To solve this problem, we must get the variable x alone on one side of the equation. To do this, first we must subtract 8 from both sides of the equation.
11=x/-5 + 8 = 19 = x/-5
Next, we must multiply both sides by -5, to cancel out the fraction term on the right side of the equation.
3 = x/-5 = -15=x
Therefore, x = -15, which is the solution to this equation.
Hope this helps!
Step-by-step explanation:
let v is the speed of the wind,
the equation of the speed:
(550 + v ) × 5 = (550 - v) × 6
2750 +5v = 3300 - 6v
11v = 3300 - 2750
11v = 550
v = 550/11
v = 50
therefore, the speed of the wind =
50 mph
Answer:x = - 5
y = 2
Step-by-step explanation:
The given system of simultaneous equations is expressed as
x + 3y = 1 - - - - - - - - - - - - - -1
4x + 4y = -12 - - - - - - - - - - - 2
We want to eliminate x. Multiplying equation 1 by 4 and equation 2 by 1, it becomes
4x + 12y = 4
4x + 4y = - 12
Subtracting the second equation from the first equation, it becomes
8y = 16
y = 16/8 = 2
Substituting y = 2 into equation 1, it becomes
x + 3 × 2 = 1
x + 6 = 1
x = 1 - 6 = - 5
I think the answer would be 112cm.
To find the area of the triangle you need to do basexheight divided by 2.
8x10 divided by 2 = 40
To find the area of the rectangle
12x6=72
40+72= 112cm
I’m not sure if it’s right but I hope this helps.
To get the denominator you would have to multiply w+5 by w-4
And whatever you do to the denominator you have to do to the numerator
(w-3)(w-4)
w^2-3w-4w+12
w^2-7w+12
So your answer would be c
