Answer:
No
Step-by-step explanation:
If you’re wanting the yes or no answer, keep reading.
If you’re wanting a number for y and x, we can’t give that to you. It’s infinite!
Since both y and x = 0, the equation would be set up as 0 = 0-3. You can see the equation is false, so it would be a no.
To solve this you just move the letters and numbers around until you get a different equation that is the same as the original equation.
You can also rule out the last two answers because they don’t have all the values.
P = pie
s=2prh can be written as s/2ph=r if we divide s by 2ph because we need to isolate r because all the answers have r isolated.
So the answer would be b s/2ph=r
Sorry that’s really badly worded and confusing, but I hope it helps.
Answer:
Voters can select their members in 10possible ways
Step-by-step explanation:
According to the question, the voters are to elect 3members out of 5 candidates, this means they are to select any 3 candidates of their choice from a pool of 5 candidates. Since "combination" has to do with selection, we use the combination formula.
To select 'r' objects from 'n' pool of objects, we have;
nCr = n!/(n-r)!r!
5C3 = 5!/(5-3)!3!
5C3 = 5!/2!3!
5C3 = 5×4×3×2×1/2×3×2
= 120/12
5C3 = 10
Candidates can therefore vote in 10 possible ways
That's a lot of questions. First, they're asking for how much each person pledged. Ivan said he would give $4.25, plus $1.25 per mile. As an expression, that would be 1.25m+4.25 . Vicky said that she would give $5.75, plus $.75 per mile, which would be .75m+5.75 . The second problem asks you to add the two, so add 1.25m and .75m to get the total amount she would earn per mile, which is $2. If I got paid $2 for every mile I biked, I would bike a marathon. Then add the flat payments of $4.25 and $5.75, and you get $10. So, the final equation would be 2m+10.
The last question is asking for you to find an equivalent proportional expression. To find this, you can just dividing by the greatest common factor of the two numbers. I got 2, so the equation would be 1m+5.
