Answer:
1-True
2-True
3-False
Step-by-step explanation:
1- All negative numbers are <0 and to the left on a number line. All positive numbers are >0 and are on the right of a number line.
2- When the number line moves to the right, the number gets larger.
3- You could have a negative number that is smaller than another number, but its distance from 0 could be greater. For example, -12 < 2. However, -12 is 12 places away from zero on the number line, but the number 2 is only two places away from zero on the number line.
Answer:
100 sweets
Step-by-step explanation:
Let initial number of sweet = x
Monday :
2/5 of x = 2x/5
Number left = x - 2x/5 = 3x/5
Tuesday :
2/5 of remaining = 2/5 * 3x/5 = 6x/25
Number left = 3x/5 - 6/25 = 9x/25
Wednesday :
2/3 of remaining = 2/3 * 9x/25 = 18x/75
Number left = 9x/25 - 18x/75 = 9x / 75
9x/75 corresponds to 12
9x/75 = 12
Cross multiply :
9x = 12 * 75
9x = 900
x = 900 / 9
x = 100 sweets
D. certain, because 1 means that 100% of the time the spinner will land on blue, meaning it doesn't land on anything else.
