Answer:
y = 1/2 x -14.5
Step-by-step explanation:
2x-4y=58
solve for y
subtract 2x from each side
2x-2x-4y = -2x+58
-4y = -2x+58
divide by -4 on both sides
-4y/-4 = -2x/-4 +58/-4
y = 1/2 x -14.5
Answer:
y=2x-1
Step-by-step explanation:
y= 6x-1-4x
y=2x-1
The ratio of the side measures are 6:7:9.
Let's assume length of three sides of the triangle is 6x, 7x and 9x.
Given,perimeter of a triangle is 110 inches.. Perimeter is the sum of all three sides of the triangle. So, we can set up an equation as follows:
6x+7x+9x= 110
22x =110
Dividing each sides by 22.
x=5.
Now we can plug in x=5 in all the expressions of sides.
So, 6x=6(5)=30,
7x=7(5)=35
9x=9(5)=45.
So, the sides of the triangle are 30 inches, 35 inches and 45 inches.
