J is correct. the scale is balanced, so x = 1. there are 9 1’s on the right, and 6 1’s on the left. there are 3 more blocks, and they would have to each be 1.

The length of each side of an equilateral triangle is increased by 5 inches, so the perimeter is now 60 inches. Write and solve
AfilCa [17]

Answer:

The original length of each side of the equilateral triangle = x =15 inches

Step-by-step explanation:

Let Original length of side of equilateral triangle = x

If it is increased by 5 inches, the length will become = x+5

Since in equilateral triangle all the ides have same length so,

New Length of side 1 = x+5

New of side 2 = x+5

New Length of side 3 = x+5

Perimeter of triangle = 60 inches

We need to find the value of x

The formula used is: Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3

Putting values in formula and finding x

Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3\\60=x+5+x+5+x+5\\60=3x+15\\60-15=3x\\45=3x\\x=\frac{45}{3}\\x=15

So, the original length of each side of the equilateral triangle = x =15 inches

Help!!!!!!!!!!!!!!!!!!!
Sphinxa [80]

Answer:

  • 1) y = (-2/3)x +2/3
  • 2) y = (6/5)x -23/5
  • 5) y = (-1/6)x +4/3
  • 6) y = x -2

Step-by-step explanation:

A simple, mechanical way to do these (perpendicular lines) is ...

  • replace any constant with 0
  • swap the x- and y-coefficients, negating one
  • for point (h, k), replace x with (x-h) and y with (y-k)
  • solve for y (to get slope-intercept form)

1) 3x -2y = 0 . . . . . step 1

... 2x +3y = 0 . . . . step 2

... 2(x -1) +3(y -0) = 0 . . . . step 3

... 2x -2 = -3y . . . . eliminate parentheses, subtract 3y

... y = (-2/3)x +2/3 . . . . divide by the coefficient of y

2) 6(x -3) -5(y +1) = 0 . . . . after step 3

... 6x -23 = 5y . . . . . . . . . . simplify, add 5y

... y = (6/5)x - 23/5 . . . . . divide by the coefficient of y

5) (x+4) +6(y-2) = 0 . . . . . after step 3

... x -8 = -6y . . . . . . . . . . . simplify, subtract 6y

... y = (-1/6)x +4/3 . . . . . . divide by the coefficient of y

6) (y +5) = (x +3) . . . . . . . after step 3

... y = x -2 . . . . . . . . . . . . subtract 5
