Answer:
Step-by-step explanation:
If you add a number that is negative, you are basically subtracting it.
This means that
Since they both have the same denominator, you can easily subtract the fractions: 
Answer:
$78.69
Step-by-step explanation:
63.04+58.27=121.31
200-121.31=78.69
Answer:
43 over 9 is the fraction you are looking for.
Step-by-step explanation:
The period required to pay for the car is not given. However let us assume this interest rate of 6.5% is per annum, on simple interest terms.
I= PRT
where I is the interest accrued, P is the principal, R is the rate and T is the time.
If the car is paid for in one year then the final cost will be:
I = 29990 × 6.5% × 1
6.5% must be expressed as a decimal fraction so we divide by 100 to get 0.065
I= 29990 × 0.065 × 1
I = 1,949.35
29990 + 1949.35 = 31939.35 dollars.
If the car is paid for in five years on simple interest terms then the final cost will be :
I = 29990 × 0.065 ×5 = 9,746.75
29990 + 9.746.75 = 39,736.75 dollars
The solution of simultaneous equations is x=4 and y = -1.
<h3>What are
Simultaneous equations?</h3>
Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables satisfies all such equations.
We can solve simultaneous equations by various methods. here we will solve it by elimination method.
Here we have two simultaneous equations
3x -2y = 14 --- (i)
and 4x + 3y = 13---(ii)
Now multiplying (i) by 3 and (ii) by 2 we get
9x -6y = 42 and 8x + 6y = 26.
Now adding both we get
17x = 68 ⇒ x = 68/17 ⇒ x = 4.
Substituting the value of x in (i), we get
3*4 - 2y = 14 ⇒ -2y = 14-12 = 2 = -2/2 ⇒ y = -1.
Therefore, the values of x and y are 4 and -1 respectively .
