Answer:
x=20
Step-by-step explanation:
180=2x+6x+20
180=8x+20
160=8x
20=x
Answer:
X = 1 - (1/4) - 2 * (1/4)
Step-by-step explanation:
The equation to be raised must take into account what is painted on Monday and Tuesday. First consider the wall as a unit, that is to say painting the entire wall (100%) is equivalent to 1. Therefore the equation would be the following:
Let X be the unpainted part:
<em>X = 1 - (1/4) - 2 * (1/4)
</em>
X = 1 - (1/4) - (1/2)
Now, if we solve this, we have that 0.25, therefore 25% or 1/4 is left to be painted on the wall.
We see that the total legnth is 9 and 5/8 inches
each piece is 1 and 3/8 inches long
there are 7 pieces
a board that is 9 and 5/8 inches total legnth is cut into pieces that measure 1 and 3/8 inches is cut into 7 pices
not A, should be cut into 7 pices, not 9 and 5/8
not B because the board is 9 and 5/8 long
the answer is C
Answer:
25.13 (to 2 d.p)
Step-by-step explanation:
Use the formula:
Length of arc = (angle/360) X 2πr
where: angle = 180 and r = 16÷2 = 8
