Answer:
x=0
y= -1
Step-by-step explanation:
x−2y=2 - eq 1
3x+2y=−2 - eq 2
x−2y=2
(3x+2y)+(x−2y)=−2+2
x−2y=2
3x+2y+x−2y=0
x=0
y= -1
Answer: 23
Step-by-step explanation:
The equation for the first option is Y=10x + 200
The equation for the second option is Y=30x + 100
X = one month
To find when they would be the same about you have to set the equations equal to each other
10x + 200 = 30x + 100
-10x -100 -10x -100
100= 20x
5 = x
After five months she would save the same amount. To find how much is saved you have to plug in 5 for x in one of the equations. You can always double-check 5 by plugging it in both equations and making sure you get the same answer
Y= 10(5) + 200 = 250
Y= 30(5) + 100 = 250
She would have saved $250 after five months by using either method
Answer: 30.1
Step-by-step explanation:
Cups of raisins mixed= 10.33
Cups of pretzels mixed= 12.25
Cups of chocolate mixed= 7.50
When each ingredients is rounded to the nearest tenths, it will be:
Cups of raisins mixed= 10.3
Cups of pretzels mixed= 12.3
Cups of chocolate mixed= 7.5
Total trail mixed by John= 10.3 + 12.3 + 7.5 = 30.1
30.1 cups was mixed together by John.
Answer:
44 millimeters
Step-by-step explanation:
Because 99 meters divided by 9 = 11.
So, I multiplied 4 x 11 to get 44 millimeters.
