Answer:
120
Step-by-step explanation:
Let g = number of girls.
(2/3)g is 2/3 the number of girls
(2/3)g + 35 is 35 more than 2/3 the number of girls. This is the number of boys.
(2/3)g + 35 = 115
(2/3)g = 80
(3/2)(2/3)g = 80(3/2)
g = 120
Answer: 4.625
Step-by-step explanation:
remove parenthesis : 2/3 - 5/6 + 9/4 - 3/5
add fractions based on lcm : 40/60 - 50/60 + 135/60 - 36/60
equal denominator so combine fractions : 40 - 50 + 135 - 36 / 60
add/subtract : 40 - 50 + 135 - 36 = 89
answer ; 89/60
Perpendicular lines have slopes that are negative reciprocals
so if m1 = -3
the perpendicular line has a slope of 1/3
Answer:
<h2>x = 10</h2>
Step-by-step explanation:
ΔFGH ~ΔMNO ( given )
FG / GH = MN / NO. ( by Basic Proportionality Theorm )
so, therefore
6 / 9 = x / 15
x = 6×15 / 9
x = 90 / 9
x = 10
