There are between 50 and 60 eggs in a basket. When Mohammed counts by 3's, there are 2 eggs left over. When he counts by 5's there are 4 left over. How many eggs are there in the basket?
The correct answer is:
59
Explanation:
The numbers between 50 and 60 that are divisible by 3 are
51, 54, 57, 60
The numbers between 50 and 60 that are divisible by 5 are
50, 55, 60
We know that when he counts by 3s, he has 2 left over; this means the number he counts to is 2 fewer than the number of eggs. This means, counting by 3s, we could have
51+2, 54+2, 57+2, or 60+2 = 53, 56, 59, 62
62 is not an option, since we know we have between 50 and 60 eggs; this gives us 53, 56 or 59.
We also know that when he counts by 5s, he has 4 left over; this means the number he counts to is 4 fewer than the number of eggs. This means, counting by 5s, we could have
50+4, 55+4, 60+4, or 54, 59, 64
64 is not an option, since we know we have between 50 and 60 eggs; this gives us 54 or 59.
The only number in both lists is 59, so this must be the answer.

Mick has a bag with 2 mint sticks, 11 jelly treats, and 7 fruit tart chews. If he eats one piece every 10 minutes, what is the probability his first two pieces will be a jelly treat and a mint stick?
Give your answer in a percent.
To find the probability, calculate the probabilities of selecting a jelly treat and a mint stick. Then multiply these probabilities together to find the overall probability.
Explanation:To find the probability that Mick's first two pieces will be a jelly treat and a mint stick, we need to calculate the probability of selecting a jelly treat and a mint stick from the bag.
First, we need to find the total number of pieces in the bag: 2 mint sticks + 11 jelly treats + 7 fruit tart chews = 20 pieces.
The probability of selecting a jelly treat as the first piece is: 11 jelly treats / 20 total pieces = 0.55 or 55%.
After Mick has eaten one piece, there are now 19 pieces left in the bag.
The probability of selecting a mint stick as the second piece is: 2 mint sticks / 19 remaining pieces = 0.105 or 10.5%.
Therefore, the probability that Mick's first two pieces will be a jelly treat and a mint stick is 55% * 10.5% = 0.055 or 5.5%.

There are 2 general steps to solving a linear equation of one variable:
1. add or subtract both segments with the same number so that it is expected that in one segment there are only variable modifiers or constant numbers 2. Change the equation into a simple form so that the coefficient of the variable is 1This can be done by dividing or multiplying by equal numbers
An equation will remain equivalent if both segments are multiplied or divided by the same number

What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?
A. x = −6
B. x = −4
C. y = −6
D. y = −4
we know that
The given line is parallel to the x-axis
so
the equation of the line that is parallel to the given line and passes through the point [tex](-4,-6 )[/tex] will be equal to the y-coordinate of the point
The y-coordinate of the point is [tex]-6[/tex]
therefore
the equation is

Harry buys a sofa set that costs $2000.00. He pays for it by installments at an interest rate of 5% per year. What is the total amount he has to pay at the end of the one year?
Harry is required to pay an additional $100 as interest for one year on the $2000 sofa, bringing the total payment to $2100 at the end of the year.
Harry buys a sofa set at a cost of $2000 with an installment plan that includes an interest rate of 5% per annum. To calculate the total amount Harry needs to pay at the end of one year, you need to calculate the interest and then add it to the principal amount.
The interest for one year is calculated as follows:
Interest = Principal imes Rate imes Time.
Interest = $2000 imes 5% imes 1 year.
Interest = $2000 imes 0.05 imes 1.
Interest = $100.
Now, we add the interest to the principal amount to find the total amount Harry has to pay by the end of the year:
Total Amount = Principal + Interest.
Total Amount = $2000 + $100.
Total Amount = $2100.
Therefore, Harry will have to pay a total of $2100 at the end of one year.

Which of the binomials below is a factor of this trinomial? x2 - 3x - 4
A. x2 + 4
B. x + 4
C. x - 4
D. x + 8
Answer:
c) x - 4
Step-by-step explanation:
To do a factorization of this kind of trinomial there is a technique very easy to do it.
First, you need to see the numbers that are along with the x and the independent number.
In this case -3 and -4 (I will call them b and c)
Next, you need to think in two numbers that can acomplish the following:
x * y = c
x + y = b
So, first, think, which are two numbers that you can multiply between them to give as a result -4?.
In this case it would be -4 and 1 (-4*1 = -4)
These numbers if you do a sum you'll get -3:
-4 + 1 = -3
So the factorization becomes this:
(x - 4) (x - 1)
So, one of the factors is x - 4. Option c
If |x| = 6 then x = -6 or
