Answer:
x = 25
scalene, acute
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
[tex]\implies (2x+11)+(3x-7)+(2x+1)=180[/tex]
[tex]\implies 2x+11+3x-7+2x+1=180[/tex]
Collect like terms:
[tex]\implies 2x+3x+2x+1+11-7=180[/tex]
Combine like terms:
[tex]\implies 7x+5=180[/tex]
Subtract 5 from both sides:
[tex]\implies 7x=175[/tex]
Divide both sides by 7:
[tex]\implies x=25[/tex]
Substituting found value of [tex]x[/tex] into the three angle expressions:
∠A = (2 x 25) + 11 = 61°
∠B = (3 x 25) - 7 = 68°
∠C = (2 x 25) + 1 = 51°
This is a scalene triangle as it has three different angles and three different side lengths (non-congruent).
It is also an acute triangle as all interior angles are less than 90°

There are a total of 114 oak and pine trees on a piece of land. There are 26 fewer oak trees than pine trees. There is a regulation that the number of oak trees on this piece of land cannot exceed one-third of the total number of trees. Find how many oak and pine trees are on this piece of land and determine whether the solution is viable or nonviable.
A: There are 36 oak trees and 78 pine trees. The solution is nonviable.
B: There are 44 oak trees and 70 pine trees. The solution is viable.
C: There are 44 oak trees and 70 pine trees. The solution is nonviable.
D: There are 36 oak trees and 78 pine trees. The solution is viable.
Answers
Answer: C) 44 Oak trees and 70 Pine trees
Step-by-step explanation:
Oak : o
Pine : p
Based on the info given,
o + p = 114
p = o + 26
You then have to substitute the P value into the original equation:
o + (o + 26) = 114 (remove the parenthesis here and solve)
o + o + 26 = 114
2o + 26 = 114
2o = 88
o = 44
There are 44 Oak trees

Select all the equations that are equivalent to 1/2(4+8x)=17.
1. 2+4x=8.5
2. 4x=15
3. 4+8x=8.5
4. 4+8x=34
5. 2=17-8x
Answers
Answer:
4x=15
Step-by-step explanation:
1/2(4+8x)=17. You divide everything inside the parentheses in half. So the new equation is 2+4x=17. You could combine like factors. So minus the two from the 17 to get 4x by itself. Now you have 4x=15

Answer:
x= 55
Step-by-step explanation:
Before we begin, the question tells us that angle JKL is a right angle. A right angle means the angle is 90 degrees. It tells us that one of the angle is 35 degrees and another is x. Since they make up a right angle, 35 plus x should equal to 90. To find x, subtract 35 from 90 and you get 55.

Select all values that are part of the domain of the function below. You must select all correct answers. PLEASE HELP!!!!!!!!!!!!!
Answers
Answer:
-6, -4, -2, 1, 4
Step-by-step explanation:
Domain is a word that refers to the first coordinate of points on the graph (the x coordinates).
Tip: to remember which is domain and which is range - (domain, range) alphabetical order!
It may help to think of sliding the points vertically (up or down) until they hit the x-axis. Examples: slide (-6, 2) down until it sits on the x-axis, (-4, 0) is alread on the x-axis, slide (-2, 4) down to the x-axis, etc.. Now look at where the points are sitting on the x-axis and write down their first coordinates: -6, -4, -2, 1, 4.
If you were asked about the range, you'd slide the points horizontally (right or left) until they sit on the y-axis.

There are 80 girls and 70 boys in the sixth grade. Of these students, 11 girls and 7 boys are left handed. What percentage of the sixth graders are left handed?
Answers
Answer:
12% of the sixth graders are left handed.
Step-by-step explanation:
There are 150 students in total. Out of those 150, 18 are left handed.
Step 1: We make the assumption that 150 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100% = 150
Step 4: In the same vein, x% = 18.
Step 5: This gives us a pair of simple equations:
100%=150(1)
x%=18(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 150/18
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 18/150
x = 12%
Therefore, 18 is 12% of 150 :)
