Answer:

4 1/2

Step-by-step explanation:

Look at this expression as given in the original problem; the numbers, properly typewritten, are -5 1/2, - 4 1/4, + 6 3/4.

We want to combine these three numbers into one.

To do this, we need the LCD; it is 4.

Thus, -5 1/2 is rewritten as -5 2/4.

Then we have

-5 2/4 - 4 1/4 + 6 3/4 = -5 -4 + 6 + 2/4 + 1/4 + 3/4.

This simplifies to: +3 + 6/4, or 3 + 1 + 2/4, or

4 1/2

Help please!! the ones with the X’s on the question numbers do not need to be answered! :)

Naddik [55]

me need slope and y intercept to get it in y=mx+b form (slope intercept)

Slope is the

difference in y / differences in x

differences in y = 6.5 -3 = 3.5

difference in x = 2 - 1 = 1

so slope is 3.5/1 or just 3.5

(now you can see the answer is c but lets check it by getting the y intercept too)

y intercept

this is when x is 0

the lowest x we see is 1 so if I go bacl to 0 in x the y must for back 3.5

3-3.5 is -0.5

so equation is y=3.5x -0.5 so the closest is c

If the product of nine tenths and eight tenths is subtracted from the sum of seven tenths and six tenths,what os the difference?

agasfer [191]

Product = multiply
Sum = addition
So 9 tenths * 8 tenths = 72 tenths
7 tenths + 6 tenths = 13 tenths
72 tenths - 13 tenths = 59 tenths or 5 and 9 tenths.

Delicious77 [7]

Answer:

Both Wolverine and James Bond will have paid the same amount after 10 months.

Step-by-step explanation:

Let x denotes the number of months after which both Wolverine and James Bond will have paid the same amount.

As Wolverine makes a $1000 down payment for a motorcycle and then pays $300 per month,

Amount paid by Wolverine in x months is equal to $1000+300x$

As James Bond makes a $2500 down payment for a motorcycle and then pays $150 per month,

Amount paid by James Bond in x months is equal to $2500+150x$

To find number of months after which both Wolverine and James Bond will have paid the same amount,

solve $1000+300x=2500+150x$

$1000+300x=2500+150x\\300x-150x=2500-1000\\150x=1500\\x=\frac{1500}{150}=10$

So, both Wolverine and James Bond will have paid the same amount after 10 months.
