Answer: First.
Step-by-step explanation:
Let's find the speed of the first airplane:
2800 ÷ 5 = 560 (miles per hour)
Let's find the speed of the second plane:
3885 ÷ 7 = 555 (miles per hour)
Thus, the first plane flies faster than the second.
Answer:
Option D In step 4 Keith should have subtracted 5 from each side
Step-by-step explanation:
step 1
we have
f(x)=7x+5 -----> given
step 1 is correct
step 2
Change f(x) to y
y=7x+5
so
step 2 is correct
step 3
Exchange x for y and y for x
x=7y+5
so
step 3 is correct
step 4
Subtract 5 each side
x-5=7y+5-5
x-5=7y
<u><em>step 4 is not correct</em></u>
step 5
Divide by 7 each side
(x-5)/7=y
step 6
Change y to g(x)
(x-5)/7=g(x)
step 7
switch sides of the equation
g(x)=(x-5)/7
therefore
In step 4 Keith should have subtracted 5 from each side
Rounded to the nearest hundredth, numbers look like this:
So, our number lies between 0.62 and 0.63. We have to check which of the two is closer. To measure the distance between numbers, we use the absolute value of the difference:
Since 
, we deduce that 0.63 is closer to 0.6288 than 0.62, and thus it's a better approximation.
(8x2)3 if that is meaning 8 times 2??
can be simplified to 48
Answer:
C I think
Step-by-step explanation:
It's kinda hard to explain... I'd need more time to be sure, sorry. When's this due? Can you send a bigger picture and can I have about 10 more mins to solve, give or take?
