Answer:
124 degrees
Step-by-step explanation:
x=24 so if you plug in the value and solve it is 124 degrees
Paula's dog is 36 lbs
Use the equation 48=3x+x
Add like terms: 48=4x
Divide: 12=x (x=Carla's dog's weight)
Then Multiply x by 3 to get Paula's dog's weight and you get 36 lbs
6x y³ × 4x² y²
=
24 x¹+² y³+²
=
24x³ y⁵
Answer:
Step-by-step explanation:
take 45 degree as reference angle
use sin rule
sin 45=opposite/hypotenuse
1/=x/2
do cross multiplication
x= *
x=2
x=2/
x=
pythagoras theorem
a^2+b^2=c^2
( )^2+y^2=(2 )^2
2+y^2=8
y^2=8-2
y=
<em>Note: I am assuming your second equation is:</em>
<em>x = 2y - 1</em>

Answer:
The solution to the system of equations is:
Step-by-step explanation:
Given the system of equations
2x+y=3
x = 2y - 1
solving the system of equations using the elimination method
Arrange equation variables for elimination
Multiply x-2y=-1 by2: 2x-4y=-2
subtracting the equations
now solve -5y = -5 for y
Divide both sides by -5
Simplify
For 2x+y=3 plug in y=1
subtract 1 from both sides
Simplify
Divide both sides by 2
Simplify
Therefore, the solution to the system of equations is:
