Answers

Answer:

20

Step-by-step explanation:

8x=6x+5 (subtract 6x from both sides)

2x =5 (divide by 2 both sides)

x=2.5

8x= 8*2.5 = 20 (substitute 2.5 for x)

or 6x+5 = 6(2.5)+5 = 20 (substitute 2.5 for x)

The perimeter of this shape is 30 feet. What is the length of the missing side?

Answers

Answer:

The answer is 4ft.

Step-by-step explanation:

If you add:

7ft + 3ft + 5ft + 11ft = 26ft

Then if you take away the whole perimeter of the shape by the sides added so far:

30ft - 26ft

It would equal:

30ft - 26ft = 4ft

4ft is the answer.

The value of the length of the missing side is 4 ft and this can be determined by using the arithmetic operations.

Given :

The perimeter of this shape is 30 feet.

The following steps can be used in order to determine the length of the missing side:

Step 1 - The arithmetic operations can be used in order to determine the length of the missing side.

Step 2 - Let the length of the missing side be 'x'.

Step 3 - So, the perimeter of the given figure is given below:

[tex]30 = x+ 7 +3+5+11[/tex]

Step 4 - Simplify the above expression in order to determine the value of 'x'.

[tex]x=30-26\\x = 4[/tex]

So, the value of the length of the missing side is 4 ft.

The sum of two numbers is 15. Twice one number equals 3 times the other. Find the numbers

Answers

Answer:

6 and 9

Step-by-step explanation:

x + y =15

2x = 3y             Set up system of equations

x = [tex]\frac{3y}{2}[/tex]             Solve for x

[tex]\frac{3y}{2}[/tex] + y = 15     Substitute

3y + 2y = 30

y = 6

x = 9

Which of the following is true:
A) It is NOT a relation and is a function
B) It is NOT a relation and is NOT a function
C) It is a relation and is NOT a function
D) It is a relation and is a function

Answers

Answer: D

Step by Step: Even though the y value repeats, to be considered not a function is when the X value repeats

The given set of ordered pairs is not a function. The correct option is (C).

What is a function?

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

For the given set of ordered pairs, the first element of each pair belongs to the domain and the second element belongs to the range.

If there are two values of y for the same value of x, then it is not one to one mapping which implies that this ordered pair does not represent a function.

Hence, the given set of ordered pairs is a relation but not a function.

A hang-glider 25 meters above the ground started to descend (go down) at a constant rate of 2 meters per second. Which equation could be
used to determine the height h of the glider after t seconds of descent?

Answers

Answer:

Step-by-step explanation: h = -2t + 25

2t = the distance the glider will pass descending with constant speed of 2 m/s (distance = speed*time)

This might not seem 1unusual. My mother hates cats. Perhaps hate is 2 to strong a word. She definitely fears them. She cant help it. I guess 3 one could say this fear is inherited. Her mother, her three aunts, and her grandmother all share this phobia. Nonetheless, the kitten is a beloved member of our family now. 4 Heres the story:5 One summer morning in August, Mom and Aunt Fran went to the school track to walk. Off in the distance they heard a noise that sounded like a baby screaming. It was coming from a dumpster near the cafeteria. Alarmed, they moved closer to investigate. The wailing grew louder. Aunt Fran gasped when she saw the tiny head of a kitten trapped in a small opening in the bottom of the dumpster. 6 Its body could not make it through the hole. Hopelessly trapped, 7 we saw that the creature continued to shriek. The women looked around for a mother 8 cat. None in sight.They realized that the summer heat would be unbearable by midday. Quelling their fears, they rattled off options: call for someone to come help; push the kittens head back into the dumpster; 9pulling the rest of its body out of the opening; leave and hope someone who is not afraid finds the kitten in time; ignore the screeching and get walking.10 Mom picked up a discarded jacket and covered the kittens head. She pulled gently, then firmly, but that kittens body was not coming out. So now it was Aunt Frans turn. After several attempts she pushed the kittens head back into the dumpster. Maternal instincts kicked in and my mother climbed into the dumpster. 11 Cautiously, she picked up the kitten.Aunt Fran 13 said we oughtta name her D.D. for dumpster diver, but we were set on Lily. After our trip with the kitty to the vet, we learned that Lily is a boy! Of course we plan to change his name. We havent convinced Mom that we need a friend for the kitty, but I am optimistic. I like the name Frank, but my sister is pushing for Harold. Whatever name we choose, I am glad that mom and Aunt Fran were able to face their fears.What traditional theme is conveyed through this story?Question 19 options:The importance of family petsThe importance of sistersThe importance of overcoming fearsThe importance of family Adelberg Company has two products: A and B.
