Answer:

x = 3/10

Step-by-step explanation:

−1/2 − (−4/5) = x

First, switch sides.

x = −1/2 − (−4/5)

You are subtracting a negative number. Subtracting a negative number means add a positive number.

x = -1/2 + 4/5

Now you are adding two fractions, so you need a common denominator. The LCD of 2 and 5 is 10.

x = -5/10 + 8/10

x = 3/10

your answer might be 1.1

Step-by-step explanation:

You see you have to divide it so it will be -1 divided by 2-(- 4 divided by5)=x so if we do x - those all our answer will be 1.1 your welcome I hope that helps

REN fine six peanuts, four raisins, 3 cranberries, and 5 chocolate chips in a handful of trail mix. For every 9 pieces in Ren's

tankabanditka [31]

Answer:

2 raisins.

Step-by-step explanation:

Let x represent total number of required ingredient.

We have been given that Ren finds 6 peanuts, 4 raisins, 3 cranberries, and 5 chocolate chips in a handful of trail mix. We are asked to find of which ingredient Ren will have 2 pieces for a total of 9 pieces.

First of all, we will find total number of ingredients by adding each ingredient as:

$\text{Total number of ingredients}=6+4+3+5$

$\text{Total number of ingredients}=18$

Now, we will use ratio to solve for our given problem as:

$\frac{\text{Required ingredient}}{\text{Total ingredient}}=\frac{2}{9}$

$\frac{x}{18}=\frac{2}{9}$

$\frac{x}{18}\cdot 18=\frac{2}{9}\cdot 18$

$x=\frac{2}{1}\cdot 2$

$x=4$

Since there are 4 raisins, therefore, for every 9 pieces in Ren's handful of trail mix there are 2 raisins.

If g(x) = 3x + 2 and h(x) = 9x2 + 12x + 6, find a function f such that f ○ g = h

Virty [35]

F(g(x)) = f(3x+2) = h(x)=9x^2+12x + 6

Note that (3x+2)^2 = 9x^2 + 12x + 4, which is almost, but not quite, equal to h(x).

Let's experiment. What if f(x) = x^2 + 2?

Then f(3x+2) = (3x+2)^2 + 2 = 9x^2 + 12x + 4 + 2 = 9x^2 + 12x + 6, which is the same as the given h(x).

Thus, f(x) is x^2 + 2.

- 6x+4=-2 algebra question

QveST [7]

You need to get x= something.

To do this, you -4 on both sides to leave you with just an x value on the left. This gives -6x=-6

Then you need x on its own, so you divide both sides by -6.

-6/-6= 1, so x=1
