What is 5 2/5 subtract 2 1/15?

2 answers:

7 0

5 2/5 would be converted to 5 6/15. you would then subtract the numerators and the whole numbers, giving you 3 5/15, which simplifies to 3 1/5

The answer is: 1 and 1/3

5 2/5- 2 1/15

To get the answer, we first must make both denominations the same
(Denominators are the numbers at the bottom of the fraction)

To do this we can multiply 2/5 times 3/3 in order to have the number be equal to it’s original value.
It would now look like this:

6/15

We then just combine it to the remaining numbers. The problem should look like this:

5 6/15- 2 1/15=

3 1/3

If ABC=DEF and MNO=PQR, then ABC=PQR by the transitive property.

zavuch27 [327]

Answer:

B. False

Step-by-step explanation:

There is not enough information to make that conclusion. The two statements are completely unrelated, so the transitive property cannot be used. None of the given statements say that ABC is congruent to MNO or PQR. That means that nothing can be assumed about DEF. To use the transitive property you would need proof that ABC=MNO or ABC=PQR. But neither of those statements are there so the answer is false.

Tiffany and Dion are having a walking race. The equation and graph show the distance each person is from the starting line,

satela [25.4K]

Answer:

Step-by-step explanation:

Tiffany's distance is defined by the equation,

d = 2.5t

Here, d = distance of Tiffany from the starting line

t = time

a). d = 2.5t

$\frac{d}{t}=2.5$

Tiffany's rate = 2.5 yards per second

b). Since, slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Therefore, slope of the line passing through two points (0, 10) and (10, 35)

= $\frac{35-10}{10-0}$

= 2.5 yards per second

Dion's walking rate = 2.5 yards per second

Equation that defines the distance of Dione,

d = mt + b

Here, m = rate of the walking by Dione

b = y-intercept

Hence, equation will be,

d = 2.5t + 10

c). If d = 60 yards

For Tiffany,

d = 2.5t

60 = 2.5t

t = 24 seconds

For Dion,

d = 2.5t + 10

60 = 2.5t + 10

2.5t = 50

t = 20 seconds

Therefore, Dion will take less time and finish first.

Ava borrowed some money from her friend in order to help buy a new video game system. Ava agreed to pay back her friend $2 per w

nydimaria [60]

We know that Ava is paying $2 dollars per week so if L is the money that she owes and t is the number of weeks, and I is the initial debt so we can write an equation like:

$L=I-2t$

Now we can replace the info we have to find the value of I so:

$10=I-2(5)$

and we solve for I

$\begin{gathered} I=10+10 \\ I=20 \end{gathered}$

So the final equation will be:

$L=20-2t$

A company invests a total of $40 comma 000 of surplus funds at two annual rates of interest: 5% and 6one half %. It wishes a

vampirchik [111]

Suppose the company invests x of their surplus in the 5% rate (and thus 40000-x has 6.5%). Then we have that 5%*x+(40000-x)6.5%=6.25%*40000.
We have that solving this, 5%* x+40000*6.5%-6.5%*x =6.25%* 40000 Accumulating terms, 1.5%*x=0.25%*40000 x=40000/6= 6666.67$. We see that if we invest 6666.67$ at 5%, we get exactly the given rate. If we invest more, we obviously get less. Hence, we have that the company has to invest at 6.5% more than 40000-6666.67=33333.33$
