Answer:

Step-by-step explanation:
Given
Length of Pieces = 50cm
Number of Pieces = w
Left over = 20cm
Required
Determine the length of the wood
Start by multiplying the number of pieces by the length of each pieces



Lastly, add the leftover to get the actual length of the wood

Substitute 50w for Result and 20 for Leftover

<em>Hence, the length of the wood is 50w + 20</em>
Answer:
For (2, 8) the slope is 2
For (-4, -4) the slope is -4
Step-by-step explanation:
The slope is the x axis which goes first
and the y intercept would be the y axis which goes second
Slope goes before the y intercept
for example: (8, 4) the slope is 8 the y intercept is 4
Pretty sure it's A ?? That's what I got. I'm taking this right now.
Answer:
3.75 quarts, rounded to 3.8 quarts
Step-by-step explanation:
3 quarts of solution is 10% antifreeze, so 0.3 quarts are already antifreeze, and 2.7 quarts are not.
a(the antifreeze we already have)+x(what we're going to add)= 1.5*2.7
Let me explain. If we have 60% antifreeze, 40% is not. 60/40=1.5
Substitute a for 0.3
0.3+x=4.05 Subtract 0.3 from both sides
x=3.75
