Answer:
6.50x + 5 = 21.25 is the answer
Step-by-step explanation:
x=2.5
The easiest way to calculate this, since you don't need to know what the discount is, if the decrease is 4% you still have 96%.
Multiply 29,000 x .96= $27,840.
If you do it the other way, .04 x 29000= 1160. Then subtract 29000-1160=27850.
Answer:
3x - (15 x 3) = 90
or
3x - 45 = 90
Explanation:
there are 3 boxes. We don't know how many are in them yet, so we write this as 3x. However, we know that we give away 15 to 3 different teachers. 15 x 3 = 45
Therefore the first part is 3x - 45
We also know that in the end we have 90 left.
So our final equation is:
3x - 45 = 90
Answer:
ok, I can help. Where's the math problem ?
Step-by-step explanation:
Answer: y-7 = 4(x+3), choice B
============================================
Point slope form is generally
y-y1 = m(x-x1)
we have m as the slope and (x1,y1) as the point this line goes through. In this case,
m = 4
(x1,y1) = (-3,7) so x1 = -3 and y1 = 7
So,
y-y1 = m(x-x1)
y - 7 = 4(x - (-3))
y - 7 = 4(x + 3)
which is why choice B is the answer
