Answer:
0.75
Step-by-step explanation:
The problem deals with fractions comparison, lets do it:
21/30 > 2/3
we begin solving:
21 > (2/3)*30
21 > 2*10
<span>21 > 20
</span>therefore the proposed inequality is true, <span>21/30 > 2/3
You can solve as well getting same denominator for both fractions and comparing directly, in this case we need to get 2/3 to be divided by 30:
2/3 = (10/10)(2/3) = 20/30
So we have:
</span><span>21/30 > 2/3
</span>which is equal to:
<span>21/30 > 20/30
</span>and we compare directly because both fractions are divided by the same number, and we can see that the inequality is true.
The answer is ou need to rewrite the equation to make it easy... and let it equal zero
<span>2<span>x2</span>−8x+4=0</span>
which will become
<span>2(<span>x2</span>−4x+2)=0</span>
you need to solve
<span><span>x2</span>−4x+2=0</span><span>
by completing the square or the general quadratic formula.</span>
Eight fortyfive would most likely be the answer
The number of roses purchased will be; <em><u>12 roses</u></em>
The total cost of the bouquet is; <em><u>$51</u></em>
Let number of roses be x
For Summerfield florists;
At $1 per rose and $39 for the vase, cost is;
C = x + 39
For grayson's flowers;
At $3 per rose and $15 for the vase,total cost is;
C = 3x + 15
We are told when he orders a certain number of roses, the cost will be the same with each flower shop.
Thus;
x + 39 = 3x + 15
3x - x = 39 - 15
2x = 24
x = 24/2
x = 12
Total cost is;
C = 12 + 39
C = $51
