forty-seven marbles are shared between some children. each child receives six marbles and there are five marbles left over. how
Nadya [2.5K]

The total number of children can be calculated using linear equation in one variable. The marbles are shared among 7children.

<u>Solution</u>

Total number of marbles = 47

The number of marbles received by each child = 6

Let the number of children be x

Then according to the question'

Total number of marbles received by all children + 5 = Total number of marbles

6x + 5 = 47

6x = 47- 5

6x = 42

x = 7

now, the number of children is 7.

<h3>What is linear equation in one variable?</h3>
  • An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.
  • A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C.
  • Here, the variables x and y, the coefficients A and B, and the constant C are all present.
  • A linear equation's graph will always be a straight line.
  • One-variable linear equations are fairly simple to solve. To determine the value of the unknown variable, the variables are divided and placed on one side of the equation, and the constants are combined and placed on the other side.

The perimeter of a right angled triangle is 56 cm and its hypotenuse is 25 cm. Find the area of triangle.​
Daniel [21]
Perimeter = 56
Hypo = 25
So 56-25 = 31 (for two side)
for one side = 31/2 = 15.5

so area = 1/2 x base x height

When adding two numbers, such as 123 and 423, care is taken to first line them up and then add like digits. How does expanding t
Ivanshal [37]
Since a polynomial is where we have like terms such as (1 x 10²) and (4 x 10²), we can add these up using the distributive property to get (5 x 10²) but still keep the 10². For example, it's similar to if we had 2x²+3x²=5x². The x² is still there, but we add up the 2 and 3. Similarly, we can add these up for 10^1 and 10^0
