hahah idont know
Step-by-step explanation:
8293894=2893849222
A=adult
c=children
total lumber=30
total number=adults+children
a+c=30
total cost=50
total cost=acost+ccost
acost=a times cost per adult=a times 3=3a
ccost=c times cost per child=c tiems 1=1c=c
total cost=3a+c
50=3a+c
equiaotn are
a+c=30
3a+c=50
multiplyu first by -1 and add
3a-a+c-c=50-30
2a=20
a=10
sub
10+c=30
c=20
answer is A
Answer:
B. It has four right angles.
E. opposites side are parallel.
F. Diagonal are congruent.
Answer:
y-intercept: (0, 4)
x-intercept: (20, 0)
Step-by-step explanation:
y-intercept: The y-intercept of a graph is the point where the graph crosses the y -axis. That means, the point in which x = 0.
To find it, we can substitute x by 0 and find y.
x + 5y = 20
0 + 5y = 20
5y = 20
y = 20/5
y = 4
y-intercept: (0, 4)
x-intercept: The x-intercept of a graph is the point where the graph crosses the x-axis. That means the point in which y = 0.
To find it, we can substitute y by 0 and find x.
x + 5y = 20
x + 5*0 = 20
x = 20
x-intercept: (20, 0)
Finally, the graph of the equation is:
