A florist prepares an order of daisies and roses. For every 5 daisies she orders 2 roes. What 2 equations show the relationship
Vsevolod [243]

Answer:

d = 2.5r and r = \frac{d}{2.5}

Step-by-step explanation:

Given

5 daises to 2 roses

Required

Determine the relationship between them

The question shows a direct proportion between number of daises and roses.

i.e.

d\ \alpha\ r

Where d = daises and r = roses

Convert the above expression to an equation

d = kr

Make k the subject

k = \frac{d}{r}

When d = 5 and r = 2;

k = \frac{5}{2}

k = 2.5

So, the first relationship between d and r can be gotten by substituting 2.5 for k in d = kr

So:

d = 2.5 * r

d = 2.5r ----------- (1)

Make r the subject in (1)

r = \frac{d}{2.5} ------------------------(2)

Hence, the relationships between d and r are:

d = 2.5r and r = \frac{d}{2.5}

Is it true that when we multiply a number by 3, we get the same value as if we added 6 to that number.
seraphim [82]

Answer:

True

Step-by-step explanation:

Multiplying a number by 3 will produce the same value as adding 6 to that number can be expressed algebraically as:

3x = x + 6

In order to determine whether the given statement is true, we can solve for x:

Start by subtracting x from both sides:

3x - x = x - x + 6

2x = 6

Divide both sides by 2:

2x/2 = 6/2

x = 3

Substitute the value of x into the original equality statement:

3x = x + 6

3(3) = 3 + 6

9 = 9 (True statement).

Therefore, it is true that when we multiply a number by 3, we get the same value as if we added 6 to that number.
