Answer:

x = 6

Step-by-step explanation:

We can see that the the 32 degree angle plus the equation (9x + 4) is equal to 90 degrees.

We know this because the bottom line is a 180 degree angle, and we can see on the other side that it is a right angle.

If we were to turn that into an equation it would like like this:

(9x + 4) + 32 = 90

Now you just have to solve for x.

9x + 4 + 32 = 90

Combine like terms:

9x + 36 = 90

Subtract 36 from both sides

9x = 54

divide both sides by 9

x = 6

and you are left with the answer.

A shark weighs 405 kg and 68 grams a second shark weighs 324 kg and 75 g how much more does the first shark weigh in grams than

mariarad [96]

For this case we have to by definition:

1 kg equals 1000 grams

Shark 1:

405 kg and 68 grams

$405 kg * \frac {1000 g} {1kg} = 405,000 grams$

Thus, shark 1 weighs 405,068 grams.

Shark 2:

324 kg and 75 grams

$324 kg * \frac {1000 g} {1 kg} = 324,000 grams$

Thus, shark 2 weighs 324,075 grams.

Subtracting we have:

$405.068 grams-324.075 grams = 80.993 grams$

Thus, shark 1 weighs 80,993 grams more than the second.

Answer:

Shark 1 weighs 80,993 grams more than the second.

One solution to a quadratic equation is x= -5/3 What is true about any remaining solutions?

miv72 [106K]

Answer:

There is exactly one more real solution or there is exactly one more complex solution

Step-by-step explanation:

A quadratic equation is a polynomial of degree two

What this means is that a polynomial has two answers.

Now, from the question, we have an answer already which is a real root

Then the other answer which we do not have can take the form of two answers

It can either be a complex root or other wise be a real root

So the answer to this question is that ;

There is exactly one more real solution or there is exactly one more complex solution

Answer:

Gianna makes $18 per hour.

Step-by-step explanation:

Given Gianna makes 90$ for 5 hours. That means she should make $\frac{90}{5}$ $ = 18$ every hour.

Therefore we have:

HOURS DOLLARS

1 18

2 36

3 54

4 72

5 90

6 108

7 126

For the tabular column mark Hours on the x - axis and Dollars on the Y - axis. It can be plotted from the above table easily.

If Gianna works for 8 hours she would have made 8 X 18 = 144$.

So, she will earn 144$ in 8 hours.

To make 60$ she would have to work $\frac{60}{18}$ hours = 3.33 hours.
