Hello there!

Here, you simply need to make sure both fractions have common denominators!

Denominator = bottom number

10 and 2 are denominators!

So, let's look at them. 10 is not the same as 2.

The ONLY way to make them the same is multiplication.

So, since 10 is the bigger number, we'll leave it alone. Let's look at 2.

Can 2 become 10? Yes! How? Multiply 2 by 5!

2 x 5 = 10

Now let's look at the fraction!

1/2 --> ?/10

If we multiplied 2 by 5, then we also have to multiply 1 by 5!

1/2 --> 5/10

So now you've got:

7/10 + 5/10

Add the numerators (top numbers) together.

7+5 = 12

When adding/subtracting, the denominators always stay the same!

12/10 = your (unsimplified) answer.

Now we have to simplify it. How? Divide the top and bottom by 2!

12/2 = 6
10/2 = 5

So your simplified answer would be 6/5 !

Hope this helped!

The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops.

Lady_Fox [76]

Answer:

$m(c(a)) = 4.8875a$

Step-by-step explanation:

The missing parameters are:

$c(a) = 4.25a$ --- Cost of marble countertops

$m(c) = 1.15c$ --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

$c(a) = 4.25a$

$m(c) = 1.15c$

$m(c) = 1.15c$ can be written as:

$m(c(a)) = 1.15*c(a)$

Substitute: $c(a) = 4.25a$

$m(c(a)) = 1.15*4.25a$

$m(c(a)) = 4.8875a$

Hence, the cost of marked up price is: $m(c(a)) = 4.8875a$

Troyanec [42]

Answer:

$Area = 60x - x^2$

Step-by-step explanation:

Given

$Perimeter = 120$

$Side\ 1 = x$

Required

The area of the garden

First, we calculate the length of the other side using:

$Perimeter = 2 *(Side\ 1 + Side\ 2)$

This gives:

$120 = 2 *(x + Side\ 2)$

Divide both sides by 2

$60 = x + Side\ 2$

Make Side 2 the subject

$Side\ 2 = 60 - x$

So, the area of the garden is:

$Area = Side\ 1 * Side\ 2$

$Area = x * (60 - x)$

Expand

$Area = 60x - x^2$
