9+3=12
30+20=50
300+100=400
Then add.
12+50+400=462
<span>So 339+123=462</span>

1 over 64
8^2 = 64 , 8^-2 = 1/(8^2) = 1/64
For this case, the first thing we must do is find the scale factor.
For this, we use one of the dimensions. We will use the width of the photo.
We have then:

Then, we look for the value of the height of the new photo. To do this, we multiply the scale factor by the original dimension.
We have then:

Answer:
the new height will be:
d.168 inches
They took $10 from 10 people that saw and wanted to try the ad.
4. k less than 3.5, so a number k is being taken away from 3.5:
The answer is 3.5-k
5. the sum of g and h, reduced by 11, so you need a set of parentheses to write this one: (g+h)-11
6. 5 less than y, plus g, so do a combination of the strategies used in the previous two problems and you will get: (y-5)+g
7. 5 less than the sum of y and g, you are taking away 5 from the sum of two numbers, y and g, so: (y+g)-5
Hope this helps :-)
