B. Complete the diagram to find the unit rate for the 5-class block.What is the cost per class?

Answer:

y= _3x+55

Step-by-step explanation:

we conqet two points
(0,55)  (12,19)

55=B                       subsiquent two points into the equation
19=a,12+55
a=-3
b=55
so we choose B

-175°C

hope helpful <3

-175 degrees because it is grater than -173 degrees C

Answer:

1. $548.90

2. $349.30

3. $160,650

4. 580

5. 20.14%

6. 64.8%

Answer:

x = 13/12

x = 1 1/12

Step-by-step:

4 (x + 1 1/3) = 9 2/3

4x + 5 1/3 = 9 2/3

subtract 5 1/3 from each side

4x = 4 1/3

divided by 4 on each side

x = 13/12

x = 1 1/2

Answer:

y = 245 / 7, x = 29

Step-by-step explanation:

make both into ax + by = c format which is

Math:

5x + 2y = 245

-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.

[(Side Note) if both were positive then you would need to do

EX: - 5 (- x + y = 6)]

Continued:

7y = 275 ==> 7y/7 = 245/7

y = 245 / 7

Plug it in the most convenient one which has the equation y = x + 6

and tweak it a bit

x = y - 6

x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7

x = 203 / 7 ==> 29

Answer:

49

Answer:

/24

Step-by-step explanation:i am not that good but to me looks like /24 i hope it is a good A :}

Answer:

Square Root of 26 = 5.9

Square Root of 20 = 4.7

Square Root of 24 = 4.8

Square Root of 27 = 5.1

So, C, Square Root of 24 is the correct one!

1. How many cups of seed does Zack need to fill both bird feeders? Show how you found your answer

    [] He will need 5 cups of seed to fill both bird feeders

1. How many cups of seed does Zack need to fill both bird feeders? Show how you found your answer

*  He  needs  5 cups of seed to fill both bird feeders .

steps :  2 1/2 * 2

= 5

2. Write an expression for the number of scoops Zack needs to fill both feeders

  If the  scoop hold 1/4 cup , no matter how many scoops (unknown )should equal 5.

steps : 1/4x = 5

3. Evaluate the expression to find the number of scoops Zack needs. Show your work

*  20 scoops

*  steps : 1/4x =

5 -> x = 20

hope it  helps have a good day :>  

The open side of the inequality sign indicates the larger number. So 5 > 3, 4 < 6.

This, ≥, means it is bigger than or equal.

To show < or >, the purple arrow points to where the unknown value (x or n or k or b etc.) could be, and the dot is unfilled, or white, indicating that number is not a possible value of the unknown number.

To show ≤ or ≥, the purple arrow works the same way, it points to the where the unknown value could be. But the dot is filled, showing that the number could be the unknown value.

So for question 11, the answer is x ≤ 0 (x is less than or equal to zero).

For question 12, the answer is x > 3 (x is more than three)

Hope this helped :)

( D.)

Step-by-step explanation:

Answer:

159,100 is the answer

Step-by-step explanation:

159,100 is the answer because 159,095 is closest to 159,100 than 159,000. So therefore, 159,100 is the answer.

Answer:

159,100

Step-by-step explanation:

200,000 - rounded to the nearest hundred thousands

160,00 - rounded to the nearest ten thousands

159,00 - rounded to the nearest thousands

159,100 - rounded to the nearest hundreds

159,100 - rounded to nearest tens

159,095 - rounded to nearest ones

While rounding off to the nearest hundred, if the digit in the tens place is between 0 – 4 i.e. < 5, then the tens place is replaced by ‘0’.

If the digit in the units place is equal to or >5, then the tens place is replaced by ‘0’ and the hundreds place is increased by 1.

Answer: The answer is B.

Step-by-step explanation:

To figure out, you must first turn the mixed fraction (3 1/2) into an improper fraction (7/2). We can do so by:

3 * 2 = 6

6 + 1 = 7 or 7/2

Next, you follow the rules of KCF: Keep, Change, Flip. Keep the first fraction, Change the sign to its inverse operation, and Flip the second fraction.

Our original equation is 7/2 /(divided by) 3/2 = ?

1. Keep the first fraction

7/2 / 3/2 = 7/2 / 32

2. Change the sign to its inverse operation

7/2 / 3/2 = 7/2 * 3/2

3. Flip the second fraction

7/2 * 3/2 = 7/2 * 2/3

Now, solve.

7/2 * 2/3

7 * 2 / 2 * 3 = 14/6

To make this a proper mixed number, first simplify.

14/6 / 2 = 7/3

Now, figure out how many wholes are in 7/3.

7/3 / 3 = 2 1/3

This is because 2 times 3 is six, and 7 minus 6 equals 1, or 1/3.

Therefore, the answer is 7/3 OR 2 1/3 OR B

Answer:

Craig has

$25−$5.25 for shoes. In other words, he has $19.75 Now when you divide this amount by $4.00, you will get numbers of games he played.

$19.75

$4

=4.9375

or only 4 games.

Step-by-step explanation:

Answer: 4 games

Step-by-step explanation: 25-5.25=19.75

19.75 divided by 4 = 4.9375 (but let's say its 4)

Or you could use the subtraction way 19.75 - 4 and continue until you cant subtract it by 4 anymore

The changes he be left with us $3.75

72 = 72

Hope this helps!

Answer:

n-4 = 12

Step-by-step explanation:

So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.

845 = 45n + 125.

Subtract from both sides:

845-125 = 45n + 125-125

720 = 45n

Divide by 45:

720 / 45 = 45n / 45

16 = n

This means that 16 bracelets can be made if the cost is 845.

We can also re-input the information into the equation to be extra sure!

845 = 45 (16) + 125.

845 = 720 + 125.

845 = 845

Yes!

I hope this helps! :)

Answer: Alright i know exactly how to do this :) i need ur help though it's been a bit since i did this the types they are asking for what are they?

I need a multiple choice otherwise i dunno how to help with identifying them

The math is simple tho

16x-2=15x+4

add 2 to -2 to elimate itself add 2 to +4 =6

16x=15x+6

we need x by itself subtract 15x from itself and then 16x

1x=+6 = x is 6

The rest go the same-
