Answer:
they are both alike because you're dividing both equations by 2 . in both equations you're trying to get the variable by itself .
they are both different because both of the equations have a different x= . in equation 1 you subtract and in equation 2 you would add .
Step-by-step explanation:
For 2x+4=20 you would make +4 negative 4 to get the variable by itself .
then you'd subtract the numbers 20-4=16
then divide both sides by 2 2÷2 and 16÷2
x=8 is your answer
for 2x-4=20 you would make -4 and make it positive 4 to get the variable by itself
then you'd add the numbers 20+4
then divide both sides by 2 2÷2 and 24÷2
x=12
Since the question is using the baby as a reference for much the male and female eats. Treat baby as the variable or x
So 3x+2x+x=181.5lb
6x=181.5lb
x=30.25lb.
female lb.=2×30.25=60.5lb of bamboo
hopefully that helps.
A.) Your percent equation would be 250 x 0.12(or 12%)= 30
b.) Olaf would have 30 photos on his external hard drive.
Hope This Helps!

Answer:
The line does not intersect the curve
Step-by-step explanation:
Assuming that we are looking for the points of intersection of
and
We make y the subject in the second equation to get:
When we substitute into the first equation:
Let us expand to get:
We obtain the standard form
Divide through by 5
The discriminant is
Hence the quadratic equation has no real roots.
This means the line and point has no point of intersection.
Answer:
Cuadrilátero solo significa "cuatro lados" (quad significa cuatro, lateral significa lado). Un cuadrilátero tiene cuatro lados, es bidimensional (una forma plana), cerrado (las líneas se unen) y tiene lados rectos.
Un cuadrilátero es un polígono con cuatro aristas y cuatro vértices.
Step-by-step explanation:
