Y= 2.50 + 1.95( x)
27.46 = 2.50 + 1.95(x)
+2.50 -2.50
29.96 = 1.95(x)
/ 1.95 / 1 .95
x = 15.4 Miles total
Answer:
the price now is 100-35=65% of the initial price p
65p/100=78
65p=78*100
p=7800/65
p=120 ( the phone before the discounted price )
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let shakes be s and hamburgers be h. Then the total cost equation would be
2s + 3h = 17
The next equation in our system will be
3s + 4h = 24
You can solve this by either substitution or elimination. I'm going with substitution because it's easier in this platform to do so. I'm going to solve the second equation for h.
4h = 24 - 3s and
h = 6 - .75s
Now we will sub that into the first equation to get
2s + 3(6 - .75s) = 17 and
2s + 18 - 2.25s = 17 and
-.25s = -1 and
s = 4
That means that shakes cost $4 each. Now plug in 4 for s and solve for h:
h = 6 - .75(4) and
h = 6 - 3 so
h = 3 so hamburgers cost $3 each.
The decimal value 8.34 written as a ratio of a/b is 417/50
<h3>Conversion of decimal to fraction</h3>

-- There are 12 total bottles in the box. 8 of them are grey.
-- The probability of getting a grey bottle on the first draw is 8/12 .
-- Now there are 11 bottles left in the box, and 7 of them are grey
-- The probability of getting a grey bottle on the second draw is 7/11 .
-- The probability of both events happening is
(8/12) · (7/11) = 56/132 = 14/33 = about 42.4% (rounded)
