Answer:
x = 7
Step-by-step explanation:
Because this is a right triangle, one angle is a right angle (90°). All triangles have all three angle measures adding up to 180°, so the other two angles' measures add up to 90° (90 + 90 = 180).
Combine like terms of the angle measures.
6x + 9x = 15x
-3 + (-12) = -15
15x - 15
Because the sum of the measures of the two angles have to equal 90,
15x - 15 = 90
Add 15 from both sides.
15x = 105
Divide both sides by 15.
x = 7
To check, substitute 7 in both expressions.
6(7) - 3 = 39
9(7) - 12 = 51
39 + 51 + 90 (the measure of the right angle) = 180, so the value of x is 7.
I hope this helped :)
The answer is 36. because 12x3=36, 9x4=36, and 4x9=36, so it is the least common denominator
Answer:
180miles=6gallons
1260miles=?gallons
1260/180*6
=42 gallons
Step-by-step explanation:
The answer is 28. My answer is correct. 7, 14& 21 can't be the LCM son the answer should be 28.
Hi There! :)
