Answer:
--- the equation of SaveMore company
Step-by-step explanation:
Given
SaveMore
Required
Determine the equation
Let
So, we have:
The equation for the second company is not given. So, the (b) part cannot be correctly answered.
A general solution to the (b) part is:
Assume the equation is:
Next, we equate both
i.e.
This gives:
Collect like terms
Divide by 0.2
<em>Hence, the charges will be the same after 30 texts</em>
Answer:
The larger number is 60
The smaller number is 14
Explanation:
Assume that the larger number is x and that the smaller number id y.
We are given that:
1- The sum of the two numbers is 74. This means that:
x + y = 74
This equation can be rewritten as:
x = 74 - y .............> I
2- Four times the smaller number (4y) subtracted from the larger number (x), the result would be 4. This means that:
x - 4y = 4 ..............> II
Substitute with I in II and solve for y as follows:
x - 4y = 4
74 - y - 4y = 4
74 - 5y = 4
5y = 70
y = 70/5
y = 14
Substitute with the value of y in equation I to get x as follows:
x = 74 - y
x = 74 - 14
x = 60
Hope this helps :)
Answer:
y = 16
x = 2
Step-by-step explanation:
y = 8x
y = 4x + 8
then, by substitution:
8x = 4x + 8
8x - 4x = 8
4x = 8
x = 8/4
x = 2
y = 8x
y = 8*2
y = 16
Check:
y = 4x + 8
y = 4*2 + 8
16 = 8 + 8
Answer:
its C)11,460
Step-by-step explanation:
you have to multiply 12,000 by the tax rate which is 960.So then you add them up and its 12,960 plus the 500 of the fees which is 13,460. Finally you subtract 13,460 by 2,000 and its C)11,460
