How to solve 3x+12-6x<-9

Mathematics
1 answer:
FinnZ [79.3K]3 years ago
3 0

Answer:

x > 7

Step-by-step explanation:

Group the common factors, which are 3x and -6x, so it looks like:

3x - 6x + 12 < -9

-3x + 12 < -9

Subtract 12 from both sides:

-3x < -21

Divide everything by -3 to get your answer. Don't forget when dividing by a negative number, you have to flip the sign:

x > 7

F) 16 - p = 12 <br> g) 18 - 2p = 6<br> h)p2+ 4 = 9 <br> i)p4- 3 = 1<br> **MUST SHOW YOUR WORK**
mestny [16]
f) 16 - p = 12 minus 12
4 - p = 0 plus p
p = 4
g) 18 - 2p = 6 divide by -2
-9 + p = -3 plus 9
p = 6
h) p x 2 + 4 = 9 divided by 2
p + 2 = 4.5 minus 2
p = 2.5
i) p x 4 - 3 = 1 plus 3
p x 4 = 4 divided by 4
p = 1

PLEASE HELP ME: the ratio of cars to trucks on a highway at any given time is 12 to 8. If there are always more than 105 cars on
andre [41]

Answer:

70

Step-by-step explanation:

First, set up the ratio of c:t, which is 12:8. Then set up your new ratio of c:t, which is 105:?. The way I find the easiest is to divide 105 by 12, which is 8.75, then multiply that by 8, which is 70. To check if it's right, just divide 12 by 8, and 105 by 70, and if they're the same number, you've got it right.

Ps. I'm guessing you meant to ask the minimum number of trucks, not cars.
