Answer:
first one is 120cm
second one is 7.5 miles
Step-by-step explanation:
one book is 3.75
maximum books are 25
so 25×3.75 = 93.75
second question he crosses 0.63 to go for work
and 0.63 to go home so in one day he crosses 1.26 miles
in 6 days is (1.26×6) = 7.56
Answer:
x=4
Step-by-step explanation:
5x-7=13
5x=13+7
5x=20
x=20/5
x=4
First, determine what is 40% of $600. Multiple 40 (as a decimal) by 600.
0.4 x 600 = 240
Therefore, the discount is $240 off $600.
Subtract the two values to find price (before tax): 600 - 240 = 360
So the TV will cost $360 before tax.
The tax is 8.5%. Multiply 8.5 as a decimal by 360 to find the amount of tax added.
0.085 x 360 = 30.6
Add 30.6 and the price before tax to find the final price.
30.6 + 360 = 390.60
Therefore, the final price of the TV is $390.60
Answer:
A(x) = 6.2 - 0.005x
Step-by-step explanation:
If you think about it, either 0.5/0.005 needs to be equal to 0.5%
0.5 is the same as 1/2 and therefore it is the same as 50%
So it must be 0.005!
Tip: I always just divide by 100 to get the decimal, it is a nice, easy and quick method
Answer:
The correct answer is: 
Step-by-step explanation:
As stated in the question that x represents the number of minutes his <em>normal</em> commute takes. Here the keyword is normal; in the <em>normal</em> commute, Ken takes side streets instead of the toll road.
However, in this scenario, we have to come up with the equation that takes Ken's commute via <em>toll road</em>.
Ken can travel 3 times faster by taking the toll road (Given), which can be represented in the mathematical terms in terms of x as follows:
<em>Without considering Ken getting late, </em>the equation would become the following:
--- (A)
<em>As Ken is leaving late</em>, we have to incorporate that time as well by <em>adding</em> it in the aforementioned equation (A).
In this case, it's 20 minutes; therefore, the equation (A) will become:
Hence, the correct answer is .
