Solve this equation -8-x=x-4x
Answers
Answer:
x=4
Step-by-step explanation:
-8-x=x-4x
Combine like terms
-8 -x =-3x
Add x to each side
-8 -x+x = -3x+x
-8 = -2x
Divide each side by -2
-8/-2 = -2x/-2
4 = x

Answer:
She is 1.5 meters below the sea level
Explanation:
The sea level is indicated by the number 0
What's above the sea level is indicated by +ve numbers
What's below the sea level is indicated by -ve numbers
We know that:
originally, her depth was 1 meter below the sea level
This means that her original depth is -1
Now, she dives an extra 0.5 meters, to get her final depth, we would add -0.5 to the original -1 meters
This means that:
her depth = -1 + (-0.5) = -1.5 meters
where the negative sign indicates that she is below the sea level
Hope this helps :)

The total number of cards including each pack after giving 3 cards from each pack will be 56.
What is the arithmetic operator?
Arithmeticoperators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Division = divide any two numbers or variables called division.
Multiplication = to multiply any two or more numbers or variables called multiplication.
As per the given,
Total number of packs = 8
Number of cards in each pack is 10 so total cards = 8 x 10 = 80 cards.
He gave 3 cards in each so 8 x 3 = 24 cards.
Remainingcards = 80 - 24 = 56 cards
Hence "The total number of cards including each pack after giving 3 cards from each pack will be 56".

Answer:
Jerome has 50 baseball cards left.
Step-by-step explanation:
Jerome had 8*10 = 80 baseball cards total. He then gave his sister three from each of the ten packs (3*10 = 30).
Therefore, Jerome has 80 - 30 = 50 baseball cards.

4) -r-10r
Answers
1) 12r - 8 - 12
Here the like terms are -8 and 12.
-8 - 12 = -20
12r - 20
2) n - 10 + 9n - 3
Here the like terms are n and 9n and -10 and -3.
To make it easier you can reorder the expression to be n + 9n - 10 - 3.
n + 9n = (1 + 9)n = 10n
-10 - 3 = -13
10n - 13
3) -4x - 10x
Here the like terms are the only two terms in the expression, -4x and -10x.
(-4 - 10)x = -14x
-14x
4) -r - 10r
Here the like terms are the only two terms in the expression, -r and -10r.
(-1 - 10)r = -11
-11r

Ratio is the relationship between the number of same unit to verify the how bigger or smaller is a number to the another when we compare two quantities to each we write them in the form of the ration. The ratio of local calls to long distance calls made by Jillian in that month is 9/5. Thus the option C is the correct option.
Given-
Total local phone calls made by the Jillian is 36.
Total long distance phone calls made by the Jillian is 20.
To get the value of ratio we need to know about the term "ratio".
What is the ratio?
Ratio is the relationship between the number of same unit to verify the how bigger or smaller is a number to the another when we compare two quantities to each we write them in the form of the ratio.
Now to find out the ratio of local calls to long distance calls made by Jillian in that month we need to divide the number of local calls to the number of long distance calls.
Suppose r be the ratio of local calls to long distance calls made by Jillian in that month. Hence.
Hence the ratio of local calls to long distance calls made by Jillian in that month is 9/5. Thus the option C is the correct option.
