Answer:
Speedy Taxis
Step-by-step explanation:
I solved this by using a graphing calculator. Speedy Taxis shows the least cost for x=30.
__
You can figure the cost of each for x=30
1.5(30) = 45
1.1(30)+11.5 = 33+11.5 = 44.5 . . . . . lowest cost
1.25(30)+8 = 37.5+8 = 45.5
Speedy Taxis is the cheapest for a trip of 30 miles.
8x10^5 = 800,000
times 800,000 by 0.5 (or just half it) would equal 400,000, which is translated to 4x10^5
Answer:
The amount of floor Mrs.Stewart needs for
cups of shortening
cups.
Step-by-step explanation:
Mrs.Stewart pie dough needs
cups of shortening for
cups of flour.
Now we assume that the shortening needed for
cups of flour is
cups.
Accordingly we can arrange the ratios.

Plugging the value of
as it is number of cups of shortening Mrs.Stewart have used.
And multiplying both sides with
,we have
Number of cups of flour (x) 
So (x) 
The amount of floor Mrs.Stewart needed for
cups of shortening =
.
Answer:
x<-3
Step-by-step explanation:
First we multiply by 4. We will get: -16x-12>36
Then we add 12 to both sides. We'll get -16x>48
Then we divide by -16. 48 divided by -16 is -3.
x<-3.
