Answer:
C 3 cm per present
Step-by-step explanation:
1 = 3cm
2 = 6cm
3 = 9cm
Answer:
x = 1, y = -1
Step-by-step explanation:
If we have the two equations:
and 
, we can look at which variable will be easiest to eliminate.
looks like it might be easy to get rid of, we just have to multiply by 2 and y is gone (as -6y + 6y = 0).
So let's multiply the equation by 2.
Now we can add these equations
------------------------
Dividing both sides by 5, we get 
.
Now we can substitute x into an equation to find y.
Hope this helped!
Let x be the number of gb used.
Question (1):
Runfast = 10 + 4x
<span>BA&D= 6 + 6x
Question (2):
</span> 10 + 4x = 6 + 6x
2x = 4
x = 2
Both companies will cost the same if you use 2 Gb of data.
BA&D will be cheaper if you use less than 2 Gb of data.
Runfast will be cheaper if you use more than 2 Gb of data.
Answer:
D
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers
12 = 2x + 4y , that is
2x + 4y = 12 ← is in standard form
9/10 - 11/12
Multiply both sides to find a common denominator in this case it’s 60
54/60 - 55/60
Then the answer would be -1/60
