5 0

Answer:

Step-by-step explanation:

(x-7) * -5 = 60

-5x + 30 = 60

5x  = 60 - 30

x = 30/-5

so x = -5

6a+4=61/3+4<br> I don’t know what I’m doing wrong because I keep getting 10 1/3
Vlad1618 [11]

Answer:

a = 3 7/18 or 3.388889

Step-by-step explanation:

First, you want to get the a by itself, so you would subtract 4 from the left side of the equals sign.

6a + 4 = 61 / 3 + 4

    -4                   -4

6a = 61 / 3

By doing that, they cancel each other out, so you are left with

6a = 61 / 3

Then you want to get a by itself, so you divide 6 from both sides.

6a / 6 = 61 / 3  /  6

Remember that 6 can also be written as 6/1

Remember that dividing a fraction is multiplying the reciprocal.

6a / 6 = 61 / 3  /  6 / 1

When dividing fractions remember to Skip the first fraction, Flip the second fraction, and Multiply the two fractions together.

61 / 3      x        1 / 6

skip   multiply   flip

Multiply across the top, and across the bottom.

61(1) and 3(6)

Then you get

61 / 18

So a = 61 / 18

If you want to convert that to a mixed number, it would be 3  7 / 18

If you want that in a decimal, it would be 3.388889

What is the solution of x^2+x-6/x-7&lt;0
Ivenika [448]

Answer:

the solution of the equation is: (-\infty,-3)\cup (2,7)

Step-by-step explanation:

we are given the expression as \frac{x^2+x-6}{x-7}

=\frac{(x-2)(x+3)}{(x-7)}

we will use the number line rule for inequalities(first by making the coefficients of x positive then taking the roots on the number line and depending on the sign in the equation we start taking alternate signs and depending on the inequality take the desired region)

we get (-\infty,-3)\cup (2,7).

density is the ratio of mass to volume density = mass/volume compare the density of different liquids with the same volume the l
bija089 [108]

Here, we are required to compare the density of different liquids with the same volume

Since density is the ratio of mass to volume, different liquids for example, kerosene and water if they have the same volume, will have different masses.

This is due to the difference in their densities.

Therefore, according to the statement in the question above;

While comparing the density of Liquids with the same volume, the liquid with the greatest density is heavier(more quantity of matter per unit volume) while the liquid with the least density is lighter( less quantity of matter per unit volume).
