The difference of two numbers is 16 the greater number is five less than four times a small number find the two numbers

Elis [28]

Answer:

The numbers are 23 and 7

Step-by-step explanation:

1. Set up the equations

Let x = the greater number

and y = the smaller number. Then

(1) x - y = 16

4y = 4 times the smaller number and

4y - 5 = 5 less than 4 times the smaller number. Then

(2) x = 4y - 5

You have a system of two equations:

$\begin{cases}(1) & x - y = 16\\(2) & x = 4y - 5\end{cases}$

2. Solve the equations

$\begin{array}{lrcll}(3) & 4y - 5 - y & = & 16 &\text{Substituted (2) into (1)}\\& 3y - 5 & = & 16 &\text{Simplified}\\ & 3y & = & 21 &\text{Added 5 to each side}\\(4) &y & = & \mathbf{7} &\text{Divided each side by 3} \\& x - 7 & = & 16 & \text{Substituted (4) into (1)}\\& x& = & \mathbf{23} & \text{Added 7 to each side}\\\end{array}$

The larger number is 23; the smaller number is 7.

3. Check

$\begin{array}{rclcrcl}23 - 7& = & 16 & \qquad &23&=&4(7) - 5\\16 & = & 16 & \qquad &23& = &28 - 5\\&&& \qquad &23& = &23\\\end{array}$

OK.

I have 1 hundreds, 9 tens, 9 ones, 8 tenths and 1 hundredths. What number am I?

kkurt [141]

<span>Answer: 199.81
Given:
1 hundred
9 tens
9 ones
8 tenths
1 hundredths
thus;
1 hundred = 1 x 100 = 100
9 tens = 9 x 10 = 90
9 ones = 9 x 1 = 9
8 tenths = 8 x 1/10 = 8/10 or .8
1 hundredth = 1 x 1/100 = 1/100 or .01

add: 100 + 90 + 9 + .8 + .001 = 199.81
That is: one hundred ninety-nine and eighty-one hundredths</span>
