Answer: Tom has 3/10 of his room left to finish painting. The third choice is correct.

Explanation: Let’s write this as an equation.

Let x be the fraction of room that Tom has left to finish.

(3/5 + 1/10) + x = 1

Rewrite 3/5 as 6/10 so that it has a common denominator with 1/10.

(6/10 + 1/10) + x = 1

Combine like terms.

7/10 + x = 1

Subtract 7/10 from both sides.

x = 3/10

Therefore, since we know x = 3/10, we know that Tom has 3/10 of his room left to finish painting. The third choice is correct.

Answer:

3/10

Step-by-step explanation:

3/5 + 1/10

3/5 = 6/10

6/10 + 1/10 = 7/10 = total bedroom space he painted

10/10 - 7/10 = 3/10 = how much space is left

Answer = 3/10

Sarah has 273 feet of wire to make bead necklaces. If each necklace requires 1 2/3 feet of wire, how many necklaces can she make
o-na [289]

Oh boy, here we go again

First we must convert  1 2/3 to an improper fraction.  By doing this, we get 5/3  (3/3 + 2/3)

So now we have 273 /  5/3

To divide this easier we can do something that when I learned it was called (keep, change, flip)  which basically means keep the first fraction, change the sign from division to multiplication, and flip the second fraction

This now turns into:  273/1 * 3/5

Combine 273 and 3/5

273⋅3/5

Multiply 273

by 3

819/5

is your answer

If z varies inversely as w, and z= 3 when w=4, find z when w=2.<br> Z=
vivado [14]

Answer:

6

Step-by-step explanation:

Inverse proportion.

z = k/w

z = 3, w = 4

Solve for k constant.

3 = k/4

(4)3 = (4)k/4

12=k

The value of k constant is 12.

z = k/w

Put w as 2 and k as 12 and solve for z.

z = 12/2

z = 6

The value of z when w equals 2 is 6.
