Answer:
Ebony will win the competition
Step-by-step explanation:
<u>Kiara:</u>
where t represents the time in seconds, and m represents the number of math facts completed.
When t = 1, then m = 5
5 math facts per second
<u>Giovanni:</u>
From the table:
20 math facts - in 5 seconds
40 math facts - in 10 seconds
60 math facts - in 15 seconds
4 math facts per second
Ebony:
From the graph
12 math facts in 2 seconds
24 math facts in 4 seconds
36 math facts in 6 seconds
48 math facts in 8 seconds
60 math facts in 10 seconds
6 math facts per second
Ebony will win the competition
Answer:
Step-by-step explanation:
y = 3 - xy
Let x = 1
y = 3 - (1)y
Expand brackets.
y = 3 - y
Add y to both sides.
2y = 3
Divide both sides by 2.
y = 3/2
Answer:
Step-by-step explanation:
10 - 4m + 7m = m - 10
Simply both sides:
10 + -4m + 7m = m + -10
Combine like terms:
( -4m + 7m) + (10) = m - 10
3m + 10 = m -10
3m + 10 = m - 10
Subtarct m from both sides:
3m + 10 - m = m - 10 - m
2m + 10 = -10
Subtract 10 from both sides:
2m + 10 - 10 = -10 - 10
2m = -20
Divide both sides by the 2:
2m/2 = -20/2
m = -10
<u>Answer =====> m = -10</u>
