With any fraction, no matter what its denominator (bottom part), you multiply the numerators (tops) by each other and the denominators (bottoms) by each other.

For example,

$\dfrac{5}{4} * \dfrac{8}{7} = \dfrac{(5)(8)}{(4)(7)} = \dfrac{40}{28} = \dfrac{10}{7}$

Dan has five times as many $1 bills as $5 bills. he has a total of 48 bills. how many of each does he have?

Sholpan [36]

Let the number of $1 bill be x and $5 bill be y
x=5y
5y+y=48
6y=48
x=40
y=8

number of $1 bill= 40
number of $5 bill = 8

Plot point C(2,7). If M is the midpoint of CD , what are the coordinates of D?

Y_Kistochka [10]

Answer:

The coordinates of D is (-4,-9)

Step-by-step explanation:

Given

C = (2,7)

<em>M=(-1,-1) ----- Missing part of question</em>

Required

Determine the coordinates of D

<em>Let the coordinates of D be (x₂,y₂)</em>

<em>We'll solve this question using mid point formula;</em>

<em></em> $M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$ <em></em>

<em>Where</em>

$C(x_1,y_1) = (2,7)$ and $M(x,y) = (-1,-1)$

Put these values in the formula

$(-1,-1) = (\frac{2+x_2}{2},\frac{7+y_2}{2})$

By comparison;

$-1 = \frac{2+x_2}{2}$ and $-1 = \frac{7+y_2}{2}$

$-1 = \frac{2+x_2}{2}$

Multiply both sides by 2

$-2 = 2 + x_2$

Subtract 2 from both sides

$-2 -2 = x_2$

$x_2 = -4$

$-1 = \frac{7+y_2}{2}$

Multiply both sides by 2

$-2 = 7 + y_2$

Subtract 7 from both sides

$-2 - 7 = y_2$

$y_2 = -9$

<em>Hence, the coordinates of D is (-4,-9)</em>
