12) Twenty cubic feet of marble can weigh 3400 pounds, plus or minus 100

andrezito [222]

Answer:

Let's suppose that one cubic foot of marble is x.

20x = 3400

But because the weight has a range of +-100, then 20x is between 3300 and 3500. Write it like this:

3300<20x<3500

Divide by 20:

165<x<175

The meaning of this is that one cubic foot of marble weight between 165 and 175 pounds

Since we have given that

Number of equal groups = 5

Let the total number of socks be 's'.

According to question, expression will be

Now, Suppose number of socks in each group = 4

So, it will become,

Suppose number of socks in each group = 15

So, Total number of socks become

Sarah and Owen Herbert purchased 26 stamps, a mixture of 49 cents and 34 cents stamps. Find the number of each type of stamp if

Hunter-Best [27]

Let $A$ be the number of 49 cent stamps bought and $B$ be the number of 34 cent stamps bought. We can set up the following equations using the information above:

$A + B = 26$

$0.49A + 0.34B = 11.39$

Substituting the first equation into the second equation will give you the following:

$0.49(26 - B) + 0.34B = 11.39$

Solving for B will give you the number of 34 cent stamps purchased, and then you can figure out the number of 49 cent stamps purchased.
