-1/2 + 2/3= Give simplified answer

1 answer:

6 0

You need a common denominator of 6 because it's the least common denominator of 2 and 3. So you can change -1/2 to -3/6. And change 2/3 to 4/6. The new equation would be -3/6 + 4/6 = 1/6.

Need help with 5. Part C

Mamont248 [21]

Answer:

BA = 12

Step-by-step explanation:

All the right triangles are similar, so the ratio of hypotenuse to long side is a constant. In particular ΔABC ~ ΔDBA, so ...

hypotenuse/long-side = BC/BA = BA/BD

Cross multiplying gives ...

BA² = BC·BD

BA = √(BC·BD) = √(16·9)

BA = 12

Y=6x - 11 -2x - 3y = -7

Ray Of Light [21]

<h2>Therefore x=2 and y= 1</h2>

Step-by-step explanation:

Given equations are

$y = 6x -11$ and $-2x -3y = -7$ .........(2)

⇒ $y - 6x = -11$ .......(1)

Equation (2)× 3 - Equation (1)

$-6x -9y -(y-6x) = -21 -(-11)$

⇔ $-6x -9y-y+6x=-21+11$

⇔-10y = -10

⇔y=1

Putting the value of y in equation (1) we get

$1 = 6x -11$

⇔x =2

Therefore x=2 and y= 1
