1 answer:

3 0

The value of the ratio is used to create the table based on comparison between two data sets.
Ratio can be rate but rate can never be ratio. In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.

the cost in dollars of a loaf of bread in a bakery is equal to 2 minus 0.25 times the number of days since it was baked. Is ther

Ierofanga [76]

We are given

Let's assume

number of days =x

the cost in dollars of a loaf of bread in a bakery =y

we have

the cost in dollars of a loaf of bread in a bakery is equal to 2 minus 0.25 times the number of days since it was baked

so, we get

$y=2-0.25x$

It will not make sense when cost is negative

so, we set y=0

and then we can solve for x

$0=2-0.25x$

We add both sides by 0.25x

$0+0.25x=2-0.25x+0.25x$

$0.25x=2$

Divide both sides by 0.25

and we get

$x=8$

So, after 8 days , the cost will become negative

which does not make sense

because cost can never be negative ............Answer

39 - 7X = —4 ( 7X +7 ) + 4 - = minus sign — = negative sign

stepan [7]

Answer:

x=-3

Step-by-step explanation:

39 - 7X = —4 ( 7X +7 ) + 4

Distribute

39 -7x = -28x -28 +4

Combine like terms

39 -7x =-28x -24

Add 28x to each side

39 -7x+28x =-28x+28x -24

39+21x=-24

Subtract 39 from each side

39-39+21x = -24 -39

21x = -63

Divide by 21

21x/21 = -63/21

x = -3
