1) Answer: 113

3^3 + 2[64 - (3x7)]

27 + 2[64 - (3x7)]

27 + 2[64 - 21]

27 + 2[43]

27 + 86

= 113

3) Answer: (-1, 11)

Since the problem said that it was 11 points across the y-axis, you just have to replace the -12 with 11 because -12 is the y-value.

4) 5.5 quarts = 11 pints

1 quart is equal to 2 pints, so just double the amount of quarts.

5) 120 minutes (or 2 hours)

Set up a proportion and solve for the missing value. (24/x = 6/30)

6) 5 and 8

5 x 8 = 40

5 + 8 = 13

8) -8.95

1.3 + (-6) + (-4.25)

1.3 - 6 - 4.25

-4.7 - 4.25

= -8.95

Ashley drove 5 hours and 45mins and drove 391 miles. How far did she drive in 1 hour

klasskru [66]

1 hour = 60 minutes
5 x 60 = 300
300 + 45 = 345

391 miles/345 min = 1.13 miles per min
1.13 x (60 min/1 mile) = 67.8 miles per hour

Ashley drove ~67.8 miles per hour

hope this helps

If Logx (1 / 8) = - 3 / 2, then x is equal to

snow_tiger [21]

Answer:

Let's solve!

Step-by-step explanation:

$logx^{\frac{1}{8} } = -\frac{3}{2}$

$then$

$10^{-\frac{3}{2}} = x^{\frac{1}{8} }$

$(10^{-\frac{3}{2} })^{8} = (x^{\frac{1}{8} })^{8}$

$x = 10^{3*4} = 10^{-12}$

$x= 10^{-12}$

If the equation looks like this, then it has the solution

$x= 10^{-12}$

Another answer is

√x = 2 or x = 4

I hope this helps!

12. The Opera is collecting monies in advance for ticket sales. The tickets cost $17.50 each.

Debora [2.8K]

Answer:

The number of tickets they have sold in advance are summed up with the following equation and solution:

Equation: $\frac{6842.50}{17.50}$ [the final answer should be in dollars]

Solution: The Opera sold 391 tickets in advance.

Step-by-step explanation:

First: Review some background information:

Let's see what the problem gives us to answer it. I'll bold out the important parts:

The Opera is collecting monies in advance for ticket sales. The tickets cost $17.50 each. If they have collected $6842.50 already, then how many tickets have they sold in advance?

We know how much the tickets cost and how much money they have earned from selling tickets, we can find out how much tickets they have sold.

Second: Solve the problem:

We can solve this problem using many ways, but I'm just going to pick one. We will use proportions to answer this. Now thoughts might be going through your head like this: What is this guy saying? What in the world is proportions? Well hopefully you learn from this example (Please don't take offense if you do know how to do proportions).

First we set up two fractions. One ticket costs $17.50, so we will use it to set up our first fraction: $\frac{1}{17.50}$ . We don't know how many tickets all together cost $6842.50 so we will use the variable: x. Now, we can set up our second fraction. x tickets costs $6842.50 so our second fraction will be: $\frac{x}{6842.50}$ . Now we must use cross multiplication. We multiply the numerator of the first fraction times the denominator of the second fraction, and then we multiply the denominator o the first fraction times the numerator of the second fraction. That's what we would do usually. But now, since we have a variable, we must use cross multiplication to solve for this variable. So we multiply the the numerator of the first fraction times the denominator of the other fraction and then we divide that answer times the denominator of the first fraction (You don't have to set it up like this).So let's solve this question:

$\frac{1}{17.50}$ $\frac{x}{6842.50}$

1 x 17.50 = 17.50

6842.50 ÷ 17.50 = 391

So our equation is 6842.50 ÷ 17.50, and our solution is 391 tickets
