<h3><u>Given inequality:</u></h3>
Answer:
It's the 1st one:
Step-by-step explanation:
There is a correct way to do this, but because it's multiple choice you can plug any value, preferably not any negatives, 0 or 1, into the x and then calculate. I plug 2 in for x and got 5 as my answer then I went to the answers and the 1st equaled 5
Answer:
Step-by-step explanation:
Let shakes be s and hamburgers be h. Then the total cost equation would be
2s + 3h = 17
The next equation in our system will be
3s + 4h = 24
You can solve this by either substitution or elimination. I'm going with substitution because it's easier in this platform to do so. I'm going to solve the second equation for h.
4h = 24 - 3s and
h = 6 - .75s
Now we will sub that into the first equation to get
2s + 3(6 - .75s) = 17 and
2s + 18 - 2.25s = 17 and
-.25s = -1 and
s = 4
That means that shakes cost $4 each. Now plug in 4 for s and solve for h:
h = 6 - .75(4) and
h = 6 - 3 so
h = 3 so hamburgers cost $3 each.
Answer:
1/√2
Approximate numerical value
1/√2 = 0.707106781186548
---------------------------
Rationalize the denominator
(1/√2) * (√2 / √2) = √2 / 2
Answer:
For a given length l and width w, the new perimeter is....
2(l + w) + 8
Step-by-step explanation:
Currently, the rectangle's perimeter is 2(l + w). You knew that.
Now, the question asked you to change l into l + 7, and w into w - 3. Substitute them, so we get
Perimeter New = 2(l + 7 w - 3) = 2 (l + w + 4)
Then, I chose to "pull out" + 4, so I multiply it with the 2. Hence, we get
Perimeter New = 2 (l + w) + 8
