Answer:
Yes
Step-by-step explanation:
If they're perpendicular, that means that angle ECM = 90 degrees and angle ACE = 90 degrees. To figure out if this works, plug that into the two equations they give:
ECM = 3x + 15
becomes
90 = 3x + 15
75 = 3x
25 = x
ACE = 4x - 10
becomes
90 = 4x - 10
100 = 4x
25 = x
Since you get x = 25 for both, you know that they are perpendicular because they both measure 90 degrees
First things first, you will have 94 + x. Place those on top of a fraction bar and on the bottom put the two numbers over 2. So you have 94 + x over 2. Then, write the symbol ‘greater than or equal to’ and on the other side place your 90. So, 90 + x over 2 is greater than or equal to 90. This is a difficult thing to write out and explain so I hope this makes sense. :)
3.5 miles / 1.25 hours = 2.8 mph
Answer:
let’s make a Unit rate.
$20/4 hours = $5 per hour
So you earn $5 in 1 hour if you earn $20 in 4 hours.
hope this helps and pls mark me brainliest if it did ;)
Answer:
13(4x-13)
if you distribute it then you come back with 52x-169.
