What is the solution to this inequality?
−4x − 8 > −20
Question 7 options:
x > −3
x < −3
x > 3
x <3
Answers
Answer:
[tex]\boxed{\sf{D. \quad x < 3}}[/tex]Step-by-step explanation:
It is necessary to isolate the term of x from one side of an inequality to find its solution.
-4x-8>-20First, add by 8 from both sides.
[tex]\sf{-4x-8+8 > -20+8}[/tex]
Solve.
-20+8=-12
Rewrite the problem down.
[tex]\sf{-4x > -12}[/tex]
Multiply by -1 from both sides.
(-4x)(-1)<(-12)(-1)
Solve.
Multiply the numbers from left to right.
(-12)(-1)=12
4x<12
Divide by 4 from both sides.
4x/4<12/4
Solve.
Divide the numbers from left to right.
12/4=3
x<3
Therefore, the correct answer is D. x<3 (last option).I hope this helps you! Let me know if my answer is wrong or not.
Answer:
Option D.
Why is this the case, though?These equations prove it true.
[tex]-4 * 2 - 8 = -16 > -20[/tex]
[tex]-4 * 1 - 8 = -12 > -20[/tex]
The only reason these two equations are correct, is because on the number line it shows: Any negative number further to the right than the last negative number is greater than that number.

When you simplify -6+4q+(-6q), you'll end up with -2q-6, which isn't present between the two choices.
-6(q+1)-4q = -10q-6, so that can't be the answer
2(q-3) = 2q - 6. But the 2q isn't negative, so therefore, this isn't the answer either
Therefore, the answer is C: None of the above

The asteroids are mostly found in the broad space between Mars and Jupiter, a region of the solar system called the asteroid belt. Asteroids are too small to be seen without a telescope; the first of them was not discovered until the beginning of the nineteenth century.
Discovery and Orbits of the Asteroids
In the late 1700s, many astronomers were hunting for an additional planet they thought should exist in the gap between the orbits of Mars and Jupiter. The Sicilian astronomer Giovanni Piazzi thought he had found this missing planet in 1801, when he discovered the first asteroid (or as it was later called, “minor planet”) orbiting at 2.8 AU from the Sun. His discovery, which he named Ceres, was quickly followed by the detection of three other little planets in similar orbits.

B. 1/5 divide by 3
C. 1/5 divide by 4
D. 1/5 divide by 5
Answers
Answer:
C. 1/5 divide by 4
Step-by-step explanation:
When you divide two fractions, you multiply the first fraction by the reciprocal of the other one. To find the reciprocal of the second fraction, yo just have to switch the value of the numerator and denominator (i.e. 4/1's reciprocal is 1/4).
Another important thing to note is that 1/5 x 1/4 is 1/20 because you multiply straight across numerators and denominators.
Now that we have some back ground information, let's which expression leads to 1/20!
A:
1/5 x 2/11/5 x 1/21/10Incorrect Answer ChoiceB:
1/5 x 3/11/5 x 1/31/15Incorrect Answer ChoiceC:

Given Equation :
[tex] \\ {\longrightarrow \qquad{ \sf{5x-10=3x+2}}} \\ \\ [/tex]
Subtracting 3x from both sides we get :

What's Ali's average speed on her walk to school if she walks halfway at 2mph and runs the rest of the way at 7mph?
Answers
Answer:
s = 28/9
Step-by-step explanation:
d/(7 x 2) + d/(2 x 2) = d/s
d/14 + d/4 = d/s
18d/56 = d/s
18/56 = 1/s
s = 28/9
The average speed is 28/9.
What is Average speed?Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.
Example
Using the average speed formula, find the average speed of Sam, who covers the first 200 kilometers in 4 hours and the next 160 kilometers in another 4 hours.
To find the average speed we need the total distance and the total time.
Total distance covered by Sam = 200Km + 160 km = 360 km
Total time taken by Sam = 4 hour + 4 hour = 8 hour
Average Speed = Total distance covered ÷ Total time taken
Average Speed = 360 ÷ 8 = 45km/hr
The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:
Average Speed Formula:
Average Speed = Total distance covered ÷ Total time taken
Given:
halfway at 2mph and runs the rest of the way at 7mph
d/(7 x 2) + d/(2 x 2) = d/s
d/14 + d/4 = d/s
18d/56 = d/s
18/56 = 1/s
s = 28/9 mph
