Answer:
The correct answer is B.
We have 4 / 10 = ( 2 x 2 ) / ( 2 x 5 );
6 / 15 = ( 3 x 2 ) / ( 3 x 5 );
8 / 20 = ( 4 x 2 ) / ( 4 x 5 );
Step-by-step explanation:
Answer:
The combined length is 61 inches
Step-by-step explanation:
we know that
To find out the combined length of all the pieces Meg measured, multiply each measure by the number of pieces and then sum all the values
Let
x -----> the combined length
we know that
we have
1 piece of 3 inches
2 pieces of 5 inches
3 pieces of 6 inches
3 piece of 7 inches
1 piece of 9 inches
so
therefore
The combined length is 61 inches
Answer:
$337.5
Step-by-step explanation:
4:5=360:x 360/4=90 90+360=450 check 360/450=0.8 and 4/5=0.8
4:5=360:450
larger farm perimeter is 450 yards so dig a trench 0.75 per yard
so 450 * 0.75 = $337.5
Hope this helps! :)
Answer: System 1 has an infinite number of solutions and System II has no solutions.
Step-by-step explanation:
If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.
If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.
