X=100 because 20 X 5 is 100
Answer:
16 cm
Step-by-step explanation:
Let the width be x
The length will be 3 x since the length is three times the width
Perimeter=2(l+w) where l is length and w is width
By substituting 128 cm for perimeter, x for w and 3 x for l then
128=2(3x+x)
128=8x

Therefore, the width is 16 cm, the width is 16*3=48 cm
31/100 represents the yellow marbles because 3/10 = 30/100, 2/10 = 20/100, and 19/100.It all adds up to 69/100 marbles.
Answer:
yes
Step-by-step explanation:
396÷ 9= 44
44×60= 2,640 > 2500
The independent variable would be “d meters” because the amount of time depends “dependent variable” on the height of the fall
