A mean is an average of a total. If you add all the pets together and divide by the number of people, you get the mean. So 1 +3 + 2 + 4 + 0 = 10

You have 10 pets in total.

There are 5 people.

Mean = 10 pets / 5 people = 2 pets per person. that's the mean or average that everyone has.

Jamie takes at random a counter from the bag and records the colour. Red : blue : green = 1:3:7 Jamie does this a number of time

Sonbull [250]

Answer: There are 249 times Jamie takes a counter from the bag.

Explanation:

Since we have given that

Ratio of colour of red to blue to green is 1:3:7.

Number of blue counters = 68

Let the total number of times Jamie does from the bag be x.

So, According to question,

$\frac{3}{11}\times x=68\\\\x=\frac{11}{3}\times 68\\\\x=249.33\\\\=249\ approx.$

Hence, there are 249 times Jamie takes a counter from the bag.

Solve the system of equations.

Alenkasestr [34]

Step-by-step explanation:

<u>Step 1: Substitute x from the second equation into the second one</u>

$2x - 9y = 14$

$2(-6y + 7) - 9y = 14$

$(2 * -6y) + (2 * 7) - 9y = 14$

$-12y + 14 - 9y = 14$

$-21y +14 - 14 = 14 - 14$

$-21y/-21 = 0 / -21$

$y = 0$

<u>Step 2: Substitute y into the second equation</u>

$x = -6y + 7$

$x = -6(0) + 7$

$x = 0 + 7$

$x = 7$

Answer: $x = 7, y = 0$

Any help I would really appreciate it

DanielleElmas [232]

Answer:

C and D

Step-by-step explanation:

You can tell if equations have no solution if the variables on both sides of the equation are the same.

Choice C is 10+6x=15+9x-3x. You would combine 9x and -3x, turning the equation into 10+6x=15+6x. Since there is a 6x on both sides, Choice C would have no solution.

The same for Choice D. When you simplify everything there is a 3x on both sides, so it would have no solution.

5x-y=1/4 intercept form

MAVERICK [17]

5x - y = 1/4; this equation is written in slope - intercept form

Slope - Intercept form formula: y = mx + b

-Move '5x' to the left side of the equation
-Move 'y' to the right side of the equation

y = 5x - 1/4
