1/4=2/8
7/8-2/8=5/8
so 5/8 foot of the board is left
The answer would have to be like the same as the first day, so that being said you would have to add. I think the answer is 2,2,4. hope this helps.
Answer:
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
2 • (3(5 + 2) - 1) =
Start with the innermost parentheses.
= 2 • (3(7) - 1)
Now do the multiplication inside the parentheses.
= 2 • (21 - 1)
Do the subtraction inside the parentheses.
= 2 • 20
= 40
In the triangle XYB
cos(x)=XY/XB
in the triangle AYZ
cos(z)=YZ/AZ
we know that
cos(x)=cos(z) and XY=YZ
therefore
XY/XB=YZ/AZ-------------- > (XY/YZ)=(XB/AZ) remember that XY=YZ
1=(XB/AZ)---------- > XB=AZ---------- > the statement was proved
