-6 is a solution for -4x > 16
Answer:
True
Step-by-step explanation:
-4x > 16
Divide each side by -4, remembering to flip the inequality since we are dividing by a negative
-4x/-4 < 16/-4
x < -4
-6 is less than -4 so -6 is a solution to the inequality
Answer: True
Step-by-step explanation:
It equals 24>16
Brayden is making dumplings. If he uses 3 5
a cup of dough for each dumpling, how much dough does Brayden need to make 9 dumplings?
WELL, considering 3 5 is three fifths, then all you gotta do is multiply 3/5 by 9 to get your answer. Your answer, in decimals, is 5.4!
Hope this helps, if not, comment below please!!!
( ps: if you want me to convert 5.4 to fraction, just let me know! )
Answer:
27/9 or 5 2/9
Step-by-step explanation:
1. If one dumpling is worth 3/5 just multiply the 3 (numerator) by the amount of dumplings Brayden wants to make (9) so you would get the equation 3(9) and the answer is 27.
2. 27 is now the new numerator so put it over 5: 27/5. 27/5 is an improper fraction so the proper way of putting it would be 5&2/9.
3. Brayden needs 27/5 or 5&2/9 cups of dough to make 9 dumplings.

For a rotation r ( x ∘ , P ), which of the following is not true?
For a pre-image point P, m∠PAP′=x degrees.
For the a preimage point A, PA=PA′
The expression A=B r ( x ∘ , P ) A = Br ( x ∘ , P ) A = Br ( x ∘ , P ) A = Br ( x ∘ , P ) A = B means that when point A is rotated x° around point P its image is located at point B
The transformation rotates every point in the preimage x° about a point P
Answer:
For a pre-image point P, m∠PAP′=x degrees.

A walli can be built by 6 men working for 8 hours per day in 5 days. How many days will it take 4 men to build if they work only 5 hours per day.
(show your working)
Answer:
A wall can be built by 6 men working 8*5*6=240 hours.
If 4 men works 5 hours a day, they work 20 hours/day.
It will take them 240 hours /20 hours = 12 days

What is the slope of a line parallel to the line whose equation is 9x – 3y = 81. Fully
reduce your answer.
Answer:
Ok so right now that is in standard form (Ax+by=C) and we want to get this into y=mx+b form so that we can easily identify the slope. To do that we need to get y alone by folowing these steps:
9x-3y=81
9x-9x-3y=81-9x (in this step we are just getting rid of the x's from the left side so we can get y alone but since we subtract x from that side we need to subtract the same amount of x's on the other)
-3y=81-9x
-3y/-3=81-9x/-3 (finally to get y alone we need to divide by a -3. This is because any negative number multiplied or divided by another negative will give us a positive. If we divide by 3 then y will be negative which is incorrect. We have to divide by -3 on each side)\
y=81-9x/-3 -----> y=-27+3x ( in this part we have to divide everything on the right side of the equation by -3 as we did on the left side. 81/-3 = -27 and -9x/-3 = +3x.
our new equation is y=-27+3x although the proper form is y=mx+b.
all we need to do now is flip the 3x and -27 for this equation to match y-mx+b form. M in the equation represents the slope of an equation.
y=-27+3x---> y=3x-27
in this equation 3 is m and m represents the slope. For an line to be parralel to one another they must have the same slope. Therefore the slope of a line parallel to that equation is 3.
Step-by-step explanation:
The Slope of a line parallel to the line whose equation is 9x – 3y = 81 is 3.
What is the Slope of a line?A slope of a line is the change in y coordinate with respect to the change in x coordinate.
Given that the slope of a line parallel to the line whose equation is
9x – 3y = 81
Reducing the Equation in form of y = mx + c, where m is the slope,
9x - 3y = 81
3y = 9x - 81
y = 3x - 27
Since, two line when parallel have equal slope, so the slope of the given line is 3.
Hence, The Slope of a line parallel to the line whose equation is
9x – 3y = 81 is 3.
