Step-by-step explanation:
With Multiplication and Division you just carry out normal Multiplication and Division. If the equation has an EVEN number of negative signs the answer will always be positive (the sign cancel each other out). In turn if there is an ODD number of negative signs the answer will always be negative,... (with Addition and Subtraction it is different but with Multiplication and Division working out problems works in this way,...)
1 = 96 (even number of negative signs,... (in the whole equation))
2 = -4 (odd number of negative signs)
3 = -60
4 = -176
5 = 44
6 = -76
7 = -64
8 = 306
9 = 64
10 = 48
11 = 24
12 = 48
13 = -7 (do the division like you normally would except now just add the neg sign when appropriate (in this case there is 1 neg sign so answer is neg))
14 = 16
15 = -7
16 = 2
17 = -4
18 = 13
19 = 5 (do the parenthesis first (order of operations))
20 = 5 (do the parenthesis first (order of operations))
OKAY,... I think that does it,... Best of luck! Hope that helps,... Chow,...!

You are so smart. 5 - (-7) = 5+7 which = 12. 12/3 is 4.
Answer:
[tex] \boxed{x = -4} [/tex]
Step-by-step explanation:
This drawing illustrates the
equation: -3x – 7 = 5.
Since:
(-x + -x + -x) + (-1 + -1 + -1 + -1 + -1 + -1 + -1) =
(1 + 1 + 1 + 1 + 1) → (-3x) + (-7) = (5) →
-3x – 7 = 5.
To reduce the equation and find x:
[add 7 to both sides to isolate the constant term on the right side]
-3x – 7 + 7 = 5 + 7 →
-3x = 12 →
[divide both sides by -3 to cancel out the coefficient of -3 in -3x to get x]
-3x / -3 = 12 / -3 →
x = -4

3/10 of the members of a tennis club are men. 5/6 of these men are right handed. work out the fraction of members of the tennis club who are right handed
=============================================================
Explanation:
Let's say there are 60 members at the club. I picked this value since 10*6 = 60, which is the product of the denominators. This will help give us whole numbers in the steps shown below. You can pick any number you want for the club size.
Since we have 60 members and 3/10 of them are men, this means (3/10)*60 = 18.
So there are 18 men at this club.
--------------
Next, we're told that 5/6 of the men are right handed. So (5/6)*18 = 15 men are right handed.
Lastly, we divide that last result (15) over the total number of club members (60) and we end up with 15/60 = (1*15)/(4*15) = 1/4
Therefore, 1/4 of the members are men who are right handed.
Unfortunately, we don't have enough data to be able to say anything about what fraction of the women are right handed.
--------------
Note that:
(3/10)*(5/6) = (3*5)/(10*6) = 15/60 = 1/4
which is an alternative pathway to the solution.

The box plot represents the distribution of the number of points scored by a cross country team at 12 meets.
Did the cross country team ever score 30 points at a meet?
We cannot tell if the team scored exactly 30 points at a meet.
The information which could be inferred from a boxplot include :
The minimum = lower position of the whisker = 22The maximum value = upper position of the whisker = 42The median = vertical line inbetween the box = 34The lower quartile (Q1) = starting point of the box = 33Upper quartile (Q3) = end point of the box = 38
Interquartile range = Q3 - Q1 = (38 - 33) = 5
Hence, one cannot determine if the cross country ever scored 30 points in a meet.
However, we can deduce that the country scored above or below 30 points in a meet.

how to solve 5{2p-4(p+5)}=25
Answer:
this is the solution of your questions don't mind my handwriting because I write it fast ⏩
Step-by-step explanation:
s
To solve the equation 5{2p-4(p+5)}=25, simplify the expression inside the curly brackets, combine like terms, and solve for the variable p. The solution is p = -12.5.
The given expression is 5{2p-4(p+5)}=25.
We need to find the solution of p.
Apply distributive property:
5(2p-4p-20)=25
10p-20p-100=25
-10p-100=25
Add 100 on both sides:
-10p=25+100
-10p=125
Divide both sides by -10:
p=-125/10
p=-12.5
Hence, the value of p is -12.5.

Step-by-step explanation:

Hello there!
We are given the equation below:
[tex] \displaystyle \large{5(2x - 3) = - 4(x + 4) - 13}[/tex]
First step is to distribute 5 and -4 in the expression.
[tex] \displaystyle \large{10x- 15= -4x - 16- 13}[/tex]
Add both sides by 4x so we can move -4x to add like term.
[tex] \displaystyle \large{10x- 15 + 4x= -4x + 4x - 16- 13} \\ \displaystyle \large{10x- 15 + 4x= - 16- 13}[/tex]
Then add both sides by 15.
[tex]\displaystyle \large{10x- 15 + 15+ 4x= - 16- 13 + 15} \\ \displaystyle \large{10x + 4x= - 16- 13 + 15}[/tex]
Combine like terms.
[tex] \displaystyle \large{14x= - 14}[/tex]
Divide both sides by 14.
[tex] \displaystyle \large{ \frac{14x}{14} = \frac{ - 14}{14} } \\ \displaystyle \large{x= -1}[/tex]
