[Hello,BrainlyUser]

Answer:

9/10

Step-by-step explanation:

7/10 + 2/10 When add we need to have same denominator. Thus, this question have same denominator so we don't have to worry about that.

Now we have to add the numerator.

If you don't know what are numerator and denominator then let me tell you.

Numerator is the Top Number on the fraction

Denominator is the Bottom Number on the fraction.

In this question, Numerator = 2 ,Denominator = 10 and Numerator = 7 and Denominator = 10 .

Now Adding the numerator:

2 + 7 = 9

We don't add the denominator [ Stay the same]

9/10 is the Answer.

9/10 is already in simplest form.

The volume of a medal is 35 cm³
ratelena [41]

Answer:

301.224 g

Step-by-step explanation:

Let's divide in the ratio 21:4 the volume of the medal (35cm^3)

copper = (21/25)(35cm^3) = 29.4cm^3

tin = (35 - 29.4)cm^3 = 5.6cm^3

<em>FOR THE COPPER</em>

8.84 : 1 = X : 29.4

X = 259.896(g)

<em>FOR THE TIN</em>

7.38 : 1 = X : 5.6

X = 41.328(g)

<em>(259.896 + 41.328)g </em><em>=</em><em> 301.224 g</em>

3 + 9 = 4.5x - 1.5x
