Answer: The denominator of a fraction tells you the relative size of the pieces. Therefore, the reason fractions need a common denominator before adding or subtracting is so that the numbers of pieces you are adding/subtracting are all the same size.

Answer:

We need to have a common denominator in order to subtract different fractions because if we have an example like.

5/2 - 6/8 we cannot do that because the denominator is not alike.

We have to use multiplication to help us here.

2 x 8 = 16 !

So. no we have 5/16

so now we do 5 x 8 = 40

So now my new fraction is - 40/16 BUTTTT 40/16 is an improper fraction. so 40/16 = 5/2

Now we are back at the square 1 so now we have to fix 6/8.

8 x 6 = 48

6 x 6 = 36.

2 x 24 = 48.

5 x 24 = 120 or 12

now we have 12/48 and 36/48.

We can subtract now!

Hope this helped for problems like this.

I=$26.24, P=$500, T=18 months the annual interest rate is

NeX [460]

A = $2,861.60

I = A - P = $2,361.60

Equation:
A = P(1 + rt)

Calculation:
First, converting R percent to r a decimal
r = R/100 = 26.24%/100 = 0.2624 per year.

Solving our equation:
A = 500(1 + (0.2624 × 18)) = 2861.6
A = $2,861.60

The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 26.24% per year for 18 years is $2,861.60.

Tyler fills up his tank with 12 gallons of gas. If one trip, on average,takes 1/2 gallon of gas, how many trips will the Tyler b

Bingel [31]

24
Since each trip takes half a gallon of gas, you divide the amount of gas by how much per trip.
That gives you 24 trips he can make with the gas.

Which of the following would best represent a cosine function with an amplitude of 3, a period of pi/2 , and a midline at y = –4

Grace [21]

To transform the function $f(x)= cos(x)$ to have the amplitude of 3, we need to multiply the constant 3 to the function f(x), so we have $y=3f(x)$

To transform the function $f(x)=cos(x)$ to have the midline $y=-4$ we need to subtract $f(x)$ by 4, so we have $y=f(x)-4$ ,

To transform the function $f(x)=cos(x)$ to have period of $\frac{ \pi }{2}$ , we need to divide the original period $2 \pi$ by 4, so we have $y=f(4x)$ . Note that it is the $4x$ gives the effect of dividing the points on x-axes by 4 and the period is read on x-axes

Hence, the full transformation is given $y=3f(4x)-4$ which is the last option
