Answer:
3
Step-by-step explanation:
(20a - 1) ÷ b
a = 2
b = 13
(20(2) - 1) ÷ 13
(40-1)÷13
39÷ 13
= 3
Answer:
132
Step-by-step explanation:
From googling linear pair you we now that both angles add to 180.
2x + (2y - 10) = 180
You are missing out information since there are two unknowns, x and y. To solve two unknowns we need to equations. If you would like to comment what the other equation could be i.e. there could be another 'linear pair' rule that I don't know about - which is likely - I'd reply and solve it better for you.
Answer:
The initial Carla's balance was $96
The equation is x-7=89
Step-by-step explanation:
Let
x ----> initial Carla's balance
we know that
The linear equation that represent this problem is equal to
x-7=89
solve for x
Adds 7 both sides
x=89+7
x=$96
Answer:
a) x=3
b) x=4.5
Step-by-step explanation:
2(5x – 3) = 24
10x-6=24
10x=30
x=3
5(2x + 1) = 50
10x+5=50
10x=45
x=4.5
