Explain how to model the multiplication of 3 and ‒4 on a number line

1 answer:

4 0

First, start at zero. Now, because we are multiplying -4 by 3, we will jump over by 4 to the left ; 3 times on the number line. We should reach -12, and if we check our work, 3 x -4 = -12.

Answer:

At x intercept, x = 0

2.8(0)+5.7y+5.8=0

y=-5.8/5.7

=-1.02

At y intercept, y=0

2.8x+5.7(0)+5.8=0

x=-5.8/2.8

=-2.07

The Median of the data 78,56,22,34,45,54,39,68,54,84

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

The Median of the data 78,56,22,34,45,54,39,68,54,84

Median of a data is the value at the middle after rearrangement

Rearrange in ascending 0rder

22, 34, 39, 45), 54, 54, (56, 68, 78, 84

The two numbers at the middle are 54 and 54

Median = 54 + 54/2

Median = 108/2

Median = 54

Hence the median of the data is 54

The length of a bridge is 140 m. The length of each of Robert's paces is 55 cm.

Sindrei [870]

Answer:

255 steps

Step-by-step explanation:

They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:

140m * 100cm / 1m = 14000

Therefore the bridge would have a length of 14000 centimeters, we divide:

14000/55 = 254.54

Which means that Robert take at least 255 steps to fully walk the bridge.
