The length of a rectangular garden is 7 meters longer than its width. if its perimeter is ( 12 x + 14) meters, find its length i

cluponka [151]

L=7+w
P=(12x+14)=2(6x+7)
l+w= P/2 = 2(6x+7)/2= 6x+7
l+w=6x+7
2l = 6x+7
l = (6x+7)/2
l=7+w
-> w= l-7
= [(6x+7)/2] -7
= (6x+7-14)/2
= (6x-7)/2

A number divided by three less two is at most two

Marina CMI [18]

x ≤ 12

Solution:

Let us take the number be x.

A number : x

A number divided by three : $$\frac{x}{3}$

A number divided by three less two : $$\frac{x}{3}-2$

A number divided by three less two is at most two : $$\frac{x}{3}-2\leq 2$

Now, simplify the inequality,

$$\Rightarrow\frac{x}{3}-2\leq 2$

Add 2 on both sides of the inequality,

$$\Rightarrow\frac{x}{3}-2+2\leq 2+2$

$$\Rightarrow\frac{x}{3}\leq 4$

Multiply by 3 on both sides of the equation,

$$\Rightarrow\frac{x}{3}\times3\leq 4\times3$

$$\Rightarrow x\leq 12$

Hence x ≤ 12.
