$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Find the value of x.

$\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}$

Given,

DE || AB
AD = 2x
CD = x + 3
BE = 2x - 1
CE = x

Value of x (CE) = ?

__________________

We can solve this question using the Basic Proportionality Theorem (BPT). According to BPT, if a line is drawn parallel (||) to 1 side of a triangle to intersect the other 2 sides in 2 distinct points then the other 2 sides will be divided in the same ratio.

__________________

So in this triangle,

$\tt\frac{CD}{AD} = \frac{CE}{BE} \\$

Then,

$\tt \frac{x + 3}{2x} = \frac{x}{2x - 1} \\ \\ \sf \: Using \: cross \: multiplication.... \\ \\ \tt \: x + 3(2x - 1) = x(2x) \\ \tt \: x(2x - 1) + 3(2x - 1) = {2x}^{2} \\ \tt \: {2x}^{2} - x + 6x - 3 = {2x}^{2} \\ \\ \sf Cancel \: out \: 2 {x}^{2} \: from \: both \: the \: sides \\ \\ \tt \: - x + 6x - 3 = 0 \\ \tt \: - x + 6x = 3 \\ \tt \: 5x = 3 \\ \large\boxed{\boxed{\bf \: x = \frac{3}{5} }}$

The drawing shows a stack of alternating cups. The cups are 9.2 cm high. How many cups will fit in a door that is 211.77 cm high

KIM [24]

Answer:

The total number of whole cups that we can fit in the dispenser is 25

Step-by-step explanation:

It is given that the height of each cup is 20 cm.

But when we stack them one on top of the other, they only add a height of 0.8 to the stack.

The stack of cups has to be put in a dispenser of height 30 cm.

So we need o find out how many cups can fit in the dispenser.

Since the first cup is 20 cm high, the height cannot be reduced. So the space to fit in the remaining cups in the stack is only 30-20 cm as that’s the remaining space in the dispenser

So,

30 - 20 = 10 cm

To stack the other cups we have 10 cm of height remaining

As we know that addition of each adds 0.8 cm to the stack, the total number of cups that can be fit in the dispenser can be calculated by the following equation. Let the number of cups other than the first cup be denoted by ‘x’.

10 + 0.8x = 30

0.8x = 20

x = 25

The total number of cups that we can fit in dispenser is 25
