So if all same you just simplify The top : 2x+1+x+4 2x+x+1+4
3x+5 The bottom all same just use one .x-3 3x+5/x-3
Answer: D
Step-by-step explanation:
A. 3 + -7 < -4
-4 < -4
X
this one isn’t a solution
B. 3 + -7 ≤ -4
-4 ≤ -4
this works, let’s try the other equation
3(3) + 2(-7) < -5
9 + -14 < -5
-5 < -5
X
this one doesn’t work either, let’s go on to the next one
C. the first equation is the same as the first one in A, and that didn’t work, so we know that the whole thing doesn’t work and we don’t have to do any math
D. we know the first equation works because we did it in B
let’s go on to the second equation
3(3) + 2(-7) ≤ -5
9 -14 ≤ -5
-5 ≤ -5
this works, so that means that both equations work and the whole thing works :)
Answer:
1: c
2: face
Step-by-step explanation:
pretty sure
Answer:
YW = 6
Step-by-step explanation:
a^2 + b^2 = c^2
x^2 + 8^2 = 10^2
x^2 + 64 = 100
x^2 + 64 - 64 = 100 - 64
x^2 = 36
√x^2 = √36
x = 6
Using the Instant-runoff method, it can be inferred that the winner is the tacos because after the first vote, they get 3 more votes that allow them to have more than half of the possible votes (option B).
<h3>What is the instant-runoff method?</h3>
Instant-runnof is a voting method whereby a single winner is selected from a wide variety of options. This method is characterized by allowing voters to choose different options on a scale of first option, second option, third option.
According to the above, in the first vote the sandwiches are eliminated because they had the lowest vote (3 votes). Then, a new vote must be carried out with the products that were left that were Pizza and Tacos.
On the second ballot, tacos get 3 more votes because voters who voted for Sandwich on the first ballot had Tacos as their second choice. So the bottom line is Pizza with 9 votes and Tacos with 11 votes.
In short, the Tacos win by having more than half of the possible votes 11/20.
