Both sides of the equation are not equal, therefore, Massa was wrong.

<h3>How to Evaluate an Equation?</h3>

For an equation to be correct, the values on both sides of the equation must be equal and balance.

Given the expression, 540 ÷ 6 = 9, 540 divided by 6 is 90. 90 is not equal to 9.

Thus, the value on the both sides are not balanced, therefore, Massa is incorrect.

ou live in the building on the left in the drawing, and a friend lives in the other building. the two of you are having a discus
Alenkinab [10]

Answer:

1.3

Friend is wrong

Step-by-step explanation:

Given:

friend's claim: height of his building is more than 1.50 times the height of yours

line of sight to the top edge of the other building makes an angle of 21° above the horizontal

line of sight to the base of the other building makes an angle of 52° below the horizontal

Solution:

Let A be the height of your building is A

Let B+A his building is B higher than yours.

Let the distance between the buildings is x.  

then

tan 52 = A/x

tan 21 = B/x  

A/B = tan 52 / tan 21

      =  1.27994 / 0.38386

A/B = 3.33

(A + B) / A = 1.5 0

A/A + B/A = 1.50

1 + B/A = 1.50

B/A is basically (B/x) / (A/x)

So

1+ 3.33 / 3.33

= 4.33/3.33

= 1.3

Since 1.3 is not equal to 1.5

Hence the friend's claim is wrong.

Which equations are equivalent to Y=2/3X-4 when written in slope-intercept form? Check all that apply. A =3X-2Y=4. B=2X-3Y=12. C
shusha [124]

The slope-intercept form: y = mx + b.

The standard form: Ax + By = C.

We have:

y=\dfrac{2}{3}x-4       <em>multiply both sides by 3</em>

3y=2x-12     <em>subtract 2x from both sides</em>

-2x+3y=-12       <em>change the signs</em>

2x-3y=12\to\boxed{B.}      <em>multiply both sides by (-4)</em>

-4(2x-3y)=-4(12)\to\boxed{C.}

<h3>Answer: B and C.</h3>

A. 3x - 2y = 4   - NOT

D. 2(x + 6) = 3y → 2x + 12 = 3y → 2x - 3y = -12      - NOT

E. 2x - 3y = 4    - NOT

Without dividing or listing multiples, how can you tell if 61 is a multiple of 6?
Slav-nsk [51]
You check if it is even and that the sum of the digits is divisible by 3. That's the divisibility rule of 6.
