This is a pretty basic multiplication problem.
If one box has 789 pieces of paper in it and there are 25 boxes, you will simply multiply 789 x 25
789 x 25 = 19,725.
This shows that there are 19,725 pieces of paper in the 25 boxes of paper.
Since Angles B and C are equal, the sides AB and AC must also be equal, so you can set the equations equal to each other and solve for x. Then to find the length of BC, x can be plugged into the equation for that side length.
4x+4=6x-14
Add fourteen to each side to get x alone on the right side
4x+4+14=6x-14+14
4x+18=6x
Subtract 4x from each side to get all of the x's on one side of the equation
4x+18-4x=6x-4x
18=2x
Divide each side by two to find the value of one x
18/2=2x/2
9=x
Now that you know x equals 9, plug that into the equation for side length BC:
2x+7
2(9)+7
Multiply 2 by 9 to get rid of the parentheses
18+7
Add to simplify
25
The side of the triangle, BC, equals 25
Well a decameter is 10 meters so if she has 250 meters then she has 25 decameters Hope this helps!
Answer: 3
Step-by-step explanation:
The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
