C) (3, 3.9)(65, 84.5)(24, 31.2)
D) (11, 13.2)(99, 118.8)(20, 24)
the ratio 7:22 represents the ratio of students who prefer doing their homework before school to all students that do their homework
Choose 3 answers:
A) 13 = 9 + m
B)7- m = 3
C) 15 = 11m
D) 5 = m + 2
E) 20 divide m =5
Answer:
A, B, E
Step-by-step explanation:
A) 13=9+m
m= 13-9
m=4 ✔️
B) 7-m =3
m= 7-3
m=4 ✔️
C) 15= 11m
15=11*4
15≠44
D) 5= m+2
If m=4 therefore
5≠4+2
5≠6
E) 20 divide m = 5
20/4 = 5
therefore, m=4 ✔️
By substituting m=4 into each equation, we find that options A) 13 = 9 + m and E) 20 divided by m = 5 are the correct equations where m=4 is a solution.
In mathematics, specifically algebra, we can solve and check equations by plugging in values. You are asked to find the equations where m = 4 is a solution.
Let's substitute m with 4 in each equation:
Therefore, the equations where m=4 is a solution are A) 13 = 9 + m and E) 20 divided by m = 5.

Answer:
Step-by-step explanation:
plug in 24 for y and 9 for x, to get 24 = 9k, so k = 24/9=8/3
