Answer:
n = -45
Step-by-step explanation:
(n-5) /10 = -5
Multiply each side by 10
(n-5) /10 *10= -5*10
n-5 = -50
Add 5 to each side
n-5+5 = -50+5
n = -45
Answer:
$200
Step-by-step explanation:
Let X be the amount of Christmas money he had at the beginning.
He put 65% of X in the bank. This is 0.65x
He has $70 left which is equal to 0.35x
We need to write an equation to find the value of x.
70 = 0.35x
Divide by 0.35 to find the value of x.
70/0.35 = 0.35x/0.35
200 = x
He received $200 for Christmas.
Answer:
The probability that neither is available when needed
Step-by-step explanation:
A town has 2 fire engines operating independently
Given data the probability that a specific engine is available when needed is 0.96.
Let A and B are the two events of two fire engines
given P(A and B) = 0.96 ( given two engines are independent events so you have to select A and B)
Independent events : P( A n B) = P(A) P(B)
The probability that neither is available when needed
Answer:
3/12 = 4/12
or
3/12 = 1/3
being are last boxes to autofill.
Step-by-step explanation:
1/12 +1/4 = 1/12 + 3/12 = 4.12 = 1/3
When adding the rule of fractions is where required make all denominators the same by dividing the one you want to change to- by the subset one you are changing.
12 / 4 = 3
we get 3/12
Then when adding same denominators 1/12 + 3/12 we just add the top values. = 4/12
The last box would be 4/12 but if asked to simplify we would automatically enter 1/3 for simplification.
As 4/12 = 1/3
Answer:
Cost in shop A is lesser.
Step-by-step explanation:
Given:
Shop A 4 batteries cost = £1.60
Shop B 6 batteries cost = £2.70
Find:
Lower price
Computation:
Cost in shop A = £1.60 / 4
Cost in shop A = £0.4
Cost in shop B = £2.70 / 6
Cost in shop B = £0.45
Cost in shop A is lesser.
