her essay would be
4000 - 3000 = 1000 words
I think the answer is 2/15
I am guessing you have to rotate it 180 degrees and see if it fits in the area in which it’s supposed to fit it’s there another part to the question?
Note the order of the letters:
A C E G
M N P R
You read it like this:
A ≅ M
C ≅ N
CE ≅ NP
AG ≅ MR
... and so on
In the following choices:
CE ≅ NP is the true statement
