Answer:

x = 3/2

Step-by-step explanation:

7 1/4 = 7 + 1/4 = 28/4 + 1/4 = 29/4

9 3/8 = 9 + 3/8 = 72/8 + 3/8 = 75/8

then:

7 1/4 x = 29x/4

29x/4 - x = 75/8

29x/4 - 4x/4 = 75/8

25x/4 = 75/8

x = (75/8)/(25/4)

x = (75*4)/(8*25)

x = 300/200

x = 3/2

Checking:

(29/4)(3/2) = (29*3)(4*2) = 87/8

87/8 - 3/2 = 75/8

3/2 = 12/8

then:

87/( - 12/8 = 75/8

Social Security numbers are of the form XYZ - MN - ABCD

Part A:

The first three digits XYZ are referred to as the area number

X is a number 1 - 7 (1, 2, 3, 4, 5, 6, 7)

That means we have 7 choices for X

Y and Z can be any number 0 - 9 (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

That means we have 10 choices for Y and also 10 choices for Z

So, the number of possible ways are

$7\times10\times10=700$

But we know that the area code 666 has never been used.

So we need to subtract this one from the total.

$700-1=699$

Therefore, the total number of possible area codes is 699.

Answer:

9 hundreds

9 tens

9 ones

Step-by-step explanation:

in math, every digit in a number has a place value.

Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.

The place values to the left of the decimal point are increasing powers of 10:

The first place to the left of the decimal point is the ones place, or 10^0.

The second place to the left of the decimal is the tens place, or 10^1.

The third place to the left of the decimal is the hundreds place, or 10^2.
