X= fancy, y= plain
x+y= 7
28x+ 15y=131
solve by substitution
Answer:


Step-by-step explanation:
Since y=x+1 plug it into bottom equation as y.

Subtract 1 from both sides

Subtract 5x from both sides

Divide both sides by -4

Now x=-3 into the top equation to find y

y=-2
Answer:
10.4
Step-by-step explanation:
Let the number be x
Sum of x and -3.2 : x + (-3.2) = x - 3.2
1/4 times the sum of a number and −3.2 = (1/4) * (x - 3.2)

x = 10.4
Here is a model I have made (I'm not a great artist). There are 42 circles in total, placed in 7 columns. Each column has 6 circles. This model represents 42/7 by splitting 42 into 7 parts, which are the columns, and showing that each column has 6 circles, which is the answer to 42/7.
Answer:
The mode is the least used of the measures of central tendency
