First, distribute the minus sign across the second set. So you have:

x - y + 1 - x - y + 1

Now, we combine like terms:
x-x=0
-y-y=-2y
1+1=2

So we have -2y+2

Hope that helps.

Sue bought 3 t shirt for 8$ each. she paid with a $50 bill how much change should she get
muminat
Hi there!

First we need to calculate how much the 3 T-shirts cost and subtract that from the amount she paid to find the change.

First, we multiply to find the coats of the T-shirts.

3 × 8 = 24

Now, we subtract 24 from 50.

50 - 24 = 26

So, she got $26 of change.

Hope this helps!

How to put 634 in scientific form​
svetoff [14.1K]

Answer:

6.34 × 10²

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 634

New Number: 6.34

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 6 . 3 4

Decimal Count: 1 2

There are 2 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 6.34

b = 2

Now the whole thing:

6.34 x 10²

Step 4

Check your work:

10² = 100 x 6.34 = 634
