Answer:
(1, 4)
Step-by-step explanation:
subsitute y=x+3 into the 2nd equation, which you will get 7x-(x+3)=3
get rid of the (), which you will get 7x-x-3=3
combine like terms and get 6x-3=3
move 3 to the other side and divide both sides by 6 and get x=1
use the first equation y=x+3 and subsitude 1 for x and get y=1+3
y=4

Given:
Consider the below figure attached with this question.
Perimeter of triangle ABC is 13 cm.
Triangle ABC is dilated to create the triangle A'B'C'.
To find:
The perimeter of triangle A'B'C'.
Solution:
We know that, dilated figures are similar.
[tex]\text{Scale factor}=\dfrac{\text{Side of image}}{\text{Corresponding side of preimage}}[/tex]
[tex]\text{Scale factor}=\dfrac{OB'}{OB}[/tex]
[tex]\text{Scale factor}=\dfrac{5+15}{5}[/tex]
[tex]\text{Scale factor}=\dfrac{20}{5}[/tex]
[tex]\text{Scale factor}=4[/tex]
Perimeters of similar figure is proportional to the corresponding sides of that figure or equal to the scale factor.
[tex]\dfrac{\text{Perimeter of }\Delta A'B'C'}{\text{Perimeter of }\Delta ABC}=\text{Scale factor}[/tex]
[tex]\dfrac{\text{Perimeter of }\Delta A'B'C'}{13}=4[/tex]
Multiply both sides by 13.
[tex]\text{Perimeter of }\Delta A'B'C'=13\times 4[/tex]
[tex]\text{Perimeter of }\Delta A'B'C'=52[/tex]
Therefore, the perimeter of triangle A'B'C' is 52 cm.

The calculation is:
endamount - startamount divided by number of days.
(237-27) / 14 = 15
Answer:
237 - 27 = 210 (she already had 27 to start, so subtract that from the total)
210 ÷ 14 = 15 (divide by 14 because there are 14 days in two weeks)
so she bought 15 stickers each day

If you draw a card with a value of four or less from a standard deck of cards, I will pay you $162. If not, you pay me $45. (Aces are considered the highest card in the deck.) Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.
Answer:
the expected value of the proposition is 2.77
Step-by-step explanation:
The computation of the expected value of the proposition
= 162p - 45(1 - p)
= 162 × 12 ÷ 52 - 45 × (1 - 12 ÷ 52)
= 2.77
Hence, the expected value of the proposition is 2.77
So we simply do the above calculation so that the expected value could come
The median number of cars sold by 11 sales representatives in a certain month is 6. The range of number of cars
sold by those sales representatives that month is 4.
Determine if the following statement is true, is false, or does not contain enough information.
The fewest cars sold could be 0.

Answer:
False
Step-by-step explanation:
Khan Academy
The given statement is False.
What is median?
'In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution.'
According to the given problem,
Median = 6
Total count = 11
Range = 0
Now, range is the difference between the highest value and the lowest value.
Since, the median is 6, the highest number must be greater than 6. This would not have been possible if the lowest value was 0. If the lowest count had been 0, then the highest count had to be 4.
Hence, we can conclude, the fewest cars sold cannot be 0.

Reaner Recycling collected 7/4 ton of aluminum last Saturday. If 7/8 ton of aluminum can be shredded each day, how many days will it take to process what was collected on Saturday?
help me please it is hard
Answer:
2 days
Step-by-step explanation:
You would have to change 7/4 to have the same common denominator as 7/8, which is 8. 7/4 is equal to 14/8, or 1 6/8. Then you would subtract 1 6/8 by 7/8. What would be left would be 7/8. And of course, 7/8 minus 7/8 would be 0.

What is the equation of a parallel line to y = -5x + 2 that passes through the point (-1, 4)?
Answer:
The equation of the Parallel line passes through the point (-1,4) is
y = -5 x -1
Step-by-step explanation:
Explanation:-
Given the equation of the line y = -5 x + 2
Given point (-1 , 4 )
The equation of the parallel line of a given line is 5x + y +k=0 ...(i)
The equation (i) passes through the point (-1,4)
5(-1)+4+k=0
-5 +4 +k =0
-1 + k = 0
k = 1

What is the product of the radical expression?
(7- sqrt7)(-6 + sqrt7)
Given:
The expression is
[tex](7-\sqrt{7})(-6+\sqrt{7})[/tex]
To find:
The product of the radical expression.
Solution:
We have,
[tex](7-\sqrt{7})(-6+\sqrt{7})[/tex]
Using distributive propertry, we get
