All you have to do is move the denominator on the other side, by multiplying.

a-10
------- = -9
20

multiply 20 x -9
= -180

then it becomes a-10=-180
+10 +10
a=-170

Ok!
The answer is a = -170.

First, multiply 20 on both sides.
Next, add the 10 on both sides. This will leave you with a being equal to -170 :)

Tanya has 442 pennies. If she gives away 128 of the pennies equally to 4 friends, about how many pennies will Tanya give each

butalik [34]

Answer:

32 pennies to each friend and 314 pennies remaining

Step-by-step explanation:

For the first step, we need to divide 128 by 4 to get the amount of pennies she gave to each friend: 128/4 = 32

For the second step, we need to subtract 128 from 442 to find out how many pennies she has left: 442-128 = 314

Hope this helps!

Find the distance of the point (3,4) from the midpoint of the line joining (8,10) and (4,6)

Elis [28]

Answer:

Distance between point $(3,4)$ and midpoint of line joining $(8,10)$ and $(4,6)$ = $5$ units.

Step-by-step explanation:

Given:

Points:

$A(3,4)\\B(8,10)\\C(4,6)$

To find distance from point A to midpoint of BC.

Midpoint M of BC:

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\$

$M=(\frac{8+4}{2},\frac{10+6}{2})\\$ [Plugging in points $B(8,10)\ and\ C(4,6)$ ]

$M=(\frac{12}{2},\frac{16}{2})\\$

$M=(6,8)\\$

Distance between A and M:

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\$

$D=\sqrt{(6-3)^2+(8-4)^2} \\$ [Plugging in points $A(3,4)\ and\ M(6,8)$ ]

$D=\sqrt{(3)^2+(4)^2} \\$

$D=\sqrt{9+16} \\$

$D=\sqrt{25} \\$

$D=\pm5$

Since distance is always positive ∴ $D= 5$ units
