Answer:
The length of the blue-and-yellow macaw is 42 in
Step-by-step explanation:
Let
x ----> the length of the toucan in inches
y ----> the length of the blue-and-yellow macaw in inches
we know that
----> equation A
----> equation B
substitute equation B in equation A and solve for y
Multiply by 3 both sides to remove the fraction
Divide by 2 both sides
therefore
The length of the blue-and-yellow macaw is 42 in
This looks fun
ok so
we will use subsitution
xy=-10
divide both sides by x or y (I will choose y)
x=-10/y
sub -10/y fo x
(-10/y)^2+y^2=36
100/(y^2)+y^2=36
times both sides by y^2
100+y^4=36y^2
minus 36y^2 from both sides
y^4-36y^2+100=0
(y^2)^2-36(y^2)+100=0
quadratic formula
for
ax^2+bx+c=0
x=
x=
x=
sub
y=-10/x
y=
so x+y=
+
multiply first number by
and add them
x+y=
or
x+y=
or
Answer:
Add the repair cost and tax to get the total amount. Then multiply the total amount by 0.15 to find the gratuity.
Step-by-step explanation:
This is sample response
39/3 is 13
So to find out the total members is
13 x 5 = 65
The total members in the "conductors" club is
65 members.
