Answer:
x = 7 x = -6
Step-by-step explanation:
x^2−x−42=0
Factor
What two numbers multiply to -42 and add to -1
-7*6 = -42
-7+6 = -1
(x-7) (x+6) =0
Using the zero product property
x-7 =0 x+6 =0
x = 7 x = -6
75/5= 15 pints of juice per container
At least 24 times he need to deposit $ 50 to paying off his total purchase.

What is Savings?</h3>
Saving is the portion of income not spent on current expenditures. In other words, it is the money set aside for future use and not spent immediately.
Here, cost of mattress = $ 1399
cost of EMI = $ 78
Duration of EMI = 18 months
Total payable amount = 18 X 78
= $ 1404
Current account balance = $ 250
Per month savings = $ 50
Duration at which total balance is equivalent to payable amount
= (1404 - 250)/50
= 1154/50
= 23.08
Thus, At least 24 times he need to deposit $ 50 to paying off his total purchase.

Answer:
(a) She is 280m from her starting position
(b) 200m west then 80m south
Step-by-step explanation:
(a) 80m + 200m
= 280m
(b) First she walked 80m north n 200 east
If she want to get back to her starting position she will have to travel the same distance in the opposite direction
Opposite of East is West n opposite north is south
so she will have to go 200m west n then 80m south
Answer:
a. 5/12
b. 7/18
Step-by-step explanation:
In this question, we are interested in computing the probabilities.
Firstly, we need to get the sample space of the results. This refer to all possible results that can emerge from the rolling of the two die.
This can be found in the attachment.
What is important to know however is that the total number of possible results is 36;
so let’s compute;
a. For a, let’s circle all sums which are greater than 7 ;
We can see a total of 16 circled sums;
So the probability is 15/36 = 5/12
b. Sum divisible by 4 or 6 or both
Let’s make a circle again ;
So we have a total of 14
So the probability will be 14/36 = 7/18
