translate into an algebraic expression: 120 is decreased by d% and increased by 25%. what is the result

s2008m [1.1K]

Answer:

150(1-x)

Step-by-step explanation:

120 is decreased by d%

Let x = d%

120 - 120*x

120(1-x)

Then it is increased by 25%

(120 (1-x)) +(120 (1-x))*.25

(120 (1-x)) +(30 (1-x))

150(1-x)

Solve for x, show your work:<br> 3/5 =x/30

Tpy6a [65]

Answer:

$\frac{3}{5} = \frac{18}{30}$

Step-by-step explanation:

To solve this proportion, we will divide the two given denominators.

Now, we have: 30 ÷ 5 = 6

Next, we will multiply the given numerator by the quotient: 3 × 6 = 18

So, our final proportion will have to be:

$\frac{3}{5} = \frac{18}{30}$

If f(x) = 2x2 + 5x - 8 and f(x) = -10,<br> which of the following could be a<br> value for x?<br> -2

alexdok [17]

Answer:

x = -2 or x = -1/2

Step-by-step explanation:

We can just set up an equation where the quadratic is equal to -10, and then solve the equation:

$2x^2+5x-8=-10\\2x^2+5x+2=0\\\\$

Now, factor:

$(2x+1)(x+2) = 0\\x=-2 \text{ or } x=-1/2$
