You said x + 2/5 = 12
It might be easier to handle if we use the decimal for 2/5.
x + 0.4 = 12
Subtract 0.4 from each side: x = 11.6
That's all there is to it. I'm sorry I can't make it
more complicated for you.
Answer:
b = 17.318 height = 23.318 ft
Step-by-step explanation:
This IS very similar to the other one, Emily..... Have you tried to solve it the same way?
b = 152 tan 6.5 = 17.318 ft (using a calculator)
add the height of the victim's head (6 ft)
17.318 + 6 = 23.318 ft
Answer:
1.875
Step-by-step explanation:
Answer:
1.12 x 10^6 or 1,120,000
Step-by-step explanation:
You work out the first part which would be (3.76 x 10^5) or 376,000.
Then you work out the second part which would be (7.44 x 10^5) or 744,000.
Then you add them together and move the decimal over to where the number is less than ten but greater than 0 so it would be like this:
1.120000
But just cut all the zeros so it would be like this:
1.12
And how ever many times you move the decimal over is the number you put beside the ten by the way. it should look a little like this by the time you are done:
1.12 x 10^6
208c + 52v = 5460
v = c + 10
where c = the price for a car rental and v = the price for a van rental.
To solve this system, use substitution; the second equation says v is equal to c + 10, so plug in "c + 10" for v in the first equation and solve for c:
208c + 52(c + 10) = 5460
208c + 52c + 520 = 5460
260c + 520 = 5460
260c = 4940
c = 19
Now that we have c, we can plug it in to the second equation to find v:
v = (19) + 10
v = 29
So, c = 19 and v = 29, meaning that
The cost of a car rental is $19 and the cost of a van rental is $29.
