The fact that it can turn its head 180 degrees is just extra information. They tell us that it is 10.5 cm long. What they're asking for is the length in a mixed number, so 10.5 as a mixed number.

Answer:

The required mixed number is 10\frac{1}{2}.

Step-by-step explanation:

Consider the provided information.

It is given that praying mantis at the right is 10.5 centimeters long.

We need to find the mixed number represents this length.

Mixed number: Mixed numbers are the numbers which consists an integer and a proper fraction part.

Now consider the provided length 10.5

10.5 can be written as: 10 + 0.5

Here 10 is an integer, now we just need to change 0.5 into fractional form so that we can have a mixed number.

0.5 can be written as:

0.5=\frac{5}{10}=\frac{1}{2}

Thus, the number is 10+0.5=10+\frac{1}{2}=10\frac{1}{2}

Hence, the required mixed number is 10\frac{1}{2}.

Because of the direction of the line, the slope needs to be negative. This eliminates B.

The slope of the line is -7/6, so D is the correct answer.

What is the x-value of the solution of the system of
Nady [450]

Answer:

x = -1, y = -4

Step-by-step explanation:

Let's solve our system of equations by substitution.

y = 5x + 9y = −x + 3

Step: Solve = 5x + 9 for y:

y = 5x + 9

Step: Substitute 5x + 9 for y in y = −x + 3:

y = −x + 3

5x + 9 = −x + 3

5x + 9 + x = −x + 3 + x (Add x to both sides)

6x + 9 = 3

6x + 9 + −9 = 3 + −9 (Add -9 to both sides)

6x = −6

6x/ 6 = −6/6(Divide both sides by 6)

x = −1

Step: Substitute −1 for x in y = 5x + 9:

y = 5x + 9

y = (5)(−1) + 9

y = 4(Simplify both sides of the equation)

So our answers are y = -4 and x = -1.
