Question

camilla has a large number of basketball cards. she gave half to her friend and 1/sixth to her brother . she has 150 left . How many did she have to start?

Answer 1

Here is your answer
Let the total number of cards are X

Her friend = X /2
Her brother = X /6
She left. = 150

ATQ
X/2 + X/6 +150 = X

3X + X + 150x 6 = 6X
6X - 4X = 900
2X = 900
X = 900/2
X = 450

SO SHE HAS 450 CARDS Answer

Hope it helps you

Answer 2

Concept:

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

Given:

camilla has a large number of basketball cards. she gave half to her friend and 1/sixth to her brother . she has 150 left

Find:

How many did she have to start?

Solution:

Let the total number of cards are X

Her friend = X /2

Her brother = X /6

She left. = 150

As per question,

⇒X/2 + X/6 +150 = X

⇒3X + X + 150x 6 = 6X

⇒6X - 4X = 900

⇒2X = 900

⇒X = 900/2

⇒X = 450

Therefore, she has 450 cards
