Answer:

6/25 or 0.24 (same thing)

Step-by-step explanation:

1. Get the reciprocal of the second fraction (-5/6) (reciprocal: flip the numerator and the denomenator)

2. You know have -1/5÷-6/5

3. Make the divison sign into a multiplication sign. (-1/5 x -6/5)

4. Multiply like you would any two fractions.

5. The answer: 6/25 or 0.24

When you are multiplying the numerators (-1 x -6), remember that two negatives make a positive when multiplying so the numerator in the final answer will be positive (6).

Hope this helps!

If 141 people attend a concert and tickets for adults cost $3.5 while tickets for children cost $2.5 and total receipts for the
Arturiano [62]

Answer: There are 69 adults and 72 children went to the concert.

Step-by-step explanation:

Let x be the number of adults, and y be the number of children.

x + y = 141

3.5x + 2.5y = 421.5

x + y =141

x = 141 - y

3.5(141 - y) + 2.5y = 421.5

493.5 - 3.5y + 2.5y = 421.5

493.5 - y = 421.5

-y = -72

y = 72

x + y = 141

x + 72 = 141

x = 69

Jeremiah is working on a model bridge. He needs to create triangular components, and he plans to use toothpicks. He finds three
icang [17]

Answer: No

Step-by-step explanation:

According to triangle inequality theorem which state that: the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Now let's test the given parameters if they obey this theorem

4 inches, 5 inches and 1 inch

4 + 5 = 9

9 > 1 correct

5 + 1 = 6

6 > 4 correct

4 + 1 = 5

5 not > 5 wrong

Therefore he won't be able to create the triangular component with these toothpicks without modifying any of the lengths

Solving special systems<br> {y=1/2x+4<br> {-1/2x+y=-5
ryzh [129]

Answer:

no solution

Step-by-step explanation:

Given the 2 equations

y = \frac{1}{2} x + 4 → (1)

- \frac{1}{2} x + y = - 5 → (2)

Substitute y = \frac{1}{2} x + 4 into (2)

- \frac{1}{2} x + \frac{1}{2} x + 4 = - 5 , that is

4 = - 5 ← not possible

This indicates the system has no solution

Which expression is equivalent to the given expression? (3m-4)^3(3m^5)
BabaBlast [244]

Answer: D.

Step-by-step explanation:

You want to cube each term in the parentheses. When you take an exponent to an exponent, you just multiply them. You get (27m^-12). In order to get rid of that negative exponent, you should put a one over the m term and make -12, +12:

(\frac{27}{m^12} )(3m^5)

Multiply the numerators to get:

81m^5

You now have:

\frac{81m^5}{m^12}

When you divide exponents, you subtract them. 5 - 12 = -7

You have m^-7 which is the same as 1/m^7. Finally, mulitply that by the 81 we left out to get the answer of D.
