Answer:
The first answer is a = 10, The second answer is b = 7
Step-by-step explanation:
Equation 1: 5a = a + 40
To solve for a, you want to isolate a on one side of the equation. You can do this by subtracting "a" from both sides of the equation:
5a - a = a - a + 40
This simplifies to:
4a = 40
Now, divide both sides by 4 to solve for a:
4a/4 = 40/4
a = 10
So, a = 10.
Equation 2: 3b = 10b - 49
To solve for b, you want to isolate b on one side of the equation. First, let's get the "b" terms on one side by subtracting 10b from both sides:
3b - 10b = 10b - 10b - 49
This simplifies to:
-7b = -49
Now, divide both sides by -7 to solve for b:
(-7b) / (-7) = (-49) / (-7)
b = 7
So, b = 7.
B. 12
C. 6
D. 3
The number 3 can not be the common denominator for 2/3 and 1/2. The correct option is D.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Any number of equal parts is represented by a fraction, which also represents a portion of a whole. The number of components of a specific size is expressed as a fraction.
The fractions will have all the numbers 18, 12, and 6 as the common denominator but can not have 3 as a common denominator.
Therefore, the number 3 can not be the common denominator for 2/3 and 1/2. The correct option is D.

Answer:
Y=( x/2 )- 5
Where y is the number of pencils given to Jamil and 5 is the one kept by Maggie.
Step-by-step explanation:
Let's call the number of Katie pencil (x ).
So Katie gave half of her pencils to Maggie.(1/2x)
So Maggie keeps five pencils and give the rest to Jamil.
So
X/2 = 5 + y
Where y is the number of pencils given to Jamil and 5 is the one kept by Maggie.
Y=( x/2 )- 5
A.8/325=x/100
B.8/325=100/x
C.8/100=325/3
D.8/100=x/325
Using cash will not help you improve your credit rating.
b.
Using cash can be awkward when making large purchases.
c.
Using cash generally requires trips to the bank or ATM to keep cash on hand.
d.
Using cash can make it easier to over-spend since you know exactly how much you have.
The correct answer is:
D) Using cash can make it easier to over-spend since you know exactly how much you have.
Explanation:
Knowing exactly how much you have on hand will actually help you avoid over-spending.
When using cash, you are aware of exactly how much money you have. With a credit card, this may not be the case; this makes it easier with a credit card to spend more money than you should for your budget. With cash it's easier to avoid this problem.
The statement that is not a disadvantage of using cash instead of credit card is: Option D.
A credit card can be described as a payment card issued to an account holder, which allows card owners charge the card owner even beyond the deposit the individual has in their account.
The individual's account accrues a balance which the individual must pay in each month.
Using a credit card can be of disadvantage to an individual, because you may spend more than what you intend to spend.
Therefore, the statement that is not a disadvantage of using cash instead of credit card is: Option D.
