<span>1. Solve the system by substitution -2x+y=-11, 3x-4y=11.
</span>-2x+y=-11<span>
y = 2x-11
</span><span>3x-4y=11
</span>3x-4(2x-11)=11
3x -8x + 44 = 11
-5x = -33
<span>x =33/5
y = 11/5
</span><span>2. Solve the system using elimination- 2x+6y=-12, 5x-5y=10.
</span><span>(-2x+6y=-12)5
</span>-10x + 30y = -60
<span>(5x-5y=10)2
</span>10x - 10y = 20
Adding the two equations,
<span>-10x + 30y = -60
</span><span>10x - 10y = 20
</span>
20y = -40
y = -2
x = 0
<span>3. What is the solution of the following system?-3x-2y=-12, 9x+6y=-9.
</span><span>-3x-2y=-12
</span>y = -3/2 x + 6
<span>9x+6y=-9
</span>y = -3/2 x - 3/2
Since the slopes are equal then they are parallel lines so they never meet at one point.
Answer:
The square root of 24
Step-by-step explanation:
The square root of 24 is about 4.899 which is greater than 4.256.
Answer:
$41.9
Step-by-step explanation:
divide $62.85 and get 20.95 which is 1/3 of it so then you just subtract $20.95 from $62.85 and get 41.9
How much more does the hamster weighs than the mouse is 300 pounds.
Since we have a pet hamster and a pet mouse. We know that the hamster weighs 416 of a pound and the mouse weighs 116 of a pound.
To know how much more the hamster weighs more than the mouse, we take the difference between the weight of the hamster and the weight of the mouse.
Since the weight of the hamster = 416 pounds and the weight of the mouse equals 116 pounds.
<h3>The difference in weight</h3>
The difference in the weight d = weight of hamster - weight of mouse
= 416 pounds - 116 pounds
= 300 pounds.
So, how much more does the hamster weighs than the mouse is 300 pounds.
