The system has infinitely many solutions. Rearranging the left side of the 2nd equation and subtracting 3a from both sides gives −ax + ay = _a. Dividing both sides by −a gives x − y = ___. So, the equations describe the same line. Because every point on the line is a solution of the equation, and thus of the system, there are infinitely many solutions.

So we know that × is less than 14.3 subtract by 9.

We can figure out what × is is by subtracting 14.3 with 9 and then find the answer less than it.

[tex]14.3-9=5.3[/tex]

So now we know that the answer can be 5.3 or more. This means that we can cross out 5.3, 6.4, and 7.5.

kenny made cookies. he used 7/12 of a cup of flour and 1/4 of a cup of sugar. how much more flour the sugar did kenny use?

Answers

ANSWER:

he used 1/3 cup more flour than sugar

EXPLANATION:

7/12 - 1/4 is the equation

multiply the numerator and denominator of 1/4 by 3 so the denominators are the same. it would be 3/12

7/12 - 3/12 = 4/12

simplify

4/12 = 1/3

1/3 cup is your answer i hope this helps!

Answer:

The answer is 4/12

Step-by-step explanation:

Since you can't simplify 7/12 you would multiply the denominator of 4 by 3 and the numerator of 1 by 3 getting the fraction of 3/12.

After that you'd subtract 7/12 by 3/12 to get an answer of 4/12 or 1/3.

A certain bank pays 3.4% interest per year for a certificate of deposit, or
CD. What is the total balance of an account after 18 months with an initial
deposit of $1,250?

a. 765$
b. 2,015$
c. 63.75$
d. 1,313.75$

Answers

STEP BY STEP

A = $1,313.75

Equation:
A = P(1+rt)

Calculation:

First converting R percent to R a decimal
R = r/100 = 3.4%/100 = 0.034 per year.

Putting time into years for simplicity,
18 months / 12 months/ year = 1.5 years

Solving our equation:
A = 1250(1+[0.034 * 1.5]) = $1,313.75

The total amount accrued, principal plus interest, from simple interest on a principal of $ 1,250.00 at a rate of 3.4% per year for 1.5 years (18 months) is $1,313.75

The ANSWER would be

D. $1.31375

$[tex]1,313.75[/tex] is the total balance of an account after [tex]18[/tex] months with an initial deposit of $[tex]1,250[/tex]

What is balance?

In banking and accounting, the balance is the amount of money owed on an account. In bookkeeping, “balance” is the difference between the sum of debit entries and the sum of credit entries entered into an account during a financial period. When total debits exceed total credits, the account indicates a debit balance.

What is Interest?

In finance and economics, interest is payment from a borrower or deposit-taking financial institution to a lender or depositor of an amount above repayment of the principal sum, at a particular rate. It is distinct from a fee which the borrower may pay the lender or some third party.

According to questions, a certain bank pays [tex]3.4[/tex]% interest per year for a certificate of deposit, or CD.

We have to find the total balance of an account after [tex]18[/tex] months with an initial deposit of $[tex]1,250[/tex]

Total balance can be calculated using the following formula:

[tex]A = P(1+rt)[/tex]

Here [tex]r=\frac{3.4}{100} =0.034[/tex]

[tex]t=\frac{18}{12} =1.5[/tex]

So,[tex]A = 1250(1+0.034[/tex]×[tex]1.5[/tex])

[tex]=[/tex]$[tex]1,313.75[/tex]

Therefore,$[tex]1,313.75[/tex] is the total balance of an account after [tex]18[/tex] months with an initial deposit of $[tex]1,250[/tex]

Hence, we can conclude that Option(d) is correct.
