ambiente apent 5/8 of har money and sabedoria The rest.if she sprnt 45$,how much money did she have at first?​

Answers

Further explanation
Given:
Abbie spent ⁵/₈ of her money and saved the rest.
She spent $45.
Question:
How much money did she have at first?
The Process:
The meaning of "Abbie spent ⁵/₈ of her money" is that she has spent 5 of the 8 parts of the money she had at first.
Let us make a pattern of 8 units for the amount of money that Abbie had at first.

Since Abbie spent ⁵/₈ of her money, then we create a pattern of 5 units containing $9 each. Recall that

From the pattern above, we can see that
Let us calculate how much money Abbie had at first.



Thus, the money Abbie had at first is $72.
The complete pattern of Abbie's initial money is as follows:

- - - - - - - - - -
Quick Steps:
Let M as Abbie's initial money.

Both sides are multiplied by ⁸/₅ so that M is the subject alone on the left side.

We crossed out 5 and 45.


Thus, the money Abbie had at first is $72.

  3)  (0, 0)

  4)  (-1, 2)

Step-by-step explanation:

I find a graphing calculator provides a quick solution to a system of linear equations.

3) The solution is (x, y) = (0, 0)

4) The solution is (x, y) = (-1, 2)

__

In each case, the y-term can be eliminated by multiplying the first equation by 3. For problem 3) the resulting equations must be added. For problem 4), the resulting equations must be subtracted.

Solve the equation x = 5/3 (pie) (r^3) for r.

Answers

Answer and Step-by-step explanation:

To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.

[tex]x = \frac{5}{3} \pi r^{3}[/tex]

Multiply each side by [tex]\frac{3}{5}[/tex], then divide by [tex]\pi[/tex] (pi)

[tex]\frac{3x}{5\pi } = r^{3}[/tex]

Now, take the cubed root of both sides.

[tex]\sqrt[3]{\frac{3x}{5\pi } } = r[/tex]

^^ That is the answer.

THE amusement park won't allow kids to ride roller-coasters until they are a minimum of 48 inches tall. Michael is now 42 inches tall, and grows about 1/2 inch every month. How many months will it be until Michael can read a roller coaster? Please show me the individual steps?

Answers

Answer: It will one year (or 12 months) before Michael is able to ride the roller coaster.

Step-by-step explanation: Because he grows a half inch every month, this means that It takes him two months to grow one full inch. Because he has to grow six inches, you just multiply 2 by 6 to get 12 months or one year.

Answer:

48-42=6, which is how much Michael needs to grow.

1/2x=6, where x is the number of months

x = 12 months.

1 year = 12 months so the answer is one year.

Gabrielle is 13 years older than Mikhail. the sum of their ages is 113. what is mikhails age?​

Answers

Step-by-step explanation:

g=m+13

g+m=113

use substitution

Answer:

50 years old

Step-by-step explanation:

Let's say that Mikhail's age is x.

If so, Gabrielle's age would be 13 years older, therefore x + 13

We know that the sum of their ages is 113, so we can form this equation:

x + x + 13 = 113

Solving this equation, we get:

x + x = 100

2x = 100

x = 50

50 is Mikhail's age, so Gabrielle's age is 63

Evaluate when
a =3 b= 4.5 and h = 6

Answers

Answer:

For Example:  Evaluate a2b for a = –2, b = 3, c = –4, and d = 4.

Step-by-step explanation:

To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the "minus" signs. Especially when I'm just starting out, drawing the parentheses first may be helpful:

a2 b

(    )2 (  )

(–2)2 (3)

(4)(3)

12

Note how using parentheses helped me keep track of the "minus" sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with –4, which would have been wrong.

By the way, it turned out that we didn't need the values for the variables c and d. When you're given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won't be included in any particular exercise in the set.

Evaluate a – cd for a = –2, b = 3, c = –4, and d = 4.

In this exercise, they've given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:

(–2) – (–4)(4)

–2 – (–16)

–2 + 16

16 – 2

Answer:

One of the angles in the triangle might be 50.

AND

The length of the third side must be 11cm or smaller.

Step-by-step explanation:

-The triangle might be an equilateral triangle (having all the same sides and angles). False, since the triangle sum theorem states that all angles inside of a triangle must add up to 180, so an equilateral triangle would need to have all three angles at 60 degrees.

-One of the angles in the triangle must be 120 (false; it can be anything above 90, which is not only 120)

-The length of the third side must be 11cm or smaller. (True, Triangle Inequality Theorem)

-One of the angles in the triangle might be 50 (possibly, so very much true)

i really need help i don't get it

Answers

Answer:

The correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.

Step-by-step explanation:

By Hierarchy Rules of Operators, we must follow these steps:

(i) Subtract 6 from 14.

[tex]\frac{1}{2}\times 8\times 6 + 4[/tex]

(ii) Multiply the result in (i) by [tex]\frac{1}{2}[/tex] and 6.

[tex]24+4[/tex]

(ii) Add 4 to the result in (ii).

[tex]28[/tex]

Hence, the correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.
