Answer: 4:20
Step-by-step explanation:
60 lbs can be divided into three groups, in this case the bags of sand, so 60 divided by 3 is 20.
Now you have the 8 lbs left. It gets divided into two groups/bags so you would do 8 divided by 2 is 4.
Then for your ratio it is cement to sand which is 4:20. You can write the ratio however way you want or what is required by the question.(fraction bar, ‘to’, or colon ‘:’ )
Hope this helps!
So you want to find how much y=8 and how much x=3 so to do that you multipy 8x3 witch =24 so 8x3=24 ope this helps you.
Answer:
x = 4
, y = 2
Step-by-step explanation by elimination:
Solve the following system:
{2 x + 3 y = 14 | (equation 1)
x + 5 y = 14 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + 3 y = 14 | (equation 1)
0 x+(7 y)/2 = 7 | (equation 2)
Multiply equation 2 by 2/7:
{2 x + 3 y = 14 | (equation 1)
0 x+y = 2 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{2 x+0 y = 8 | (equation 1)
0 x+y = 2 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 4 | (equation 1)
0 x+y = 2 | (equation 2)
Collect results:
Answer: {x = 4
, y = 2
The image would then be in quadrant 3 because say you "folded" the coordinate plane across the x-axis, then the point attached onto the other side of the plane, the point would be in the 3rd quadrant.
