-2 + Y = 8
Y = 10
Plug in Y to the first equation, 10 + 4 = X
X = 14
The two numbers are (7+ sqrt(65))/2 and (7- sqrt(65))/2
(7+ sqrt(65))/2+ (7- sqrt(65))/2= 7
(7+ sqrt(65))/2* (7- sqrt(65))/2)= -4.
Hope this helps~
Answer:
Congruence between pentagons
Step-by-step explanation:
The relationship occurs because having two congruent Pentagons and generating a segment within them (or outside), congruence is extrapolated to the triangles generated within them. Thus, if there is congruence among the pentagons, it will exist between the formed triangles. In other words since the two pentagons are congruent, the corresponding angle pair is congruent. also the two corresponding side pairs are also congruent.
In the attached image for example, the ABCDE and KLMNO pentagons are congruent, so all of their internal division lines are also congruent (AC and KM)
Given:
x y
0 40
4 120
y = fixed amount + v(x)
y = 40 + v(0)
y = 40
y = 40 + v(x)
120 = 40 + v(4)
120 - 40 = v(4)
80 = v(4)
80/4 = v
20 = v
y = 40 + 20x
The fixed amount charged is 40.
The variable amount is 20 per day.
Answer: Chad has 11/ 12 paints altogether.
Step-by-step explanation:
Amount of yellow paint = 2/3
Amount of white paint = 1/4
total amount of white and yellow paint altogether
= 2/3 + 1/4
= 8+ 3/12
=11/12
