We first write the word in math as x+3/5 = 5/7. Now we cross multiply our fractions and rewrite them with the LCD of 5 and 7. Our equation now looks like x + 21/35 = 25/35. We simplify our equation by subtracting 21/35 from both sides to get x = 4/35. 4/35 is already in lowest terms so it is our answer.

Answer: The required value of x is $\dfrac{4}{35}.$

Step-by-step explanation: Given that the sum of x and $\dfrac{3}{5}$ is $\dfrac{5}{7}.$

We are to find the value of x.

According to the given information, the equation can be written as follows :

$x+\dfrac{3}{5}=\dfrac{5}{7}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

The solution of equation (i) is a follows :

$x+\dfrac{3}{5}=\dfrac{5}{7}\\\\\\\Rightarrow x=\dfrac{5}{7}-\dfrac{3}{5}\\\\\\\Rightarrow x=\dfrac{25-21}{35}\\\\\\\Rightarrow x=\dfrac{4}{35}.$

Thus, the required value of x is $\dfrac{4}{35}.$

Best answer gets brainliest!<br><br> What are some equivalent expressions of 6(m + 2 + 7m)?

bezimeni [28]

Answer:

See Explanation

Step-by-step explanation:

To write an equivalent expression, we can combine like terms. So m +7m is 8 and we get 6(8m+2).

Here are a few others:

48m+12

6(m+m+m+m+m+m+m+m+2)

3(16m+4)

6m+12+42m

6m+6m+6m+6m+6m+6m+6m+6m+2

and the list goes on...

URGENT I HAVE ALMOST 0 TIME LEFT I NEED LAST MINUTE HELP

Answer:

The zeros are the points where the parabola intercepts the x-axis.

$\sf x = 7 \implies x - 7 = 0$

$\sf x = 1 \implies x - 1 = 0$

$\sf \implies y = a(x - 7)(x - 1)$ where a is some constant

If the parabola passes through point (3, 4) then:

$\sf \implies a(3 - 7)(3 - 1) = 4$

$\sf \implies a(-4)(2) = 4$

$\sf \implies -8a = 4$

$\sf \implies a = -\dfrac12$

So the equation of the parabola is:

$\sf y = -\dfrac12(x - 7)(x - 1)$

Or in standard form:

$\sf y = -\dfrac12x^2+4x-\dfrac72$
