i dont understan the method you gave me can youbplease ask again showing a different method
Answer:
x = 0, y = 2
Step-by-step explanation:
- solve the equation for x
3x + 3(x + 2) = 6
2. Substitute the given value of x into the simplest equation y= x + 2
y = 0 + 2
3. Solve the equation for y
y= 2
4. The possible solution of the system is the ordered pair ( x, y)
( x, y) = ( 0, 2)
Answer:
x= (2/5)-(2y/5) (Im not sure if this is what you need but this is the answer simplified)
Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
If your teacher taught rise over run, then for the graphs:
y=-1/2x+1
start at y intercept of 1, then down 1, right 2 all the way, same for the other side but reversed.
y= 1/3+6
start at y intercept of 6, then up 1, right 3 all the way, same for the other side but reversed.
One solution: (-6,4)
Answer:
The sum of 1.8 and 1.56 is 3.36 according to the model
Sum of decimals
Given the expression 1.8 + 1.56
Using the partial sum method
1.8 + 1.56 = (1.0 + 0.8) + (1.0+0.56)
Regroup as whole and decimal number
1.8 + 1.56 = (1.0 + 1.0) + (0.8 +0.56)
1.8 + 1.56 = 2.0 + 1.36
1.8 + 1.56 = 3.36
Hence the sum of 1.8 and 1.56 is 3.36 according to the model
