Nitella [24]

Answer:

$\frac{7.90 \times {10}^{ - 2} }{1.0 \times {10}^{ - 5} } \\ = 7.9 \times {10}^{5 - 2} \\ = 7.9 \times {10}^{3}$

How do you know when there are no solutions to a system of equations?

Allushta [10]

No solution
========
The lines are parallel
eg
y = 2x + 3; y = 2x + 5

Infinite solutions
============
When one equation reduces to the second one.
2y = 10x + 6
y = 5x + 3 When you divide the first one by 2, you get the second one.

Can someone explain how to do this?

Deffense [45]

So in a kite the total angles will add up to be 360°
Angles F and H are congruent (they are the same angle) so they will be the same number of °.
The formula we can use to find F and H is:
87+31+2x=360
(F and H are represented by 2x because they are the same angle twice).

Solving formula:

87+31+2x=360
118+2x=360
2x=360-118
2x=242
2x/2=242/2
x=121

So now we know both angle F and H equal 121° Hope this help! Comment if you have anymore questions

$-\frac{1}{3}m+2 = -1 =>NO\\-2(-4m-6.4) = 44.8 => YES\\8m-5-2m +1 = 20 =>YES\\7m+6 = 9m-2 => YES$

Step-by-step explanation:

First of all, we will find the solution of the given equation

So,

Given equation is:

$3m = 36-6m$

Adding 6m on both sides

$3m+6m = 36-6m+6m\\9m = 36$

Dividing both sides by 9

$\frac{9m}{9} = \frac{36}{9}\\m = 4$

In order to check, if the solution is the solution of given options, we will put the solution in the equation, if both sides of equations are equal then the solution belongs to the equation.

So,

For $-\frac{1}{3}m+2 = -1$
