5 girls : 4 boys
5 + 4 = 9 students
= 27 students ( 5girls / 9 students )
*cancel students units*
= 27 ( 5 girls / 9)
= 15 girls
Perimeter of triangle = 3(side)
P = 3(s)
12 = 3s
12/3 = s
4 = s
I think there is a typo in your post.
The question should be: WHICH ONE OF THE FOLLOWING IS A POSSIBLE SIDE OF THE TRIANGLE?
In that case, 4 cm is the answer. However, 4 cm is not listed among the choices. So, choice d is the answer.
Ok so
1/4 of total eaten
3/4 left
3/5 of 3/4 eaten
9/20 left
18=9/20 of whole
multiply both sides by 20
360=9 of whole
divide both sides by 9
40=whole
40 total originlly
Answer:
x = -5
Step-by-step explanation:
I) Substitute:
3x + 2y = -5
3x + 2(5) = -5
3x + 10 = -5
II) Solve:
3x + 10 = -5
3x = -15 (Subtract 10 from both sides)
x = -5 (Divide both sides by 3)
5x+2=3x+8 subtract 2 from both sides 5x=3x +6 subtract 3x from both sides 2x=6 divide by 2 x=3 now plug 3 into angle b to give you 17 degrees
