Answer:

-2

Step-by-step explanation:

We subtract 2 from the answer instead of adding it to 2v.

2v = -4

We can divide -4 by 2 instead of multiplying v by 2.

v = -2

What’s the value of x

Veseljchak [2.6K]

Answer:

(3x + 4)° + 50° = 90° (complement angle)

3x° + 4°+ 50° = 90°

3x° +54° = 90°

3x° = 90°- 54°

x° = 36°/3

x° = 12°

xenn [34]

Answer:

$\large \boxed{\text{23 s}}$

Step-by-step explanation:

Jaime is at point A and wants to get across the river to Point B.

They must head upstream towards Point C.

1. Calculate the net speed across the river.

∆ABC is a right triangle, so

$\begin{array}{rcl}AB^{2} + BC^{2} & = & AC^{2} \\AB^{2} +10^{2} & = & 12^{2} \\AB^{2}+100& = & 144 \\AB^{2}& = & 44\\AB & = & \sqrt{44}\\& = & 2\sqrt{11}\\& \approx &\textbf{6.633 m/s}\\\end{array}$

2. Calculate the time to cross the river

$\text{Time} = \text{150 m} \times \dfrac{\text{1 s}}{\text{6.633 m}} \approx \textbf{23 s}\\\\\text{It will take $\large \boxed{\textbf{23 s}}$ to cross the river.}$
