52+4y=12

We move all terms to the left:

52+4y-(12)=0

We add all the numbers together, and all the variables

4y+40=0

We move all terms containing y to the left, all other terms to the right

4y=-40

y=-40/4

y=-10

_______________________________________________________

3.1-3y=18

We move all terms to the left:

3.1-3y-(18)=0

We add all the numbers together, and all the variables

-3y-14.9=0

We move all terms containing y to the left, all other terms to the right

-3y=14.9

y=14.9/-3

y=-4+2.9/3

Ket [755]

Answer:

z = 32/3

Step-by-step explanation:

Presuming all the horizontal lines are parallel, the ratios of lengths will be identical.

3/8 = 4/z

3z = 8(4)

z = 32/3

How many triangles would be needed to cover 7/3 trapezoid 7/3 ×3=7 Am I right I think it 21 doe.
jarptica [38.1K]

Answer:

5 or 6 (or 2 or 7)

Step-by-step explanation:

Any quadrilateral can be covered by 2 triangles, so the integer number in 7/3 = 2 1/3 quadrilaerals will require 2×2 = 4 triangles.

The meaning of (1/3) trapezoid determines the number of additional triangles required. If 1/3 trapezoid is a triangle, only one is needed. If 1/3 trapezoid is a quadrilateral, then 2 triangles are needed.

_____

If the 7/3 trapezoids are butted against each other so they make a larger quadrilateral figure, then only 2 triangles are needed.

_____

If each trapezoid is constructed from 3 equilateral triangles, and you want to know the total number of those equilateral triangles in 7/3 such figures, it will be 3 × 7/3 = 7.

The answer depends on problem details not provided here.
