Answer:
is the required equation.
The Per sq ft of sheet costs $ 27.31.
Step-by-step explanation:
The total amount of sheet purchased = 8.8 sq. ft
The amount of sheet used = 2. 1 sq ft.
The worth of remaining sheet = $183
Let us assume the cost per sq ft of sheet = $x
Now, the remaining sheet =
Amount of total sheet purchased- Amount of sheet used
= 8.8 sq. ft - 2. 1 sq ft. = 6. 7 sq. ft
So, the worth of the remaining sheet 6.7 sq ft is $183.
⇒ Worth of 1 sq ft of sheet = $183 /6.7 sq ft
or,
or x = $27.31
Hence, the Per sq ft of sheet costs $ 27.31.
Not completely sure how to answer your question but all 20 questions where worth 5 points each which she would have gotten a 100 if she got all right but she got 15 which her score would be 75. I think in a ratio of correct to incorrect would be 75:100 , I'm not sure completely.
Answer:
2x + 3y = 12
Step-by-step explanation:
Standard form is Ax + By = C, A, B and C must be intergers, cannot be fractions or decimals
y = -2/3x + 4 First we want to get rid of the fractions. There is only one, so if we multiply both sides by 3 that should do it.
3y = -2x + 12 Now make the constant be on one side by itself
2x + 3y = 12
Multiply both by -1: 113.75-112=1.75
multiply answer by -1: -1.75
Answer:
13/3 -3i
Step-by-step explanation:
(3i-2/3)-(6i-5)
Distribute the minus sign
(3i-2/3)-6i+5
Combine like term
-2/3 +5 +3i - 6i
-2/3 +15/3 -3i
13/3 -3i
This is standard form
