20 + (-16)
20 - 16 = 4
5 + (-16)
5 - 16 = -11

how would you solve -5(x - 1) = 40
Answers
-5x+5=40
you would then subtract 5 from both sides, so you would get:
-5x=35
you would then divide by -5 on both sides, so you would get:
x=-7
Answer:
x = -7
Step-by-step explanation:
Apply the distributed property: -5x - -5 = 40Simplify: -5x + 5 = 40Subtract 5 from each side, so it now looks like this: -5x = 35Divide each side by -5 to cancel out the -5 next to x. It should now look like this: x = -7I hope this helps!
Jeff is 4 times older than his daughter. Five years ago he was 9 times older than his daughter. Write an algebraic equation to determine the age of his daughter.
Answers
Jeff is 32, His Daughter is 8
The relationship between the age of Jeff and his daughter can be summarized by the following systems of equation:
Jeff's age = x
Jeff's Daughter's age = y
x=4y jeffs age is equal to his daughters times four
x-5=9(y-5) jeffs age minus five is equal to his daughters age minus five as well times 9
Combining these equations will get us x=32, y=8.
The algebraic equation 4D - 5 = 9D - 45. The current age of Jeff's daughter is 8 years old.
Let's represent the current age of Jeff's daughter as "D" and Jeff's current age as "J".
According to the problem:
Jeff is 4 times older than his daughter, so we can express this relationship as:
J = 4D
Five years ago, he was 9 times older than his daughter. This means that their ages five years ago are:
(J - 5) = 9(D - 5)
Now, we can write the algebraic equation to determine the age of his daughter (D):
(J - 5) = 9(D - 5)
Since we already know that J = 4D, we can substitute this into the equation:
(4D - 5) = 9(D - 5)
Now, we can solve for D, which represents the current age of Jeff's daughter. Expanding equation:
4D - 5 = 9D - 45
Next, move the variables to one side and the constants to the other side of the equation:
4D - 9D = -45 + 5
Combine like terms:
-5D = -40
Finally, solve for D:
D = -40 / -5
D = 8
Therefore, the current age of Jeff's daughter is 8 years old.

5x+3y=18 and 3x-3y=15 solve for y and x using elimination method
Answers
Answer:
x = 4.125 or [tex]4\frac{1}{8}[/tex]
y = -0.875 or [tex]-\frac{7}{8}[/tex]
Step-by-step explanation:
5x + 3y = 18
3x - 3y = 15
3y and -3y can be cancled out becuase + and - cancel out and they both have 3y in them. We don't have to switch any signs in this case. You can just add them all exept 3y and -3y becuase they will be canceled out.
8x = 33
x = 4.125
Now we know what x is. We need to figure out what y is now. To figure out y chose an equation from the problem and plug in the x value. Lets chose 3x - 3y = 15.
3(4.125) - 3y = 15
12.375 - 3y = 15
-3y = 2.625
y = -0.875
Now we know what y is. I hope this helps :)
ASAP PLZZZZZZZZ HELP _____________ waves need a medium to travel, but _____________ waves do not.
Group of answer choices
sound; light
sound; electrical
light; sound
electrical; light
Answers
brainliest is appreciated!
Answer:
Sound waves need a medium to travel, but light waves do not.
Step-by-step explanation:
Sound waves need a medium to travel because they cannot travel through a vacuum. This is because sound travels by producing vibration in the molecules of the medium surrounding it and there are virtually no molecules in a vacuum. Light doesn't need a medium through which to travel because the speed of light is experimentally constant.
if you reflect any shape across the x-axis and then rotate it 90 degrees clockwise about the origin, do you get the same results as if you reflect it across the y-axis and then rotate it 90 degress counterclockwise about the origin? what does this mean?
Answers
Yes, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise direction around the origin to achieve the same results as a shape reflected across the y-axis and rotated in a counterclockwise direction. This implies that these two transformational sequences are similar.
What is reflection in Mathematics?A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

A store sells two kinds of candles,scented candles and unscented candles. The candles burn at different rates which kind of candle burns more in one hour? How much more per hour? The scented one burns 1/8inch an hour 1/4 hour and the unscented one burns 1/9 inch in 1/3 hour. SHOW WORK!!!!
Answers
Step-by-step explanation:
The first thing we must observe is that the hourly rate for each candle is:
scented candles:
(1/12) / (20/60)
Simplifying:
= (1/12) / (10/30)
= (1/12) / (5/15)
= (1/12) / (1/3)
= (3/12)
= (1/4) inches / hour
Unscented candles:
(1/6) / (30/60)
Simplifying:
= (1/6) / (15/30)
= (1/6) / (3/6)
= (1/6) / (1/2)
= (2/6)
= (1/3) inches / hour
Answer:
The unscented candles burn faster at a rate of:
(1/3) inches / hour.
Answer:
