Answer:
82
Step-by-step explanation:
Angle J is 118, M is 90, and L is 70.
160 rabbits. 120/30=4
This means you will DOUBLE the 10 rabbits 4 times.
10+10=20
20+20=40
40+40=80
80+80=160
Explanation:
The starting system is:
{
0.4
x
−
0.1
y
=
2
0.2
x
+
0.5
y
=
1
If we multiply the second equation by
−
2
the coefficients of
x
will be opposite numbers:
{
0.4
x
−
0.1
y
=
2
−
0.4
x
−
y
=
−
2
Now we can add both sides of the equations to get an euation of 1 variable:
−
1.1
y
=
0
y
=
0
Now we have to substitute the calculated value of
y
to calculate
x
:
0.4
x
=
2
x
=
2
0.4
=
20
4
=
5
Answer:
The solution of this systemm is:
{
x= 5
Y=0

Answer:
4x - 8
Step-by-step explanation:
... ∠RST = ∠RSQ + ∠QST
Since SQ bisects ∠RST, that means ...
... ∠RSQ = ∠QST
Using this fact in the first equation, we have
... ∠RST = ∠RSQ + ∠RSQ = 2×∠RSQ
Using the given expression for ∠RSQ, we have
... ∠RST = 2×(2x-4) = 4x - 8
