How you find 8 and 10

Mathematics
1 answer:
Fittoniya [83]3 years ago
8 0

Answer:

8. X = 10.5 and 19. X = 5

Step-by-step explanation:

8. You know that a triangle interior angles should add up to 180° so:

(10x - 11) + (3x - 2) + (3x + 1) = 180

180 = 16x - 12

168 = 16x

The you divide each side by 16:

168 ÷ 16 = 16x ÷ 16

X = 10.5

10. You know that a straight line equals 180° and interior angles add up to 180° so:

1st you do 180 - 151 = 29°

2nd (11x - 1) + (20x - 3) + (29) = 180

180 = 31x + 25

155 = 31x

The you divide each side by 31:

155 ÷ 31 = 31x ÷ 31

X = 5

Graph the following system of linear inequalities. Identify at least two points in the solution: y &lt; 5 - 2x | x + 5y &gt; -7
romanna [79]

Answer:

(1,2) and (2,-1)

Step-by-step explanation:

we have

y< 5-2x ----> inequality A

The solution of the inequality A is the shaded area below the dashed line y=5-2x

x+5y>-7 ---->inequality B

The solution of the inequality B is the shaded area above the dashed line x+5y=-7

The solution of the system of inequalities is the triangular shaded area between the two dashed lines

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area

Two points in the solution are(1,2) and (2,-1)see the attached figure
