Answer:

10/12 can be approximated by 1

3/8 can be approximated by 1/2

so the answer to the subtraction must be really close to 1-1/2 = 1/2 = 0.5

Step-by-step explanation:

The real solution can be found by converting to numerator 24, which is the LCM, or Lowest Common Multiple of numerators 12 and 8.

10/12 = 20/24

3/8 = 9/24

Now the subtraction is (20-9)/24 = 11/24 ≈ 0.4583

So the actual result 0.4583 is actually pretty close to 0.5.

A benchmark value is nothing more than a really simple fraction or integer (1/2, 1/3, 1, 2, ...) that you know where to plot on the number line.

Making approximations can serve as a double check to see if you didn't make any mistakes on the actual calculation.

Fynjy0 [20]

The correct answer for the given question above would be the last option. The proper way to write a single digit whole number if it is in a sentence should be SPELLED OUT and not written in numerals or roman numerals. For example, I have SIX apples; and not I have 6 apples.

Find RS. A. 5 B. 10 C. 9 D. 12

777dan777 [17]

Answer:

x=9

Step-by-step explanation:

PQ + QR + RS = PS

2x-6 + 1 + x-4 = 18

Combine like terms

3x -9 = 18

Add 9 to each side

3x-9+9= 18-9

3x = 27

Divide by 3

3x/3 = 27/3

x = 9

Answer:

(4, -2) (see attached)

Step-by-step explanation:

Vector addition on a graph is accomplished by placing the tail of one vector on the nose of the one it is being added to. The negative of a vector is in the direction opposite to the original.

<h3>vector components</h3>

The components of the vectors are ...

u = (1, -2)

v = (-6, -6)

Then the components of the vector sum are ...

2u -1/3v = 2(1, -2) -1/3(-6, -6) = (2 +6/3, -4 +6/3)

2u -1/3v = (4, -2)

<h3>graphically</h3>

The sum is shown graphically in the attachment. Vector u is added to itself by putting a copy at the end of the original. Then the nose of the second vector is at 2u.

One-third of vector v is subtracted by adding a vector to 2u that is 1/3 the length of v, and in the opposite direction. The nose of this added vector is the resultant: 2u-1/3v.

The resultant is in red in the attachment.
