Let us say that the number of weeks is "x" and the number of chores is "y".
If we state an algebraic expression for Janie's allowance it would be
3x+2y=13
However, there are two variables, hence many answers. To solve this problem, there must be more information about the relation between x and y.
I’ll answer your question just help me with mine pls7:7
Answer:
-9y-2(2-7y)+4 expand the brackets using-2
Step-by-step explanation:
-9y-4+14y+4
arrange the like terms
-9y+14y-4+4
=5y becoz -4+4=0
ans=5y
x = 58°
<u>Explanation:</u>
According to the diagram, lines HI and JK are parallel to each other.
∠AHI = 60°
∠JKI = 62°
∠JKI and ∠HIA are equal because when two lines are parallel then the corresponding angles are equal.
So,
∠JKI = ∠HIA = 62°
In ΔHIA,
∠AHI + ∠HIA + ∠IAH = 180°
60° + 62°+ x = 180°
122° + x = 180°
x = 180° - 122°
x = 58°
