<em>Hey There!!</em>
<em>The answer is below!!</em>
Step-by-step explanation:
We move all terms to the left:
We add all the numbers together, and all the variables
We get rid of parentheses
After that, We add all the numbers together, and all the variables
Then, We move all terms containing n to the left, all other terms to the right
<em>I don't know this is </em>
% right....

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
Answer:
b>-18
Step-by-step explanation:
inequality form:b>-18
interval notation:(-18,inf.)
-2y + 5z = -3
y = -5x - 4z - 5
x = 4z + 4
-2(-5(4z + 4) - 4z - 5) + 5z = -3
-2(-20z - 20 - 4z - 5) + 5z = -3
-2(-20z - 4z - 20 - 5) + 5z = -3
-2(-24z - 25) = -3
48z + 50 = -3
<u> - 50 - 50</u>
<u>48z</u> = <u>-53</u>
48 48
z = -1⁵/₄₈
x = 4(-1⁵/₄₈) + 4
x = -4⁵/₁₂ + 4
x = ⁵/₁₂
y = -5(⁵/₁₂) - 4(-1⁵/₄₈) - 5
y = -2¹/₂ + 4⁵/₁₂ - 5
y = 1¹¹/₁₂ - 5
y = -3¹/₂
(x, y, z) = (⁵/₁₂, -3¹/₂, -1⁵/₄₈)
1) 125mph
miles per minute
= 125/60
= 25/12
= 2.083 miles per minute
2) 10mph
miles per second
= 10/60/60
= 1/360 feet per second
3) 2 megabytes per second
= 2*60*60
= 7200 megabytes per hour
