Answer:
c = -2.4 or -12/5
Step-by-step explanation:
5c - 3 = -15
First we need to add 3 to both sides so,
5c - 3 + 3 = -15 + 3
so we can now solve it
5c = -12 then we divide 5 by both sides
c = -12 / 5
c = -2.4
The fraction form is -12/5
The decimal form is -2.4
Hope this helps!!
Answer:
14 and 10
Step-by-step explanation:
We have the equation x(x-4)=140. We can distribute the x to everything in the parenthesis so it's easier to work with.
x(x-4)=140
Let's move 140 to the left side, so we can solve this equation better by finding the zeros of the equation.
To find the zero, we have to find TWO values that multiply to -140 but add to -4.
(x-14)(x-10)=0
To find the zeros. make both of those parenthesis equal to zero.
x=14, 10
