Answer:
Step-by-step explanation:
Let E = Erasers and P = Pencils
4E + 2 P = $16…(1)
3E + 1P = $10.50…(2)
Multiply (2) by 2 to make Pencils in (1) and (2) equal.
6E + 2P = $21…(3)
Subtract (3) from (1) to eliminate P
2E = $5 => Erasers = $2.50 each
Substitute this value for Erasers into (3)
6 * $2.50 + 2P = $21
2P = $21 - $15 = $6 => Pencils = $3
Therefore 5 Erasers + 3 Pencils cost
5 * $2.50 + 3 * $3 = $12.50 + $9 = $21.50
Answer:
y=(-2/3)x-9
Step-by-step explanation:
1) first put the equation in terms of y. You should get y=-(2/3)x-8.
2) parallel lines have the same slope so the slope for this line and the answer should be the same
3) using the form y=mx+b plug (-2/3) in as the slope or m
4) plug the point in to get your b value. you should have -7 =((-2/3)•(-3))+b
5) isolate the variable b and plug in your answer to the equation.
100,000
Since 8 rounds up to 10, it will go up to 100,000.

Step-by-step explanation:
● A standard deck of cards has:
● 52 Cards in 13 values and 4 suits
● Suits are Spades, Clubs, Diamonds
and Hearts
● Each suit has 13 card values:
2-10, 3 “face cards” Jack, Queen, King (J, Q, K)
and and Ace (A)
Basic Card Probabilities
● If you draw a card at random, what is the
probability you get:
● A Spade? P(Spade)=13/52
● A Face card? P(Face Card)=12/52 (or simply 3/13)
● A Red Ace? P(Red Ace) = 2/52
