Answer:
$0.80 per notebook
$0.40 per pencil
Step-by-step explanation:
To find the rate, we need to determine how much each item costs. That is, the cost per item.
Given that,
4 notebooks = $3.20
The cost of 1 notebook/rate = 
Rate = $0.80 per notebook
Given that,
12 pencils = $4.80
The cost of 1 notebook/rate = 
Rate = $0.40 per pencil.
Answer:
Sophie has to work 18 hours to buy the sneakers.
Step-by-step explanation:
Since Sophie earns $ 12.80 per hour babysitting, and she has to repay a loan to her parents in the amount of $ 100, and after repaying the loan, she wants to have at least enough money to buy herself a pair of sneakers costing $ 130.40, for write an inequality modeling the number of hours, X, Sophie needs to work to have enough money to buy the sneakers, the following mathematical reasoning must be carried out:
12.80X = 100 + 130.40
12.80X = 230.4
X = 230.4 / 12.8
X = 18
So Sophie has to work 18 hours to buy the sneakers.
AB = 4/3
BC = -2/7
CD = 4/3
AD = -2/7
Parallelogram because both sides are parallel
Y+y+17+111+90=360
2y+128+90=360
2y=360-218
2y=142
y=142/2
y=71
thus, the angles are 71, 90, 111, 88.
