Answer:

25

Step-by-step explanation:

\(105+3x=180 \\ \\ 3x=75 \\ \\ x=25\)

Answer:

The answer is 25 degrees

Step-by-step explanation:

If you subtract 180 - 105 then you get 75.
Then you divide it by 3.
One circle is 360 degrees thus half of it is 180.
If you know one angle is 105 degrees then subtract it from 180.
If the number is 3x then you have to divide it by 3 to get x alone.
Hope it helps! :)

1. In the first problem, we need to subtract 1 from 9 since there is an addition:

9 – 1 = 8

Next, divide 8 by 2, and we get:

8 ÷ 2 = 4

This means that x = 4

Finally, check the answer by:

2(4) + 1 = 9

2. In the second problem, we need to subtract 3 from 19 since there is an addition:

19 – 3 = 16

Next, divide 16 by 4, and we get:

16 ÷ 4 = 4

This means that x = 4

Finally, check the answer by:

4(4) + 3 = 19

3. In the third problem, we need to add 2 with 7 since there is subtraction:

2 + 7 = 9

Next, divide 9 by 3, and we get:

9 ÷ 3 = 3

This means that x = 3

Finally, check the answer by:

3(3) – 2 = 7

Hope this helps :)

Step-by-step explanation:

6 km

Answer:

1195

Step-by-step explanation: add the first 2 weeks and then subtract them from the total visitors

A. The number of visitors for the third week was 1,195.

B. A total of 972 students visited Sea Animal Park during the 3 weeks.

C. 30 groups to ensure that each student can pet the dolphins, not 29 as Kelly calculated.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

A. To find the number of visitors for the third week, we can subtract the number of visitors for the first two weeks from the total number of visitors for the first three weeks:

3,840 - 1,368 - 1,277 = 1,195

Therefore, the number of visitors for the third week was 1,195.

B. To find the total number of students that visited the Sea Animal Park during the 3 weeks,

we can multiply the number of buses by the number of students on each bus:

18 buses x 54 students per bus = 972 total students

Therefore, a total of 972 students visited Sea Animal Park during the 3 weeks.

C. Kelly did not correctly solve the division problem.

If there were 4 groups of 52 students each, then there would be a total of 208 students.

To find the total number of groups needed so that each student can pet the dolphins, we can divide the total number of students by the number of students in each group:

208 students / 7 students per group = 29.71 groups

This means that we would need 30 groups to ensure that each student can pet the dolphins, not 29 as Kelly calculated.

Answer:

Hey there!

2x-5y=10

Add 5y on both sides to get: 2x=10+5y

Divide by 2, not 2x. This will isolate the x.

x=5+2.5y

x=2.5y+5

Hope this helps :)

Answer:

x = 5 + 5y/2

Step-by-step explanation:

When you get to 2x = 10 + 5y,

you should divide both sides with 2 only instead of 2x. Because if you divide 2x on both sides, the left side would only remain 1  (since 2x/2x = 1)

2x = 10 + 5y

x = (10 + 5y) / 2

x = 10/2 + 5y/2

x = 5 + 5y/2 .( or  5 + (5/2)y)

Answer:

First combination: One $5 bill, one $1 bill, two quarters and one dime.

Second combination: One $5 bill, one $1 bill, two quarters and two nickles.

Step-by-step explanation:

I highly suggest reading it to make sure you understand it

Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60

So we have to work with $6.60

Now lets think of the obvious/easiest.

A $5 bill is going to be our best friend in this.

We have to do

6.60-5.00=x

(Don't freak out about x, it's just our place marker!!)

The reason we do 5.00 is because that's what $5 is.

So let's solve now.

6.60-5.00=1.60

So x=1.60

But you don't have to worry about x, I'm just explaining it from before.

So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.

1.60-1.00=0.60

So now we only have to figure out how to get 60 cents from any of the coins.

A quarter is 25 cents so lets use two of those

25+25=50

60=50=10

Lets recap on everything we've used so far.

We've used one $5 bill, one $1 bill, and two quarters.

Now we're going to add a dime to the mix.

A dime is worth 10 cents.

So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.

Now our second combination is going to be really easy.

We can use almost everything the exact same, we're only going to switch up the dime part.

1 dime = 2 nickles

Nickles are worth 5 cents

So we take out the dime and replace it with two nickles.

So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.

Answer/Step-by-step explanation:

29.25^2 =  855.5625

each length there is 213.89

13^2 = 169

each length here is

42.25

So a^2+b^2 = c^2 (or how i look at it leg^2 + leg^2 = H^2)

42.25^2+213.89^2 = x^2

1785.06+45,748.9321 = x^2

47533.9921 = x^2

then you square eacj side to get x to be alone.

\(\sqrt{47533.9921} \)= x

218.02 = x

Step-by-step explanation:

We use BODMAS

5/11 * -7/8 + 3/4 * 5/11 - 9/11

Multiplication first

-35/88 + 15/44 - 9/11

Addition next

-35/88 + 15/44

LCM is 88

We have

\( - \frac{35}{88} + \frac{15}{44} = \frac{ - 35 + 30}{88} \\ = - \frac{5}{88} \)

Next subtract the terms

That's

- 5/88 - 9/11

LCM is 88

We have the final answer as

\( - \frac{5}{88} - \frac{9}{11} = \frac{ - 5 - 72}{88} \\ = - \frac{77}{88} \\ = - \frac{7}{8} \)

Answer: The answer is A

Step-by-step explanation: 0.40 times 1000 is 400 and 40 percent of 1000 is 400

Answer:

D.

Step-by-step explanation:

According to the dot plot,

3 students spend 0.5 minutes brushing their teeth.

2 students spend 1.5 minutes brushing their teeth.

1 student spends 2.5 minutes brushing their teeth.

2 students spend 3.5 minutes brushing their teeth.

1 students spend 4 minutes brushing their teeth.

So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}

Median: The middle number in a set that is ordered from least to greatest.

In this example, the median is 1.5

Mean: The sum of all values divided by the number of values.

In this set there are 9 values so we’ll divide the sum by 9

In this example, the mean would be:

(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9

18 ÷ 9 = 2

If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

Answer: x= 34

Step-by-step explanation:

Given: The measurement of the angles of the quadrilateral are as

First angle=88°

Second angle=108°

Third angle= 2x°

Forth angle =(3x-6)°

Now, The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

Therefore,

Answer: x=59

Step-by-step explanation: first you would do (2x+3)×2+2x=360°

Which simplifies to 6x+6=360°

then solve to get x=59°

then substitute the x=59°

Which will then add up to 360°
