Distribute 34 in the parentheses which gives you 170f-102=38
add 102 to 38 giving you 170f=140
then divide 170f/140 which gives you about 1.2f

What value of x makes the following equation true?<br> 15+3x=3(2−2x)

Alinara [238K]

Answer:

$\boxed {x = -1}$

Step-by-step explanation:

Solve for the value of $x$ :

$15 + 3x = 3(2 - 2x)$

-Use <u>Distributive Property</u>:

$15 + 3x = 3(2 - 2x)$

$15 + 3x = 6 - 6x$

-Take $6x$ and add it to $3x$ :

$15 + 3x + 6x = 6 + 6x - 6x$

$15 + 9x = 6$

-Subtract both sides by $15$ :

$15 - 15 + 9x = 6 - 15$

$9x = -9$

-Divide both sides by $9$ :

$\frac{9x}{9} = \frac{-9}{9}$

$\boxed {x = -1}$

Therefore, the value of $x$ is $-1$ .

The surface area of the prism will be given by:
SA=2(L×W)+2(L×H)+2(H×W)
SA=2(12×5)+2(12×9)+2(5×9)
SA=120+216+90
SA=426m²

If you drive 300 miles and do 70 per hour how much minutes does it take

dangina [55]

Answer: well I'm sorry I can't help that much but 300÷70(per hour)=4.28571428571 (Yes I did the math in my head) but it would be an estimate of 4 or 5 minutes. If I helped that's the least I can do. Your welcome! Anytime!!

If c(x)=5/x-2 and d(x)=x+3, what is the domain of (cd)(x)?

pickupchik [31]

Answer:

The domain is all Real x except x = 2 .

Step-by-step explanation:

(cd)(x) = ( 5 / x-2) * x+3

= 5(x+3)/(x-2)

The domain is all Real x except x = 2 .

(because when x = 2 (cd)(x) is undefined).
