To solve equations, all we must do is isolate the variable and simplify. In this case, we need to get rid of the "/7" because it i with our "e." To do this, we should do the reverse operation of "/7" on both sides, and them simplify.
-5=e/7
*7 *7
-35=e
Using the math above, we can see that e=-35.
Answer:
Expressions for y:
1. A - 3B
3. A/3 - B
3. (27/13, -60/13)
Step-by-step explanation:
Expressions for y:
A - 3B
A/3 - B
Find combinations to eliminate x
A) 8x + y = 12
B) 2x - 3y = 18
Expressions for y:
A - 3B
A/3 - B
y = 12 - 8x
2x - 3(12 - 8x) = 18
2x + 24x - 36 = 18
26x = 54
x = 54/26 = 27/13
y = 12 - 8(27/13) = -60/13
Answer:
B: f(x) = ( x + 1 ) 2 + 5
Step-by-step explanation:
I had this very same question on a quiz not so long ago. I'm good with numbers and math so I easily remembered the answer.
<em>*Haily</em>
I am going to answer what is 1/4 - 1/3 - 3/4.
To do this we need to convert this into a common denominator.
We have that:
1/4 = 3/12
1/3 = 4/12
3/4 = 9 / 12
So 3/12 - 4/12 - 9/12 = -10/12
The answer is -10/12.
