In XYZ, XY=XZ<br> Find the length of XY of XYZ if XY=2a, YZ=3a+1, andXZ=5a-12
lorasvet [3.4K]

Answer: XY = 8

Step-by-step explanation:

The diagram of the triangle XYZ is shown in the attached photo.

XY=XZ. This means that two sides of the triangle are equal. Two angles are also equal. It means that the triangle XYZ is an isosceles triangle.

Since XY=XZ, then

2a = 5a - 12

Subtracting 2a from both sides of the equation,

2a - 5a = 5a - 12 - 5a

-3a = -12

a = -12/-3

a = 4

Therefore, the length of XY is 2a = 2×4 = 8

Rom4ik [11]

Answer:

100 +3s≥ 160

You must sell as least 20 items

Step-by-step explanation:

You make 100 plus 3 dollars per sale

100 +3s

It must be at least 160

100 +3s≥ 160

Now we need to solve to see how many sales

100 +3s≥ 160

Subtract 100 from each side

100-100 +3s≥ 160-100

3s≥ 60

Divide each side by 3

3s/3≥60/3

s≥20

You must sell as least 20 items
