You can also write it as 45+28.
In English, a double negative is when two negative words are used in the same sentence.
A double negative in Math is when you have a scenario like this. For example, 1-(-1) is also equal to 1+1.
So 45+28 is 73.

PLEASE ANSWER At a basketball game, 75% of people attending were supporting the home team, while 25% were supporting the visiting team. If 750 people attending the game supported the home team, what was the total number of people attending the game?
75% = 0.75
750 people / 0.75 = 1,000 people
There were 1,000 total people attending the game
Answer:
1,000 people
Step-by-step explanation:
At a basketball game, 75% of people attending were supporting the home team, while 25% were supporting the visiting team. If 750 people attending the game supported the home team, the total number of people attending the game was 1,000 people.
75% = 3/4 or 0.75
25% = 1/4 or 0.25
We need to find what 25% is.
75/3=25
75% = 0.75
750 people / 0.75 = 1,000 people
Therefore, there were 1,000 people at the game.

Larry ran 4/5 of the way around the track before slowing down to a walk. What percent of the track did he run? *
Answer:
80%
Step-by-step explanation:
4 divided by 5 = 0.8
0.8 x 100 = 80%
The percentage Larry ran around the track = 80%
He ran 4/5 of the way around the track before slowing down for a walk.
This means he ran 4 parts of the whole 5 parts of the track. He walks the remaining 1 part around the track.
Therefore, the percentage he ran can be calculated below
% he ran the track = 4 / 5 of 100
% he ran the track = 4 / 5 × 100 = 400 / 5 = 80%
The percentage he ran around the track = 80%

Find the value of x and YZ if Y is between X and Z. Draw, label, set up the equation and solve each for :
4. XY = 5x, YZ=x, and XY=25
5. XY = 12, YZ=2x, and XZ = 28
7. XY=2x + 1. YZ = 6x, and XZ=81
6. XY = 4x. YZ=3x, and XZ = 42
Step-by-step explanation:
We need to find the value of x for all problems if Y is between X and Z.
For all cases, XZ = XY+YZ
4. XY = 5x, YZ=x, and XZ=25
Putting all values
25 = 5x + x
25 = 6x
[tex]x=\dfrac{25}{6}[/tex]
5. XY = 12, YZ=2x, and XZ = 28
28 = 12 + 2x
x = 8
6. XY = 4x. YZ=3x, and XZ = 42
XZ = XY+YZ
42 = 4x + 3x
42 = 7x
x = 6
7. XY=2x + 1. YZ = 6x, and XZ=81
XZ = XY+YZ
81 = 2x + 1 + 6x
80 = 8x
x = 10

witch is greater -6 or 7
Answer:
7
Step-by-step explanation:
Very easy problem once you understand "negative numbers."
"-6" is a negative number. A negative number is a number below zero. You'll know if a number is negative because it has a minus symbol (this symbol - ) before it. -6 is a negative number and below zero. 7 is a number above zero so therefore 7 is a greater number.
Here's another thing about negative numbers. Even though the number may look "bigger" (for example -7) is actually a SMALLER number than -6. The more "negative a number is" the smaller it is. Hope this helps and have a nice day!

Almonds cost $5.20 per pound Raisins cost $2.75 per pound Priya spent $11.70 of buying almonds & raisins Equation: 5.20+2.75=11.70 How many pounds of raisins did she buy if she bought the following amounts of almonds: •2 pounds of almonds •1 pound of almonds •0.64 pounds of almonds • “a” pounds of almonds
Answer:
If she bought 2lbs of almonds, she bought 0.4lbs of raisins. If she bought 1lb of almonds, she can buy up to 2.36lbs of raisins. If she bought 0.64lbs of almonds, she can buy up to 1.9lbs of almonds.
Step-by-step explanation:
The total pounds of raisins bought is 0.47 pounds.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that Priya bought 0.47 pounds of raisins, Almonds cost is $5.20 per pound and Raisins cost $2.75 per pound.
The Total cost of almonds purchased = $5.20a
The Total cost of raisins purchased = $2.75r
Where:
a = total pounds of almonds bought
r = total pounds of raisins bought
The Total amount spent on raisins and almonds;
5.20a +2.75r = 11.70
If 2 pounds of almonds are bought;
5.20(2) +2.75r = 11.70.
10.40 + 2.75r = 11.70
Combine similar terms;
2.75r = 11.70 - 10.40
2.75r = 1.30
Now Divide both sides of the equation by 2.75
r = 0.47 pounds
Hence, the total pounds of raisins bought is 0.47 pounds.
