Step by step explanation: -28-15
When adding negative with positive it will always be negative so for this question, subtract -28 with 15 which would be -43. So -43 would be the temperature in the evening.
U would measure it with the teaspoon and the 1/6 teaspoon
you would need 2 use the 1/2 teaspoon 4 times to get 2 teaspoons and the `1/6 teaspoon 4 times to get 2/3.
1/6+1/6=2/6*2=4/6 =2/3
hope this helps
20 students.
40% are boys. (40/100)*20 = 0.4 * 20 = 8 boys.
Girls= 20 - 8 = 12 girls.
25% of the boys wear glasses. = (25/100)*8 = 0.25*8 = 2 boys wear glasses.
50% of the girls wear glasses. = (50/100)*12 = 0.50*12 = 6 girls wear glasses.
Total students that wear glasses = 2 + 6 = 8 students.
8 students wear glasses.
