How do I solve these for example 3

Natasha2012 [34]

As the three longitudinal lines are parallel:

angle 4 = 5 = 6 = 82 degree (corresponding angles) = 9 = 8 = 7 = 82 degrees (vertical angles)

and

angle 11 = 180-82= 98 degrees (linear pair)

so:

angle 10 = 11 = 12 = 98 degrees (corresponding angles) = 3 = 2 = 1 = 98 degrees (vertical angles)
.

hope you got it

1. -28 = -3n + 5<br> what is n??<br> 2.5−n3=−4

STatiana [176]

Answer:

n=11

$n = \sqrt[3]{9}$

Step-by-step explanation:

Question 1:

The given equation is:

$- 28 = - 3n + 5$

Subtract 5 from both sides:

$- 28 - 5 = - 3n$

$- 33 = - 3n$

Divide boy sides by:

-3

$n = \frac{ - 33}{ - 3} = 11$

Question 2:

The given expresion is :

$5 - {n}^{3} = - 4$

Subtract 5 from both sides

$- {n}^{3}= - 4 - 5$

This implies that;

$- {n}^{3}= - 9$

${n}^{3}= 9$

$n = \sqrt[3]{9}$

When you add or subtract numbers over sings do you flip them?

Say you have this problem.

4x=2x-4

First you would combine your like terms.

4x = 2x-4
-2x=-2x-4
---------------
2x=-4

Next you would divide

2x =-4
÷ -4 =-4
--------------
x = 0.5
