Answer:

4 bags cost 12 = 3 each bag so 3 x 7 = 21$

Step-by-step explanation:

Answer:

2/5

Step-by-step explanation:

You divide 12 by 6 and 30 by 6.

PLEASE MARK BRAINLIEST!!!!

The fraction 12 / 30 in the simplest form is 2 / 5.

Fractions are numbers that are written in 2 parts: a numerator and a denominator.

The upper part is the numerator while the lower part is the denominator.

Therefore, let's solve the fractions to it simplest form.

Simplified fractions are the fractions in their lowest, reduced and simplest form.  In other words, a fraction is said to be in its simplest form if 1 is the only common factor of its numerator and denominator.

Therefore,

12 / 30 ÷ 6 / 6 = 2 / 5

Answer:

x = 20

Step-by-step explanation:

these angles are supplementary, which means they add up to 180°

using this, you can make the following equation:

6x + 60 = 180

subtract 60 from both sides of the equation

6x + 60 - 60 = 180 - 60

6x = 120

divide both sides of the equation by 6

6x/6 = 120/6

x = 20

Answer:

x = -18

Step-by-step explanation:

Step 1: Define

w(x) = 5/6x - 3

w(x) = -18

Step 2: Substitute and Evaluate

-18 = 5/6x - 3

-15 = 5/6x

x = -18

Answer:

The pounds of roasted pistachios nuts Christopher purchases is 10 pounds

Step-by-step explanation:

The given parameters are;

The price of raw almonds at Nuts.com = $8 per pound

The price of roasted pistachios at Nuts.com = $9 per pound

The amount Christopher spends on Nuts = $162

The quantity of nuts Christopher purchase = 19 pounds

Let the pounds of raw almonds nuts Christopher purchases = X and the pounds of roasted pistachios nuts Christopher purchases = Y

∴ $8·X + $9·Y = $162...(1)

X + Y = 19...(2)

Making X the subject of the formula in equation (2), we have;

X = 19 - Y

Substituting the value X in equation (1) gives;

$8·(19 - Y) + $9·Y = $162

$152 - $8·Y + $9·Y = $162

$1·Y = $162 - $152 = $10

Y = $10/($1) = 10

Y = 10 pounds

The pounds of roasted pistachios nuts Christopher purchased = Y = 10

The pounds of roasted pistachios nuts Christopher purchases = 10 pounds

X = 19 - Y = 19 - 10 = 9

X = 9 pounds

The pounds of raw almonds nuts Christopher purchases = X = 9

The pounds of raw almonds nuts Christopher purchases = 9 pounds

Answer:

One solution, as there is only one intersection between these two lines.

x = 2, and y = 1 (point of interesection (2, 1) )

y = 2x-3

y = -x + 3

first step is to substitute the y of one equation into the other and solve for x.

- x + 3 = 2x - 3

___________

+x. +x

3 = 3x-3

2 = x

______________

x = 2

_______________

We can verify this value is true by substituting it back into the equations and as a result also solving for the working y value.

x = 2 -> y = 2(x) - 3

2(2) - 3 = 4 - 3 = 1

y = 1

____________

x = 2 -> y = -(x) + 3

-(2) + 3 = -2 + 3 = 1

y = 1

Looks like the slope is -(1/2) and the equation is y= -(1/2)x + 1

Answer:

5 cm/s

Step-by-step explanation:

The rate of change (ROC) is the speed at which the y variable (hieght) increases with the x variable (time). so ROC = 5.

the linear equation is y = mx + b, m is also the roc, b is the initial value, so,

if y = 60, x = 4 & b = 40, then making m the subject of equation will give the value of the ROC. i.e m = (y - b)/x = (60 - 40)/4.

Answer:

The mean age of the frequency distribution for the ages of the residents of a town is 43 years.

Step-by-step explanation:

We are given with the following frequency distribution below;

    Age                      Frequency (f)               X                    

    0 - 9                            30                         4.5                   135

   10 - 19                           32                        14.5                  464

   20 - 29                         12                         24.5                 294

   30 - 39                         20                        34.5                 690

   40 - 49                         25                        44.5                1112.5

   50 - 59                         53                        54.5                2888.5

   60 - 69                         49                        64.5                3160.5

   70 - 79                          13                         74.5                968.5

   80 - 89                          8                          84.5                676        

   Total                            242                                              10389      

Now, the mean of the frequency distribution is given by the following formula;

                         Mean =  

                                    =    = 42.9 ≈ 43 approx.

Hence, the mean age of the frequency distribution for the ages of the residents of a town is 43 years

Answer:

1:6 or 1/6

Step-by-step explanation:

Because the question asks for the goats to the total number of animals, you have to write the ratio in the same order. So, there are 4 goats, and to find the total number of animals, you just add every number.

5+11+4+4=24

The result would be 4:24, and because you need the ratio in the simplest form, you just divide both sides by the same greatest number. Both 4 and 24 can be divided evenly by 4. So, when you simplify, the answer comes out as 1:6. (Ratios can also be written as fractions, just so you know!! For example, the ratio 1:6 can be written as 1/6; both answers would be correct.)
