Kyle bought himself a pair of shoes for 89.50 and he bought his nephew a pair for half the price of his shoes. If the sales tax
ycow [4]
Solution-

89.50/2 = 44.75

44.75 is the amount he spent to buy his nephew the pair of shoes.

Now, we are going to add the amount he spent for himself and his nephew together. 

89.50 + 44.75= 134.25

134.25 is the amount he spent in total, now we need to find the final amount with sales tax included.

We can do this by multiplying the total price by .075

134.25 * .075 = 10.07 (I rounded this to the nearest hundredths because we are dealing with money)

Now we need to add the two number together. 

134.25 + 10.07 = 144.32

Answer- 

The total amount Kyle spent is $144.32

BigorU [14]

Answer:

a)27-x

Step-by-step explanation:

when a boat travels in the same direction as the current is downstream-->speeds the boat. If the rate of the boat in still water is 27 mph and the rate of the current of a river is x mph, the rate of the boat when the boat is going downstream is 27+x

when a boat travels against the current is upstream-->slow down. If the rate of the boat in still water is 27 mph and the rate of the current of a river is x mph, the rate of the boat when the boat is going upstream is 27-x

A line with slope of -1/10 passes thorugh the point (1,8). What is its equation in point slope form?
Alisiya [41]

ABOUT POINT SLOPE FORM:

  • y - Y1 = m(x - X1)
  • m represents the slope
  • Y1 & X1 is a point
  • The form allows you to identify the slope & the point on the line

y - Y1 = m(x - X1)

y - 8 = -1/10(x - 1) -- IN POINT SLOPE FORM
