Answer:
If x = 3y and 3y = x, then y = 1/3x.
Answer:
x= (5±√29)÷2
Step-by-step explanation:
Quadratic formula:
x= (-b±√b²-4ac)÷2a
Answer: x=6
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
Step-by-step explanation:
We know that on both 10 & 12 the angles add up to equal 90° so...
10. 8x+7x=90
15x=90
x=6
12. it's the same in pic as 10
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
