Answer:
y = x - 2
Step-by-step explanation:
slope intercept form
y = mx + b
m = rise / run = -5 / 6
b = -2
y = x - 2
Answer:
See below.
Step-by-step explanation:
The error is she reversed the direction of the inequality. The only time you do that is when multiplying an inequality by a <u>negative</u> number.
She should have done:
Answer:
Step-by-step explanation:
126 mi/h = (126 mi)/(1 h)·(5280 ft)/(1 mi)·(1 h)/(3600 s) = (126·5280/3600) ft/s
126 mi/h = 184.8 ft/s = 924/5 ft/s
__
In 2 seconds, the parachutist falls ...
(184.8 ft/s)·(2 s) = 369.6 ft
Answer:
Pounds of apple used = 10,078.20
Pounds of taffy = 144.80
Step-by-step explanation:
Assume :
x = pound of taffy mixture
y = pounds of apple mixture
Total :
x + y = 10,223 - - - (1)
Proportion of apple to taffy
x / y = 1 / 69.6
Cross multiply :
y = 69.6x
(1) becomes :
x + 69.6x = 10223
70.6x = 10223
x = 10223 / 70.6
x = 144.80169
Put x = 144.80169 in
y = 10223 - x
y = 10223 - 144.80169
y = 10078.19831
Pounds of apple used = 10,078.20
Pounds of taffy = 144.80
As per the problem
Erika drove 280 miles in 5.5 hours.
She averaged 40 miles per hour driving through towns and cities .
She averaged 55 miles per hour driving on the highway.
Let Erika drive on high for "t" hours on highway.
Then driving time other than highway
As we know that
Hence for 4 hours Erika drove on the highway.
