Answer:
80°
Step-by-step explanation:
42° + 58° + x = 180° [Angle sum property of triangle]
=> 100 + x = 180
=> x = 180 - 100
=> <u>x = 80 (Ans)</u>
Given inequality:
To find:
Which values are solutions to the inequality.
Solution:
Substitute the values in the x place.
Option A: 48
6.9 ≤ 7
Therefore 48 is one solution of the inequality.
It is true.
Option B: -5
We cannot compare a complex number and a real number.
Therefore -5 is not a solution of the inequality.
it is not true.
Option C: 50
7.07 > 7
Therefore 50 is not a solution of the inequality.
It is not true.
Option D: 49
7 ≤ 7
Therefore 49 is one solution of the inequality.
It is true.
Option E: 44
6.6 ≤ 7
Therefore 44 is one solution of the inequality.
It is true.
Option F: 2401
49 > 7
Therefore 2401 is not a solution of the inequality.
It is not true.
Therefore 48, 49 and 44 are solutions to the inequality.
Answer:
bro i got you
answer: x=7
Step-by-step explanation:
3x = 4x-9
subtract 4x from each side
-x=-9
x=9
enjoy bro get that good grade
In triangle do pythogrean to find height 5 sq -3sq = 16 and sq rt of 16 is 4
So triangles are 1/2 bh 1/2 (3)4 = 6
One sale 5x5 one shape 5x4 one gape 3x5 plus two triangles
25+ 20+ 15 + 6+6= 72
A. p = 8n - 30
Each item n is $8.
Expenses totaling $30 are subtracted.
So if the profit (p) is $170.00,
170 = 8n - 30
Now you need to solve.
Add 30 to both sides.
200 = 8n
Divide both sides by 8.
25 = n
25 items were bought.
b. If 25 items were bought, but the expenses were instead $40, what would be the total profit?
p = 8(25) - 40
p = 200 - 40
p = 160
The profit decreased by 10.
