Solve for w k=2b-5w/3k
Answers
Answer:
b =
Step-by-step explanation:
To solve for w in this equation;
k =
This implies we have to make w the subject of the formula.
To make w subject of the formula, first we cross multiply.
3k × k = 2b - 5w
3k² = 2b -5w
Now we will subtract 2b from both- side of the equation
3k² - 2b = -5w
we want to make the right hand side of the equation positive, to do that , we will just multiply through by minus sign. The equation becomes;
-3k² + 2b = 5w
We can rearrange the equation;
2b - 3k² = 5w
5w = 2b - 3k²
Then we will now divide both-side of the equation by 5
In the left side of the equation, the 5 at the numerator will cancel out the 5 at the denominator.
Hence;
w =

Answers
Final answer:
To solve the given pair of linear equations y = -x + 5 and y = 2x - 7, you can use the elimination method. Multiply the second equation by -1, add the equations together to eliminate y, solve for x, and substitute the value of x back into either equation to find y. The solution is x = 4 and y = 1.
Explanation:
To solve the given pair of linear equations:
y = -x + 5
y = 2x - 7
You can use the method of substitution or elimination. Let's use the elimination method:
Step 1: Multiply the second equation by -1 to make the coefficient of y in both equations the same:
y = -x + 5
-y = -2x + 7
Step 2: Add the equations together to eliminate y:
0 = -3x + 12
Step 3: Solve for x:
3x = 12
x = 4
Step 4: Substitute the value of x back into either equation to find y:
y = -4 + 5
y = 1
So, the solution to the given pair of linear equations is x = 4 and y = 1.

Solve the given pair of linear equation in two variable.
y = -x + 5
y = 2x - 7
Answer: x=4, y=1
Step-by-step explanation:
Because y=y, you can make an equation that is -x+5=2x-7. Then add the x to the right side, so it would be 5=3x-7. Then add the 7 to the left side to get all of the numbers in one place. So it would be 12=3x. Divide by 3 on both sides and you get x=4. Then plug x into either one of the original equations. Both equations should get you the same answer for y. Y=-4+5. Y=1. And the other equation. Y=2x-7, y=8-7. Y=1

Answer:
A. and C.
right triangles have a right angle and scalene triangles don't have any congruent sides.
Isosceles means two sides are congruent.
Acute means all sides are 89 degrees or less.
