Because the triangles are congruent, their angles and sides are of equal degrees and length. Therefore you can set them equal to each other and solve. First, lets look at the angle because there is only 1 variable in it and so it is solvable. For the equation 20 = 3x - 8, x = 28/3. The second equation, 1/4x+y = 14.7 (which is found by setting the sides equal to each other), You can plug in 28/3 for x making the equation 28/12+y=14.7. Which makes y = 371/30.

It is giving you what the value of x is, -6.1.
Substitute
38.1 - 6.1

You divide 3 3/4 by 1 1/2
First turn the mixed numbers into improper fractions.
Multiply the whole number by the denominator then add the numerator. Keep the denominator the same.
3 3/4:
3 x 4 = 12
12+3
= 15/4
1 1/2 :
1 x 2= 2
2+1
= 3/2
now you're dividing 15/4 by 3/2
My teacher always taught me KFC:
Keep, change flip
Keep:
Keep the first fraction don't change it. 15/4 stays the same.
Change:
Change the division sign to multiplication.
Flip:
Flip the last fraction to its reciprocal.
In this case instead of it being 3/2, it will be 2/3
Next
Multiply straight across
15/4 x 2/3
15 x 2 = 30
4 x 3 = 12
30/12
Simplified would be 5/2 as an improper fraction
or
2 1/3 as a mixed number

b) 1,000 people
Step-by-step explanation:
To determine how many people will attend this year's fair, we can find the percent increase of people each year:
From year 1 to year 2, (10,365 - 9,278)/9,278 = 11.7% increase
From year 2 to year 3, (12,128 - 10,365)/10,365 = 17.0% increase
From year 3 to year 4, (13,304 - 12,128)/12,128 = 9.7% increase

The cost of a trail mix at the grocery store is normally $12 per pound but now the price has increased by 30%. What is the price per pound of trail mix now that the price has increased?
Answers
Answer:
15.6
Step-by-step explanation:
The price of trail mix has increased by $12 * 30/100 = $<<12*30/100=3.6>>3.6.
So the price per pound of trail mix now is $12 + $3.6 = $<<12+3.6=15.6>>15.6.
The required new price of the trail mix is $15.6 .
What is percentage?Percentage is a measurement to find value of given number out of hundred.
Given that,
The normal cost of trail mix at the grocery store = $12 per pound.
Als0, the price of the trail mix increased by 30%.
To find the price of trail mix after increasing the price,
Use percentage property,
Let the initial price was 100 %
So after increasing 30%, the new price becomes 130%.
The new price = 12 x 130% = 12 x 130 / 100 = 1560/100 = 15.6
The increased price of the trail mix is $15.6.

Which graph represents the inequality 2.5 is less than the product of −0.5 and a number?
Answers
Answer: The mathematical statement is given as
"2.5 greater than the product of -0.5 and a number"
Product means times
So, we have the following representation
"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 greater than -0.5 * a number
Let the number be x
So, we have
"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 greater than -0.5x
Greater than is represented by >
So, we have
"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 > -0.5x
Next, we plot the graph of the inequality expression
