Answer:

we can describe the parts of the expression that the arrows

point to 3x-2 such as:

↑(x variable)

$3x-2$ ← (2 constant)

↓

(3 coefficient)

Step-by-step explanation:

Given the expression

$3x-2$

As we have to describe the parts of the expression the arrows

point to $3x-2$ .

we can describe the parts of the expression that the arrows

point to 3x-2 such as:

↑(x variable)

$3x-2$ ← (2 constant)

↓

(3 coefficient)

Therefore, it is clear that:

The upper arrow '↑' points to the variable part 'x' of expression which is 'x'.

The lower arrow '↓' points to the coefficient part of the expression which is '3'.

The arrow '←' points to the constant part of the expression which is '2'.

Answer: $x=79^{\circ}\ and\ y=101^{\circ}$

Step-by-step explanation:

In the given picture, a parallelogram PQRS is given with angle 101°.

In a parallelogram opposite angles are equal.

Since, y is opposite to 101°.

Therefore y=101°

Also, the sum of the adjacent angles of a parallelogram is 180°

$\\\Rightarrow\ x+101^{\circ}=180^{\circ}\\\Rightarrow\ x=180^{\circ}-101^{\circ}\\\Rightarrow\ x=79^{\circ}$

A submarine cuts through the water at an elevation of 203 meters under the sea. The sub rises, and the elevation changes by 4.3

maw [93]

The answer is -76.1 meters.

The submarine elevation before rising is -203 meters (it is negative because it is under the sea level which has 0 elevation): d₁ = -203 m
After the first rising, it moved 64.5 m: l₁ = 4.3 · 15 = 64.5 m
After the second rising, it moved 62.4 m: l₂ = 5.2 · 12 = 62.4 m

So, to calculate the elevation of the submarine after rising (d₂), we will add (because it is not going deeper, it rises toward the elevation of 0) two movements to the elevation before rising:
d₂ = d₁ - (l₁ + l₂) = -203 + (64.5 + 62.4) = -203 + 126.9 = -203 + 126.9 = -76.1.
