We can solve this by setting up 2 equations. We can use any letters like. For now, I'll use x and y.
So now we know that x - y = 0.7 and x + y = 1.
Now we can eliminate one of the letters by adding or subtracting one equation from the other. I am going to eliminate y by adding the two together (the y and the -y cancel).
This gives us 2x = 1.7, and so x = 1.7 ÷ 2 = 0.85
Finally, we can substitute x for 0.85 back into one of the original equations to figure out what y equals. I'm going to use x + y = 1.
So now we have 0.85 + y = 1, so y = 1 - 0.85 = 0.15
The numbers, therefore, are 0.85 and 0.15 (you can check by using the other equation).
Hope this helps!
Answer:
A
Step-by-step explanation:
Area of a triangle = 
where b = base length and h = height
the triangle shown has a base length of 2 and 1/2 and a height 4. and 2/5
So area =
5.5 also = 
Hence, the correct answer is A
Answer:
if im understanding right, answer is 207
Step-by-step explanation:
1000 + 1000 = 2000
7 x 10 = 70
2070 / 10 = 207
I believe 2x - 9 is correct. Correct me if I am wrong
