Consider the equation x 5 − 2 = 11. Each of these values might be the solution to this equation. Verify the correct solution by substituting each value into the equation. Which is the correct solution?

Answers

Answer 1

Answer:

x = 65

Step-by-step explanation:

Complete question is:

Which is the correct solution?

x = 1.8

x = 2.6

x = 45

x = 65

SOLUTION:

The given equation is : [tex]\frac{x}{5}-2=11[/tex]

Substituting all the values of 'x' one by one

 

-> For  x = 1.8  : [tex]\frac{1.8}{5}-2=11[/tex]

-1.64≠11

-> For x = 2.6 : [tex]\frac{2.6}{5}-2=11[/tex]

-1.48≠11

-> For x = 45 : [tex]\frac{45}{5}-2=11[/tex]

7≠11

-> For x = 65 : [tex]\frac{65}{5}-2=11[/tex]

11=11

Therefore, by substituting x in every equation, x = 65

Answer 2

Answer:

Substitute 7 for a.

Simplify the equation after substituting the value for a.

Verify that a = 7 is correct when the result is a true statement.

Step-by-step explanation:

Here, the given equation is,,

And, after solving it the result is,

a = 7

We can check whether a result is the solution of an equation by substituting the result in the given equation.

If we get a true statement, then the result is the solution of the equation.

Thus, for verifying the solution, steps are as follow,

Step 1 : Substitute 7 ,

-9(7-5) = -18

Step 2 : Simplify the equation after substituting the value of a  

-9(2) = -18    

Step 3 : Verify that a = 7 is correct when the result is a true statement.

-18 = -18

Find a monic quartic polynomial f(x) with rational coefficents whose roots include
x=1-sqrt2, and x=2+sqrt5. Give your answer in expanded form.

Answers

Answer:

The polynomial hose roots are :

x = 1 - √2 and

x = 2 + √5

Is

x² - (3 + √5 + √2)x + 2 + √5 - 2√2 -√10 = 0

Step-by-step explanation:

The roots of the equation are

x = 1 - √2 and

x = 2 + √5

(x - 1 + √2)(x - 2 - √5) = 0

x²- 2x - x√5 - x + 2 + √5 + x√2 - 2√2 - √10 = 0

x² - (3 + √5 + √2)x + 2 + √5 - 2√2 -√10 = 0

This is the expanded form

This spinner will be spun twice.What is the probability of spinning an odd number both times?

Answers

The Probability of spinning an odd number both times is [tex]\dfrac{1}{2}[/tex].

The formula of Probability

Probability is calculated by the ratio of favourable outcomes and the total number of outcomes.

How to find the probability?

The total number of outcomes of spinning numbers will be 4 that is 1,2,3,4.

And in which the odd numbers are 1,3.

Therefore the favourable outcome of spinning an odd number both the times will be 2.

Then, the probability will be

[tex]P=\dfrac{2}{4} \\P=\dfrac{1}{2}[/tex]

So, the probability of spinning an odd number both times will be [tex]\dfrac{1}{2}[/tex].

Mama Mia restaurant used \dfrac12 2 1 ​ start fraction, 1, divided by, 2, end fraction of their mozzarella cheese making pizza and the remaining 646464 ounces making pasta. How many pounds of mozzarella cheese did Mama Mia start with?

Answers

Answer:

8 pounds

Step-by-step explanation:

CORRECT: the remaining 64 ounces making pasta.

Assuming 'x' be the total ounces of mozzarella

we know that

making pizza :  (1/2)*x => x/2

therefore, making pasta: [x-x/2] => (2x-x)/2 =>  x/2

making pizza=making pasta=x/2

Thus, (x/2)=64

x=(64)(2)

x=128 ounces

Note that 1 ounces=0.0625 pounds

then,  128 ounces*0.0625=8 pounds

Thus, Mama Mia started with 8 pounds of mozzarella cheese

Now, pick two points. Let's pick (-1,-9) and (0,-7). We can add these into the slope formula.

[tex]Slope(m)=\frac{y2-y1}{x2-x1}[/tex]

[tex]m=\frac{-7-(-9)}{0-(-1)}[/tex]

B)tony
C)Robert
D)John

Answers

Answer:

C

Step-by-step explanation:

Let's compare 3/7 and 3/4 first. These two fractions have the same numerator but not the same denominator, so the fraction with the smaller denominator will be larger. Therefore, 3/4 is larger, so we can eliminate A.

4/9 is less than 1/2, and 3/4 is greater than 1/2, so 3/4 is greater than 4/9 and we can eliminate B. The same goes for D.

Therefore, our answer is C) Robert. Hope this helps!

How do I find the perimeter for a square and a triangle?












Answers

Answer: 24 inches.

Step-by-step explanation:

You can find the perimeter of the polygon by adding the side lengths.

First, find the missing side lengths.

There is a short space between the right side of the square above the triangle. The triangle is 3 inches tall, and the square is 4 inches tall, so that space is 1 inch long.

We can then add the sides to find the perimeter:

4 + 9 + 5 + 1 + 5 = 24 inches long.

Keep in mind that the three inches of the triangle is not included in the sum because it is not on the outside of the polygon. The perimeter only includes the lengths of the exterior sides.

In the basketball game, the Buffalo made a total of 25 shots. Some of the shots are 2- point shots while others are 3- point shots. If the Buffalo scored a total of 57 points, how many were 2-point shots?

Answers

Let's let x be the number of 3-point shots made.

Let's let y be the number of 2-point shots made.

So, then we have:

x+y = 25

And we have

3*x + 2*y = 57

So, we can solve this by substitution. Solving the first equation for x:

x=25-y

Now, plugging into the second equation:

3*(25-y) + 2*y = 57

Simplifying:

75-3y+2y = 26

75-57 = y

y=18

So the player made 18 2-point should and  7 3-point shots for a total of 57 points!

Answers

Answer:

The area is  

[tex]72yd^{2}[/tex]

(square yards)

Step-by-step explanation:

Explanation:

In the given triangle a base  24 y d  and the corresponding height  6 y d

is given, so to calculate the area we can use:

A = 1 2× b × h

If we substitute thegiven numbers we get:

A = 1 2 × 24 × 6 = 12 × 6= 72

The units of base and height are the same (yards), so the calculated area is in  y d 2  (square yards)

Answer: The area of the given triangle is  72 square yards.
