We can find this integer using a system of equations. The first thing we look at is the first sentence.
Let's call X The first integer,
Let's call Y the second integer.
So, X+Y=61 and X-Y= 1
Using Substituion on the second equation, we get
X=Y+1
(Now we plug in Y+1 into the second equation for X)
So,
(Y+1)+Y=61
2Y=60
Y=30
So, one of the integers is 30.
Now to find the second, we go back to
X=Y+1
X=30+1
X=31.
So, the integers are 31 and 30.
Hope this helps!
Answer:
Step-by-step explanation:
Since the y-axis is cross on 5, that's the slope.
y=mx+5
To find x, let's use the formula;
Answer:
Step-by-step explanation:
- In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value, . In this case, we need to isolate in the first equation so that both equations .
- With this, we now know that both and are equal to , so we can set them equal to each other.
- Reply to this if anything I'm saying or doing is confusing in any way, or if you find a mistake. :) Solve for .
- Hopefully this answer is correct AND makes sense in terms of how I achieved it. Again, reply to this with any questions or mistakes I made and I'll do my best to answer or fix them.
If you times 4 by 20 you would get 160 then you add the 25 per month and then you would get 185
Let x = commissions
Let y = total earnings
y = 0.20x + $750. Plug your numbers in.
$4,000 = 0.20x + $750. Subtract 750 from each side.
$3250 = 0.20x. Divide each side by 0.20.
$16,250 = x.
The salesperson needs to sell $16,250 in commissions to earn $4,000 in total earnings each month
