For this case, the first thing we must do is define variables.
We have then:
x: time in minutes
y: distance traveled.
We then have the following equations:
For Kathleen:
For Arnob:
By the time Arnob reaches Kathleen we have:
From here, we clear the value of x.
We have then:
Answer:
it takes Arnob to catch up to Kathleen 75 minutes:
d. 75
If the problem says "space", that usually means that they are talking about volume. The maximum length the box can be is 8.4 inches. To find volume, you do length * width * height. You know the length and height, as well as the volume. You can replace the width with "x". Your equation should be:
11.5 * 8.4 * x = 272.8
Then you can just solve for x by dividing both sides by (11.5 * 8.4). The answer should be about 2.82 inches.
Answer:
yes it is.
x = 4 and y = -3
Step-by-step explanation:
Solve simultaneously using elimination method:
equation 1 - equation 2
3x + y = 9 equation 1
-2x + y = 5 equation 2
_________
x = 4
plug 4 into any of the 2 equations and solve for y.
3(4) + y = 9
12 + y = 9
12-12 + y = 9-12
y = -3
Answer:
sqrt of 100 = 10
So the answer is less than 10
6, -5, -10, -14
THese are the answers
Answer:
Step-by-step explanation:
6w+3wy-4x-2xy
Factorization found :
(3w - 2x) • (2 + y)
Trying to factor a multi variable polynomial :
1.1 Split 6w + 3wy - 4x - 2yx
into two 2-term polynomials
+ 3wy + 6w and - 4x - 2yx
This partition did not result in a factorization. We'll try another one:
6w + 3wy and - 4x - 2yx
This partition looks good
1.2 Pull out from each binomial separately
6w + 3wy = 3w • (2 + y)
- 4x - 2yx = - 2x • (2 + y)
1.3 Add up to arrive at the desired factorization
(3w - 2x) • (2 + y)
Factorization found :
(3w - 2x) • (2 + y)
