Answers

Answer 1

Answer: The answer would be -13. There's a negative sign outside the brackets, which means that it's -13 even if simplified.

Answer 2

Answer: It should be positive 13 because the 2 negatives cancel each other out

Why does 0.50 m equal to 50 cm???

Answers

because to convert from m to cm you have to times it by 100, so 0.50 m times 100 is 50 cm

-37= n/23
what is n?

Answers

-37 = n
23

to solve for n, undo what is happening to the n. if the n is being divided by 23 to get -37, then multiply both sides by 23 to figure out what n is.

-37 * 23 = n * 23
23

-851 = n

the 23 is crowding the n by division
so to undo that we multiply both sides by 23
to get n alone

n = -37 * 23 = - 851

so n = - 851

Answers

Answer: B

Heyy, this is a quadratic equation and I used the null factor law to solve this. So basically, find 2 numbers that multiply together to get 56, e.g. 8x7. But you have to make sure that the 2 numbers you choose add up to 15. Then put it in null factor law form, e.g. (z-8)(z-7)=0. Then just solve for 0. E.g. z-8=0. Which is 8. If you want, you can expand to check if it matches the original equation.. :')

The function C (1)31+ 2 is the cost to order a lip gloss L,including the flat rate shipping charge. Which of the for
represents the cost of purchasing 5 lip glosses? (1 point)

C (5)=5
1=5
C (5)
C (1) = 5

Answers

Answer:

Therefore, the cost of purchasing 5 lip glosses, as represented by the function C(5), is 41.

Step-by-step explanation:

To find the cost of purchasing 5 lip glosses, we need to use the given function C(1) = 31 + 2, which represents the cost of ordering one lip gloss including the flat rate shipping charge. To find the cost of purchasing 5 lip glosses, we can substitute 5 for the variable in the function: C(5) = 31 + 2 * 5 C(5) = 31 + 10 C(5) = 41

Final answer:

The cost of purchasing 5 lip glosses represented in the function C(1)=31+2 is evaluated as C(5)=31+2*5, which equals 41 units.

Explanation:

This question involves the mathematical concept of functions, specifically, simple linear functions. In this example, we have the function C(1)=31+2, which informs us that the cost to order one lip gloss, denoted as 'L', is '31 plus twice the number of lip glosses ordered'

To answer the question 'What represents the cost of purchasing 5 lip glosses?', we substitute the number of lip glosses we want to buy (5) into our function. So instead of evaluating C(1), we evaluate C(5)=31+2*5, following the same structure of '31 plus twice the number of lip glosses ordered'. The solution to this would be C(5)=41, meaning it would cost 41 units (the currency isn't stated) for 5 lip glosses.

Sandra wants 1/6 of the fruit in her fruit baskets to be bananas. If the greatest number of fruit that will fit in each basket is 24 what fraction can represent the possible ways Sandra can have the bananas in the fruit baskets? Explain your answer.

Answers

If the total capacity of the basket is 24 to find 1/6 you divide 24 by 6 and get 4. 4 is equal to 1/6 of 24 which means Sandra can only bring 4 bananas.

Solve 4/(x + 1) - 1/x = 1 over the real numbers.

Answers

$( 4)/(x + 1) - (1)/(x) = 1 \n \nx+1\neq 0 \ \ \ and \ \ \ x\neq 0 \n \nx\neq -1 \ \ \ and \ \ \ x\neq 0 \n \nD=R\setminus \left \{ -1,0 \right \}$

$( 4x- (x+1))/(x(x + 1)) = 1 \n \n( 4x- x-1 )/(x^2+ x)=1 \n \n( 3x -1 )/(x^2 + x) = 1 \n \n3x-1=x^2+x\n \n x^2+x-3x+1=0$

$x^2-2x+1=0 \n \n (x-1)^2=0 \n \nx-1=0 \n \nx=1$

Ok sorry I guessed this one but it was x = 1
4/(1+1) - 1/1 = 1
2 - 1 = 1
And it's right :)
