Wally buys a baseball card for $5, sells if for $6, buys the same card back for $7 the following days,
and then resells it for $8. How much profit or loss occurred in all these transactions combined?
Answers
Answer:
3 dollars profit
Step-by-step explanation:
if he has $5 b-card and sells it for $6 he gains a dollar. But if he buys it back for $7 then he lost $2 from his original price. In the end, he sells it for $8 so he gains a $3 profit. 8 - 5 = 3

This is a good question to estimate the answer. That will get rid of the ones you don't have to check - maybe.
123 miles in 3 hours = 123/3 = 40 about Too far away. Not answer
96 miles in 3 hours = 100 / 3 = 33 about. This is one you should check.
288 miles in 9 hours = 270/9 = 30 about. Another one to check
66 miles in 3 hours = 66/2 = 33 Not right.
310 miles in 10 hours = 310/10 = 31 Not right
Some of these do not need to be rounded to get the answer. If the division is the same as the question and it does not come to 32 then it will not be included in the answer.
B gives 32 miles / hour. B is one of the answers
C gives 32 miles / hour. C is one of the answers.

Answers
Answer:13
Step-by-step explanation:
-4/12 = -0.33
-2/15 = -0.133
This gives you (-0.33)(-0.133)
Next, multiply both brackets together.
(-0.33)(-0.133) = appx. 0.044
Now that you have the product of the two brackets, calculate 5/6
5/6 = 0.833
Finally, sum it all up. Since the last two numbers are negative, we subtract them.
0.833 - 0.33 - 0.133 =
Therefore, the answer is 0.37

Step-by-step explanation:
Given that:
Timothy has a set of plastic squares. the tables shows the relationship between A,the area of each square in square centimeters, and s, the side length of each square in centimeters.
To Find:
Which equation can be used to represent the relationship between A and s for these squares?
Solution:
From the given table:
A = 1 S = 1 A ÷ S = 1 ÷ 1 = 1 = S
A = 4 S = 2 A ÷ S = 4÷ 2 = S
A = 49 S = 7 A÷S = 49 ÷7 = 7 = S
A = 64 S = 8 A÷S = 64÷8 = 8 = S
From the solving above we can see that the equation that can be used to represent the relationship between A and s for these square is A = S · S

Natasha had d dollars. She bought 2 ice creams which cost x dollars each. How much money does she have left?
Answers
Answer:
d-2x
Step-by-step explanation:
d is the amount of dollars she had, 2x is the amount of money she used to buy ice creams.
We can write an equation to resemble the problem.
We can write "2x" since she bought 2 ice creams and the price of each is unknown.
We can subtract that by "d" to find how much money she has left.
Put everything together.
2x - d

We can then use our new found information for w+w+x+x = 24. We know that W = 5, so: 5+5+x+x = 24, and then 10+2x (because there were two Xs (if it was x+x+x, it would be 3x)) so, 10+2x=24, we can subtract 10 from both sides to get 2x by itself:
2x=24-10,
2x=14,
Then to get X by itself, we can divide by 2 on both sides:
2x/2 = 14/2
x=7
So now we know X’s value, X=7

Step-by-step explanation:
A ) 6x + 5 - 2x = 4 +4x +1

B) -(2x + 3) = -2x - 6
⇒ -2x - 6 = -2x - 6
C) 4(2x - 1) = 6x - 4 +2x
⇒ 8x - 4 = 8x - 4
D) 6x -(3x + 8 ) = 16
⇒ 3x = 24
⇒ x = 8
Hence, A, B, and C all have infinite solutions but D has an exact solution.

Answer:
B) Square root of 45 and C) Square root of 30, are both irrational numbers, because they aren't perfect squares.
Explanation:
A square root can be defined as, "a factor of a number that, when multiplied by itself, gives the original number."
For example: 8 squared (8^2) is the same as 8 × 8 , which equals 64 , so the square root of 64 is 8. Since 64 is a perfect square, then it makes it a rational number.

Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Choose all that give the correct effect on the linear graph of the parent function ƒ(x).
f(x) is replaced with f(x) + 5 shifts the line 5 units up
f(x) is replaced with f(x − 8) shifts the line 8 units left
f(x) is replaced with 4f(x) stretch vertically by a factor of 4
f(x) is replaced with f(3x) compress horizontally by a factor of 1/3
Answers
Answer: since the parent function is f(x), then i think....
f(x) + 5 is the shifted 5 units up of f(x)
then the first answer is correct
f(x - 8) is 8 shifted 8 units right of f(x)
then the second answer is wrong,
f(x) is replaced by 4f(x) means it stretched vertically by a factor of 4
the the third answer is correct
f(x) is replaced with f(3x) compressed horizontally by a scale factor of 1/3
then the fourth answer is correct
