Answer:
C=30
Step-by-step explanation:
Supposing that we have the lines
x+2=10y
and
3x+6=Yc.
Note that dividing by 3 the second line can be rewritten as
x + 2= Y c/3.
Remember that a line is written as
, in our case, both lines have
and
. Therefore, in orther that the two lines are equal, we need that
, hence 
Answer:
$1,300
Step-by-step explanation:
commission on the first $10,000
= 4/100 * 10000
= $400
remaining amount
= $28,000 - $10,000
= $18,000
commission on remaining $18,000
= 5/100 * 18000
= $900
total commission
= $400 + $900
= $1,300
Answer:
The angles are vertical
Step-by-step explanation:
x+42+2x+1=180
put the like terms together i.e 2x+x+42+1=180
you get: 3x+43=180
Take 43 to th other side of 180 i.e 3x=180-43 i.e (180-43=137)
You get 3x=137
Divide both sides by 3
you get x=45.666666666667(Round off to get 45.67)
Substitute the value of x to the angles
x+42(45.67+42=87.67)
2x+1(2(45.67)+1=92.34
Add 87.67+92.34=180
THis shows that the angles are vertical
Answer:
Adult= $24
child= $21
Step-by-step explanation:
first let's create an equation for each one.
Day 1: 7x+8y=168
day 2: 14x+13y=294
By doing so we can either graph and get the points for x,y or we can substitute each (x=0) (y=0) and solve manually.
x-int.= (24,0)
y-int.=(0,21)
