Alright, so 2x+2=0 (with x being the number) is what I'm getting from this. Subtract 2 from both sides to get 2x=-2, and then divide by 2 to get x=-1

2y - 3/5 = 1/2

Add 3/5 to both sides.

2y = 1/2 + 3/5

Let's make the two fractions have common denominators.
Multiply 1/2 by 5/5 and 3/5 by 2/2.
1/2 * 5/5 = 5/10
3/5 * 2/2 = 6/10

2y = 5/10 + 6/10

Add the two fractions.

2y = 11/10

Divide both sides by 2.

11/10 ÷ 2
Use the Keep, Change, Flip method.
Keep 11/10, change ÷ to ×, and flip the 2 (reciprocal).
11/10 × 1/2 = 11/20

y = 11/20

Write a vector equation of the line that passes through p(–1 6) and is parallel to a = (3, -1).

Phoenix [80]

Answer:

Step-by-step explanation:

(x,y) = p + t(a)

(x,y) = (-1,6) + t(3,-1)

(x,y) - (-1,6) = t(3,-1)

(x + 1, y - 6) = t(3, -1)

Juanita is cutting a piece of construction paper in the shape of a parallelogram. Two opposite sides of the parallelogram have l

Tema [17]

Answer:

4 cm and 7 cm

Step-by-step explanation:

Given that Juanita is cutting a piece of construction paper in the shape of a parallelogram. Two opposite sides of the parallelogram have lengths (5n − 6) cm and (3n − 2) cm.

We know that opposite sides are equal in a parallelogram.

Hence we have

$5n-6 = 3n-2\\2n =4\\n=2$

Hence the side length = $5(2)-6 =4 cm$

The adjacent side = $2n+3\\=2(2)+3\\=7cm$

Thus answer is 4 cm and 7 cm
