Answer:

I don’t know about the last part but what I do know id the answer to the equation.

Answer: 1 1/3

Step-by-step explanation:

1. Remove the paranthesis

Removing the paranthesis will make it much easier to solve the equation.

We now have 4 1/6 + -2 5/6.

2. Rearrange the equation

We can’t have two symbols next to each other. We need to cross out one symbol so we can have only one. + and - = -. So let’s keep the "-" symbol.

We now have 4 1/6 - 2 5/6.

3. Solve the remaining equation

Now that we have a proper equation which we can solve, let’s do it.

We should then end up with 1 1/3.

Answer: 1 1/3

Alona [7]

Answer:

$R=883.74N$

Step-by-step explanation:

From the question we are told that:

Force 1 $F_1=226N$

Force 2 $F_2=331N$

Force 3 $F_3=377N$

Direction 1 $\theta_1=145 degrees \approx 35 \textdegree (2nd qudrant)$

Direction 2 $\theta_2=303 degrees \approx 57 \textdegree (3rd qudrant)$

Direction 3 $\theta_3=77 degrees$

Generally Resolving forces to X axis is mathematically given by

$\sum f_x=337cos77+331cos57+226sin35$

$\sum f_x=351.596N$

Generally Resolving forces to Y axis is mathematically given by

$\sum f_y=337sin77+331sin57+226cos35$

$\sum f_x=810.788N$

Generally the equation for Resultant force R is mathematically given by

$R=\sqrt{\sum f_x^2+\sum f_x^2}$

$R=\sqrt{351.596^2+810.788^2}$

$R=883.74N$

PLease help me out with this...I will mark the first one as the brainiest answer.

You cannot add row 2 to column 3 because they have different dimensions. You can do any of the other operations, but the only one that makes any sort of sense is ...
Multiply row 2 by -1 and add it to row 3

_____
It makes no sense to multiply a row by zero. That makes the entire row zero and makes the matrix useless for finding any sort of solution.

You can switch columns, but that doesn't get you any closer to a solution here.

If I were trying to find a solution, I might
switch rows 1 and 2
multiply the new row 1 by -3 and add it to the new row 2
multiply the new row 1 by 2 and add it to row 3
This sequence of operations will make the first column [1 0 0], reducing the problem to 2×2 from 3×3.

3/4log7(625)+2log7(x)=2 solve for x

sdas [7]

Simplifies to:
1.690196x+396.139706=2

Let's solve your equation step-by-step.
1.690196x+396.139706=2

Step 1: Subtract 396.139706 from both sides.

1.690196x+396.139706-396.139706=2-396.139706

1.690196x=-394.139706

Step 2: Divide both sides by 1.690196.
1.690196x/1.690196 -394.139706/1.690196

x= -233.191716
Answer: x= -233.191716
