645 feet.
Explanation:
We know that are 3 feet in a yard, so let's set up a proportion to solve this
x215
3 feet n
-------- = -----------
1 yard 215 yards
x 215
We are solving for n. To get from 1 to 215, we multiply by 215. So to get from 3 to the answer, we must multiply by 215 as well. 3 x 215 = 645, therefore that is the answer.
Four tenths is expressed as .4
five thousandths is expressed as .005
the sum of these is .405 and divided by 2 (there are two numbers we added), we get .2025, that is the average
Answer: -2 - (-7)
Step-by-step explanation: They both have the same outcome, 5. Which one is negative and one is positive. The last option is correct.
Answer:
Step-by-step explanation:
-3 / 1 8 9 -18
-3 -15 18
_______________
1 5 -6 0
The remainder here is 0 and the quoitient is 1x^2 + 5x - 6.
X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
