For this case, the first thing we must do is define a variable.
We have then:
x: number of initial cards.
We write now the equation that represents the problem:
x - (4) * (6) = 54
From here, we clear the value of x:
x = (4) * (6) + 54
Rewriting:
x = 24 + 54
x = 78
Answer:

Answer:
64 members
Step-by-step explanation:
88 total members
24 are in the students council
so those in the dance team and not in the council:
88-24 = 64.
42 degrees should be right
Answer:
1/9
Step-by-step explanation:
For each of the first die's 6 outcomes, the second die also has a possible 6 outcomes.
6 × 6 = 36
There are 36 different outcomes from
1, 1
1, 2
1, 3
...
6, 6
Many outcomes have the same sum. For example, 3, 4 and 4, 3 both add to 7.
How many outcomes add to 9?
3, 6
4, 5
5, 4
6, 3
4 different outcomes out of a possible 36 different outcomes add to 9.
p(sum of 9) = 4/36 = 1/9
