9)To find the LCD you need to find a number that all of the denominator numbers can divide into, for this problem it would be 12. 12/6+12/4+12/3=1
2+3+4=1
9=1
No solution
10) In order to solve this problem you need to cross multiply
2(3x+5)=7(10
6x+10=70
6x=60
x=10
Have a great day!:)
Answer:
x = -3/4
Step-by-step explanation:
Simplify the equation.
5x - 3(3x + 7) = y
5x - 3*3x + 7 *(-3) = y {Distributive rule}
5x - 9x - 21 = y
Combine like terms
-4x - 21 = y
Now, substitute the value of y = -18
-4x - 21 = -18
Add 21 to both sides
-4x = -18 + 21
-4x = 3
Divide both sides by -4
x = -3/4
Answer:
Step-by-step explanation:
let be a constant written as:
It is given that y=4, x=-40
#We substitute x, y values in our function:
We substitute the constant value in the equation:
Answer:
8/-7
Step-by-step explanation:
using the equation: y₂-y₁/x₂-x₁
10-2/0-7 = 8/-7
Answer:
66 turned into 22 because the fraction was simplified.
Step-by-step explanation:
Both 66 and 9 can be divided by 3 to get 22 and 3 so
66/9 turns into
22/3
