Hello :
in the arithemitic sequence : an = an-1 + 30
Answer:
infinitely many solutions
Step-by-step explanation:
x + 6y = -5
3x + 18y = -15
Multiply the first equation by 3
3(x + 6y) = -5*3
3x + 18y = -15
The two equations are identical. This means they have infinite solutions along the line x+6y = -5
Answer: 2600
Step-by-step explanation:
We want two digits that are not 0. These are the significant figures.
= 2600
Answer:
.....
Step-by-step explanation:
i think 1.6.
is it correct?
Answer:
z=116 (opposite angles are equal)
y=180-(116+27)=37(angles in a triangle sum up to 180)
x:
(z) + (27+x) =180(interior angles on same side are supplementary
116 + 27+ x =180
x= 37
