Answer:
TU = 12
Step-by-step explanation:
Given
TU = x − 1
SU = 3x − 7
ST = x + 7
TU = ?
Then we can say that
SU = ST + TU
⇒ 3x − 7 = (x + 7) + (x − 1)
⇒ 3x − 7 = 2x + 6
⇒ x = 13
Finally, we get
TU = x − 1
⇒ TU = 13 - 1
⇒ TU = 12
Therefore,
ST = x + 7 = 13 + 7 = 20
SU = 3x − 7 = 3*(13) - 7 = 32
1 box = 100 buttons
10 boxes = 1000 buttons
5 boxes = 500 buttons
----------------------------------------
15 boxes = 1500 Buttons
Answer:
well there is a formula for this type of problem...
but the given points are exactly 14 units apart...
dividing by (4+3)= 7, so the ration is 14/7 = 2
therefore we need the point that is 2*4=8 from one end
and 2*3 = 6 from the other end, so that their distance is 8+6=14
that must be (-7,-1)
Step-by-step explanation:
First let's calculate the final price at the electronic store.
499.99*(1+0.05)≈524.99
Now let's calculate the final price online
(549.99+22.95)*(1-0.1)≈515.65
If we compare the two we can see that the online price is cheaper at around 515.65 dollar therefore the second choice is correct.
I hope this helped if you have any questions please ask!
