Answer:

Y x 3 - 3 = Y + 57

30 would be your answer

add 3 to both sides so it becomes Y x 3 = Y + 60 and 60/2=30

30 x 3 = 90-3=87

30 + 57 = 87

Hope this helps (I am twelve and I know how to do this)

Rudi bought 12.5 yards of fabric to make pillows. Each pillow requires 1.75 yards of fabric. Use compatible numbers to estimate

Ipatiy [6.2K]

Hi there!

Using compatible numbers it would be:

12 ÷ 2 = 6.

Now when you divide it, the answer would be close to 6.

So, 12 ÷ 2 = 6 would be using compatible numbers.

Hope this helps ;)

Answer:

D. Reflection across x-axis

Step-by-step explanation:

When plotting the two points & then connecting the dots, it will not touch y-axis at all - it will be straight line and cross x axis

Tan inverse X + tan inverse Y + tan inverse z=pie prove that X+Y+Z=xyz<br>

vfiekz [6]

Answer:

see explanation

Step-by-step explanation:

Given

$tan^{-1}$ x + $tan^{-1}$ y + $tan^{-1}$ z = π

let

$tan^{-1}$ x = A , $tan^{-1}$ y = B , $tan^{-1}$ z = C , so

x = tanA, y = tanB , z = tanC

Substituting values

A + B + C = π ( subtract C from both sides )

A + B = π - C ( take tan of both sides )

tan(A + B) = tan(π - C) = - tanC ( expand left side using addition identity for tan )

$\frac{tanA+tanB}{1-tanAtanB}$ = - tanC ( multiply both sides by 1 - tanAtanB )

tanA + tanB = - tanC( 1 - tanAtanB) ← distribute

tanA+ tanB = - tanC + tanAtanBtanC ( add tanC to both sides )

tanA + tanB + tanC = tanAtanBtanC , that is

x + y + z = xyz
