Answer:
-14
Step-by-step explanation:
1. Carry out the indicated multiplication, obtaining 24a + 48 = 18a - 36.
2. Combine like terms: 6a = -84.
3. Divide both sides by 6 to isolate a: a = -84/6 = -14
Answer:
1 ÷ 6
Step-by-step explanation:
Let us assume the probability of the red marble for selecting it first time be x
And, it is to be done 3 times
that means
= 1 ÷ x × 1 ÷ x × 1 ÷ x
This equivalent to = 1 ÷ 216
And the 216 could be calculated by multiplied 6 3 times i.e.
= 6 × 6 × 6
= 216
So, the probability for selecting it for a first time is
= 1 ÷ 6
Here are some solutions: (there are actually an infinite amount of them)
x = 0 , y = 7
x = 1 , y = 8
x = 2 , y = 9
x = 3 , y = 10
x = 4 , y = 11
x = 42 , y = 49
x = pi , y = pi + 7
Fifty five percent times two hundred and sixty equal one hundred and forty three
No solution because 12x + 8 does not equal 12x + 12
