Can you determine any purpose why these concepts are present in the pictures?
puteri [66]

The purpose why these concepts are present in the pictures is to develop imagination power among students.

As you imagine more, your mind becomes stronger and you have greater mental control. Innovation requires a strong imagination. If you succeed in what you set out to do, the same individuals who now accuse you of daydreaming will begin to aspire to be like you. Keep your aspirations high and your imagination expanding.

Imagination is a potent brain stimulant because it forces you to think differently than most people do. Your imagination can help you come up with scenarios that most effectively handle difficulties, even though your brain might classify them as being unexpected.

Answer:

For \frac{6}{25}   = \frac{d}{30} , d = 7.2

Step-by-step explanation:

Here, the given expression is \frac{6}{25}   = \frac{d}{30}

To find the value of the variable d :

\frac{6}{25}   = \frac{d}{30}  \implies d = \frac{6}{25} \times 30

or, d = \frac{180}{25}  = \frac{36}{5 }   = 7.2

Hence, for \frac{6}{25}   = \frac{d}{30} , d = 7.2

Amy and sarawong each improved their yards by planting rose bushes and ivy. They bought their from the same store. Amy spent 39$
notka56 [123]

To do this problem, you need to make a system of equations and let statements. Let x = the cost of a rose bush. Let y = the cost of a pot of ivy. 6x+3y =39. 2x+3y=27. Now, subtract the two equations to get 4x=12 (6x-2x,3y-3y,39-27) Now, divide both sides by 4 to get x = 3. Plug 3 in for x to solve y. 39-18=21. 21=3y. Y=7. 27-6=21. 21=3y. Y=7. I hope this helped! Sorry if it’s confusing.
