Answer : 4 & 5
Explanation :
4x-5/8 >-10 + 3x |multiply by 8
4x-5> -80 + 24x. | minus 4x , add 80
-5+80 > 24x -4x
75> 20x. |divide by 20
3.75 > x
So x is greater than 3.75 therefore 4 and 5 are the answers
Alright, let's solve the second one because why not:
Let's then work on getting x by itself:
And that's your answer!
It's called a perpendicular line
The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.
To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.
Answer:
B) 34°
Step-by-step explanation:
149 - 115 = 34°
Exterior angle = sum of other interior angles
