Answer:
1001/1500
Step-by-step explanation:
The easiest method for doing this is to just average the two numbers.
e.g. to find a number x between the two numbers ab and cd
x=12[ab+cd]
=12[adbd+bcbd]
=ad+bc2bd
In this case…
x=(2×5)+(3×4)2×2×5=10+1230=2230=1115
You can easily see where that came from.
23=1015 and 45=1215
and the ‘common denominator’ means you just have to pick a value between 10 and 12 . i.e. 11
But you can also say…
23=100150 and 45=120150
and choose any of 101150,102150,...,119150
or
23=10001500 and 45=12001500
and choose any of 10011500,10021500,...,11991500
A then b
first photo a, second is b
1. The answer would be -1 because the variable term is -y which can also be written as -1y and the coefficient is the number before the variable.
2. The answer would be 19. If you plug 3 into the equation for x you would get 4 + 5(3). Five times three is 15, and 15 plus 4 is 19.
Answer:
20
Step-by-step explanation:
You do have some idea of how the question is done. It won't take much to learn the right answer.
braces = square root( length^2 + height^2)
braces = √( (12)^2 + (16)^2) )
braces = √(144 + 256)
braces = √(400)
braces = 20
Answer: $24.50
Step-by-step explanation:
Since the shirts were on sale for $19.95 each, both shirts would cost:
= $19.95 × 2
= $39.90
We are further told that he saved a total of $9.10. This means the original cost for both shirts would be:
= $39.90 + $9.10
= $49.00
Then, the original price for each one would be:
= $49.00 / 2
= $24.50
