You add 3.5 to both sides to get rid of it. Then you have 16=2g, you divide 2 from both sides and get g=8

Answer:

$x=2\ or\ x=5\Rightarrow(2,\ 0)\ \vee\ (5,\ 0)$

Step-by-step explanation:

$f(x)=x^2-7x+10\\\\\text{The zeros of the parabola}\ f(x):\\\\f(x)=0\to x^2-7x+10=0\\\\\left\begin{array}{ccc}a+b=-7\\\\ab=10\end{array}\right\}\Rightarrow a=-2,\ b=-5\\\\x^2-2x-5x+10=0\qquad\text{use the distributive property}\\\\x(x-2)-5(x-2)=0\\\\(x-2)(x-5)=0\iff x-2=0\ \vee\ x-5=0\\\\x-2=0\qquad\text{add 2 to both sides}\\x-2+2=0+2\\\boxed{x=2}\\\\x-5=0\qquad\text{add 5 to both sides}\\x-5+5=0+5\\\boxed{x=5}$

<em>Greetings from Brasil...</em>

Before comparing mixed fractions, let's make them inappropriate

2 1/2 = 5/2

3 1/3 = 10/3

Comparing fractions. (MMC - Maximum Common Multiple -<em> I don't know that term in English</em>)

2 1/2 = 5/2 = 15/6

3 1/3 = 10/3 = 30/6

30/6 > 15/6 then

<h2>3 1/3 > 2 1/2</h2>

Answer:

Grapes 12 lbs

Apples 20 lbs

Oranges 6 lbs

Cantaloupe 15 lbs

Peaches 15 lbs.

Step-by-step explanation:

Sammy has bought 12 lbs of Grapes.

Now, weight ration of Apples to Grapes is 5 : 3

Therefore, he bought Apples of $\frac{12 \times 5}{3} =20$ lbs

The wight ration of Grapes to Oranges is 4 : 2

Therefore, he bought Oranges of $\frac{12 \times 2}{4} =6$ lbs

Again, the weight ratio of Cantaloupe to Apples is 3 : 4

Therefore, he bought Cantaloupe of $\frac{20 \times 3}{4} =15$ lbs

Finally the weight ratio of Oranges to Peaches is 2 : 5

Therefore, he bought Peaches of $\frac{6 \times 5}{2} =15$ lbs
