The partial products would be 10 multiply 40, 10 multiply 3, 7 multiply 40, and 7 multiply 3.
Answer: x = 0
y = 2
z = -1
Step-by-step explanation:
The system of equations are
x+y+z=1 - - - - - - - - - - 1
-2x+4y+6z=2 - - - - - - - - - 2
-x+3y-5z=11 - - - - - - - - - 3
Step 1
We would eliminate x by adding equation 1 to equation 3. It becomes
4y -4z = 12 - - - - - - - - - 4
Step 2
We would multiply equation 1 by 2. It becomes
2x + 2y + 2z = 2 - - - - - - - - - 5
We would add equation 2 and equation 5. It becomes
6y + 8z = 4 - - - - - - - - - 6
Step 3
We would multiply equation 4 by 6 and equation 6 by 4. It becomes
24y - 24z = 72 - - - - - - - - 7
24y + 32z = 16 - - - - - - - - 8
We would subtract equation 8 from equation 7. It becomes
-56z = 56
z = -56/56 = -1
Substituting z = -1 into 7, it becomes
24y - 24×-1 = 72
24y + 24 = 72
24y = 72 - 24 = 48
y = 48/24 = 2
Substituting y = 2 and z = -1 into equation 1, it becomes
x + 2 - 1 = 1
x = 1 - 1 = 0
Answer:
3⅘ lb
Step-by-step explanation:
(a) <em>Amount eaten</em>
Eaten = 10⅖ + 10⅘
Think of pounds as pies. Each pie has 5 slices.
10⅖ pies = 10 pies + 2 slices = 50 slices + 2 slices = 52 slices
10⅘ pies = 10 pies + 2 slices = 50 slices + 4 slices = 54 slices
Eaten = 52 slices + 54 slices = 106 slices
(b) <em>Amount remaining</em>
Remaining = Original – Eaten
Original = 25 pies = 125 slices
Eaten = 106 slices
Remaining = 125 slices -106 slices
Remaining = 19 slices Convert slices to pies
Remaining = 15 slices + 4 slices
Remaining = 3 pies + 4 slices Convert to mixed fraction
Remaining = 3⅘ pies Convert pies to pounds
Remaining dog food = 3⅘ lb
Answer:
DE and BC
Step-by-step explanation:
Because the pieces of the two sides of the triangle would be proportional the line in the middle that has specified points will be parallel to the bottom line that was specified points. and because neither f or g were specified to be proportional they are irrelevant.

HAVE A GREAT DAY
Remember that the slope intercept formula is:
y = mx + b
m is the slope (
)
b is the y-intercept
In this case the slope is...
^^^This has a negative slope because the line is decreasing from left to right
The y-intercept is...
(0, -2)
so...
y = x - 2
Hope this helped!
