Answer 1

Answer: x-4y=5
x=3y-2
x-4y=5
x-3y=-2
-y=7
y=-7
x+21=-2
x=-23
HOPE I HELPED!!!

Answer 2

Answer: well if x = 3y - 2, then everywhere u see and x remember it equals 3y - 2
so (3y - 2) - 4y = 5 then u distribute
-3y + 2 - 4y = 5 then combine the y's
-7y + 2= 5 then subtract 2 from each side
-7y = 3 then divide -7 on both sides
y = 3/-7
x = -3.28

What number are listed in the stem and leaf plot above

Adele also must choose between leather or cloth seats for her vehicle. Leather seats come in three color choices; brown, black, and blue. Cloth seats come in two color choices; tan and gray. Using multiplication, Adele says she has (2)(3)(2), or a total of 12, choices for seat covers. Is she correct? Explain why or why not.

Answers

No, she is not correct because she has 5 options of seat covers to choose from.

We have to determine the number of options for seat covers

Here given that,

Color options for leather seats =3

Color options for cloth seats = 2

What is probability?

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

What is the formula for combinations?

The total number of combinations = nCr!/n!(n-r)!

Where n is the total number of choices available, and r stands for the number of choices to be made.

Here the number of leather seat options presented = 3

The number of options available for cloth seats =2

Total number of options = leather + cloth = 3 + 2 = 5

The number of options available to her

⇒ 5!/ 1!×(5-1)!

⇒ 5!/4!

⇒ 5×4!/4!

⇒ 5

She can only select one style of cover at a time, therefore she has five options for seat covers. The cover may be made of tan cloth, grey cloth, blue leather, black leather, or brown leather.

Hence, she has 5 options of seat covers to choose from.

Answer:

Sample response: Adele is not correct. There are only 5 choices. Here, we are not able to use the fundamental counting principle because there are different choices for each material.

19) At a local river, there were 48 alligators lying on the riverbank. If of the alligators wereasleep, how many were not asleep?20) At a charity bike rally, offhe student population of oakleaf Junior High Schodparticipated. If there are 1students at ouJH, how many participated in the bike rally?

21) out of 18 times at bat, Kayla got a hitof the time and Tia got a hitof the time. Whogot more hits? How many more?

Answers

19) 48 alligators; 7/8 of the alligators were asleep. How many were not asleep?

8/8 - 7/8 = 1/8
48 * 1/8 = 48/8 = 6 alligators were not asleep.

20) 2/3 of the student population participated. 1,500 is the student population of the school. HOw many attended the bike rally?

1500 * 2/3 = 1500*2 / 3= 3000 / 3 = 1000 students attended.

21) 18 times at bat:
Kayla 5/6 of the time = 18 * 5/6 = 18*5 / 6 = 90/6 = 15 hits
Tia 8/9 of the time = 18 * 8/9 = 18*8 / 9 = 144/9 = 16 hits

Tia got more hits.

Richard walks every day for exercise at a rate of 1 kilometer every 12 min. At this rate ,how many meters can Richard walk in a hour? please helppppppp

Answers

Answer: He can walk 5000 meters in one hour.

Step-by-step explanation:

According to the question,

$\text{ The distance he covered in 12 minutes }=\text{ 1 km}$

$\text{ The distance he covered in 60 minutes }=\text{ 5 km}$

$\text{ The distance he covered in 1 hour }=\text{ 5 km}$

Now, 1 km = 1000 meters,

$\implies \text{ The distance he covered in 1 hour }=\text{ 5000 m}$

60 minutes in an hour
60÷12=5
1,000 meter in 1 km
5×1=5
5×1000=5000
therefore, 5000 meters

What is the approximate area of the figure

Answers

Answer:

option b

137.1 cm²

Step-by-step explanation:

The given figure consist of two shapes

1) half circle

2) rectangle

Formula to use to calculate the area of this figure

half circle + rectangle

1/2πr² + h(b)

where r = radius = diameter/2 = 8/2 = 4 cm

h = height = 14 cm

b = base = 8 cm

plug in values in the formula

1/2(3.14)(4)² + (8)(14)

25. 133 + 112

137.13 cm²

Since all 4 sides of the pyramid are the same we just need to find out the area of one face then multiply it by 4. The formula to figure out the area of a triangle is base x height ÷ 2. Now we just need to plug in the numbers.
Surface Area=bxh÷2
SA=7.2x6.2÷2
SA=44.64÷2
SA=22.32

Now that we have the area of one face we need to multiply it by 4.
22.32 x 4 = 89.32

The closest answer to 89.32 would be 88.3cm2 so the answer is B.

The answer would be B.
