Given
<2 = 110°
• <2 = <4 so <4 = 110°
Step-by-step explanation:
Solution
• <4 is equal with it's front facing angle(the angle next to <1) let's call that angle <x
<4 = <x = 110°
<x + <1 = 180°
110° + <1 = 180°
<1 = 180° - 110°
<1 = 70°
• <4 + <3 = 180°
110° + <3 = 180°
<3 = 180° - 110°
<3 = 70°

Solve 5x + 2 = 22
Solve 2x-5=7
Solve 2x+5=12
Answers
Answer:
x = 4
x = 6
x = 7/2
Step-by-step explanation:
Solve 5x + 2 = 22:
5x+2-2=22-2 (subtract 2 from both sides)
5x=20
x=4
Solve 2x-5=7
2x-5+5=7+5 (add 5 to both sides)
2x=12
x=6
Solve 2x+5=12
2x+5-5=12-5 (subtract 5 from both sides)
2x=7
x= 7/2
=> 5x + 2 = 22
=> 5x = 22 – 2
=> 5x = 20
=> x = 20/5
=> x = 4
Solve 2x-5=7=> 2x - 5 = 7
=> 2x = 7+5
=> 2x = 12
=> x = 12/2
=> x = 6
Solve 2x+5=12=> 2x + 5 = 12
=> 2x = 12-5
=> 2x = 7
=> x = 7/2

The GCF of two numbers is 3 and the LCM is 180. If the one of the number is 45, what is the other number?
Answers
Answer:
45
Step-by-step explanation:
45 = 3*3*5
180 = 2*2*3*3*5 <---- so the other number had to contain a factor of 2*2 or 4
also, let the other number has to be of the form 3k and it must contain a factor of 4, how about 12 ?
check: lcf of 12 and 45 is 3,
the lcm of 12 and 45 is ...
12 = 2*2*3
45 = 3*3*5
so we need: 2*2*3*3*5 = 180

Slope = -4
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes, which means that multiplying their slopes result in a product of -1. Given the equation, x - 4y = - 12:
Transform the equation into its slope-intercept form, y = mx + b:
x - 4y = - 12
x - x - 4y = - x - 12
-4y = -x - 12
Divide both sides by -4:
[tex]\frac{-4y}{-4} = \frac{-x - 12}{-4}[/tex]
y = ¼x + 3 ⇒ (This is the slope-intercept form of the given standard equation, x - 4y = - 12).
Since the slope of the given equation is ¼, then it means that its negative reciprocal must be - 4:
(¼) (-4) = -1
Therefore, the slope of the line perpendicular to x - 4y = - 12 is - 4.

10. If you can travel 97 miles in 30 minutes, how many mileScan you
travel at the same rate in 8 hours?
Answers
Explanation: you want to set up a proportion
Ex:
97 X
—- x —
30. 480
The way I got 480 was I converted 8 hours into minutes because you want the same value of measurement.
After this, just cross multiply and you get the equation
46560 = 30mile
Then just isolate the miles (because you are trying to solve for 1 mile
Miles = 1,552
30 minutes is half of an hour so first you need to multiple 8•2 then you multiple 97 by what 8•2 is (16) that gets you 1552
