Answer:Group of answer choices

Step-by-step explanation:

What you first want to do is like and unlike terms so basically liketerms are terms withthe same sign and unlike terms are terms with diferent signs for instinse 3g and 2g are like terms so -33 and -9 and -9 and 9 are unlike terms so you just have to find the like and unlike terms to answer the question!

Answer: -9

Step-by-step explanation: Let's solve your equation step-by-step.

3g+15−12+3−2g+4=1

Step 1: Simplify both sides of the equation.

3g+15−12+3−2g+4=1

3g+15+−12+3+−2g+4=1

(3g+−2g)+(15+−12+3+4)=1 (Combine Like Terms)

g+10=1

g+10=1

Step 2: Subtract 10 from both sides.

g+10−10=1−10

g=−9

So the answer is g=-9

Answer:

Step-by-step explanation:

Answer:

Well for example most video games cost $60, so if you divide the original price by 100 and multiply it by 30, you'll get 18, so you take away that from 60, then you'll get 42.

Step-by-step explanation:

60 divided by 100 = 0.6, times that by 30 = 18, take away that from the original price which was 60, you'll get 42.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

If the cost of the video game is $60

The cost of the video game after 30% off is $42

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

We will assume that the cost of the video game = $60

Percentage off = 30%

30% = 30/100

30% of 60 = 30/100 x 60 = 18

The cost after 30% off.

= $60 - 30% of $60

= 60 - 30/100 x 60

= 60 - 18

= $42

Thus,

If the cost of the video game is $60

The cost of the video game after 30% off is $42

Answer:

The farmer has 45 chickens.

Step-by-step explanation:

Let x = number of chickens

Let (66-x) = number of pigs

Pigs have 4 legs = 4(66 - x)

Chickens have 2 legs = 2x

4(66-x) + 2x = 174

= 264 - 4x + 2x = 174

= -4x + 2x = 174 - 264

= -2x = -90

= x = 45 <-- number of chickens

number of pigs: 66 - x

66 - 45 = 21

just to check!

(45 x 2) + (21 x 4) = 174

Answer:

The farmer has 45 chickens

Step-by-step explanation:

Let the number of pigs = p

Let the number of chickens = c

Total animals = 66

p + c = 66 ---------------------(I)

c = 66 - p

A pig has 4 legs. so 'p' number of pigs has p*4 = 4p legs

A chicken has 2 legs. so 'c' number of pigs has c*2 = 2c legs

Total legs = 174

4p + 2c = 174 --------------------(II)

Substitute c = 66 -p in equation (II)

4p + 2(66 - p) = 174

4p + 2*66 - 2*p = 174

4p + 132 - 2p = 174

4p - 2p + 132 = 174             {Combine like terms}

       2p + 132 = 174                     {Subtract 132 from both sides}

             2p    = 174 - 132          

             2p     = 42                       {Divide both sides by 2}

                p  = 42/2

               p = 21

Plugin p =21 in equation (I)

21 + c = 66

        c = 66 -21

c = 45

The farmer has 45 chickens

Answer:

The answer could be 4 out of 8 which is 1/2

Answer:

12 of the 5 cents stamps,

20 of the 6 cents stamps

15 of the 8 cents stamps

10 of the 30 cents stamps.

Step-by-step explanation:

Let's name:

x = number of 5 cent stamps,

w = number of 6 cent stamps,

y = number of 8 cent stamps,

z = number of 30 cent stamps,

Create the following system of equations based on the info provided:

z + 5 = y

w = 2 * z

x = 12

600 = 5 (12) + 6 w + 8 y + 30 z

replace everything in terms of "z":

600 = 60 + 6 (2 * z) + 8 (z + 5) + 30 z

540 = 12 z + 8 z + 40 + 30 z

500 = 50 z

z = 10

and now we can find the rest:

y = 5 + 10 = 15

w = 2 * 10 = 20

Therefore there are:

12 of the 5 cents stamps,

20 of the 6 cents stamps

15 of the 8 cents stamps

10 of the 30 cents stamps.

P.S I TRIED MY BEST

Step-by-step explanation:

The required values of ratios are 9/16,3/2, 7/6 and 1/12 respectively. The only false option is (c).

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

All the options are examined one by one as follows,

(a) The ratio of 5/8 to 10/9 is given as,

5/8 : 10/9

= (5/8) ÷ (10/9)

= 5/8 × 9/10

= 9/16

Thus, it is true.

(b) The ratio of  4/7 ∶ 8/21 is given as,

4/7 ∶ 8/21

= (4/7) ÷ (8/21)

= 4/7 × 21/8

= 3/2

Thus, it is true.

(c) The unit rate of 7/9 and 2/3 equivalent to the ratio given below,

7/9 : 2/3

= 7/9 ÷ 2/3

= 7/9 × 3/2

= 7/6

Thus, it is false.

(d) The unit rate of 9/16 and 27/4 equivalent to the ratio given below,

9/16 : 27/4

= 9/16 ÷ 27/4

= 9/16 × 4/27

= 1/12

Thus, it is true.

Hence, the ratios for the given options are obtained as 9/16,3/2, 7/6 and 1/12 respectively.
