Answer:
Treat the lesser than sign as an equal sign. What you do to one side, you do to the other. Isolate the variable x. Do the opposite of PEMDAS.
PEMDAS = Parenthesis, Exponents ( & roots), Multiplication, Division, Addition, Subtraction.
<u>Solve -6x + 14 < -28</u>
First, subtract 14 from both sides:
-6x + 14 (-14) < -28 (-14)
-6x < -42
Next, divide -6 from both sides to isolate the variable x. Note that when you divide (or multiply) by a negative number, you must flip the greater than or less than sign.
(-6x)/-6 < (-42)/-6
x > (-42)/(-6)
x > 7
x > 7 is your answer.
<u>Solve 3x + 28 < 25</u>
First, subtract 28 from both sides.
3x + 28 (-28) < 25 (-28)
3x < -3
Isolate the variable x. Divide 3 from both sides. Note that because you aren't dividing by a negative number (rather a positive 3), you do not flip the sign.
(3x)/3 < (-3)/3
x < (-3)/(3)
x < -1
x < -1 is your answer.

About 390 km because you drive 130 km per hour so 130 times 3 is 390
Answer:
$75 I think. Not 100% sure but like 95% sure :)
Answer:
-100 + x = 40
Step-by-step explanation:
According to the question:
Tyler's original height = -100 feet
Tyler's final height = 40
X to represent change in elevation
As initial + change = final, the equation would be:
-100 + x = 40

I wasn't sure about my answer, so used the gauthmath app.
X=number of miles
$329=$175+$0.70x
329-175=.70x
154=.70x
154/.70=x
220miles =x
