Answer:
Original Price= $20
Sales Price= $20*0.80= $16
7.05 is the correct answer
Answer:
A) 7p+15
Step-by-step explanation:
To first start things off, we know she automatically has a fee of 15 dollars. No matter what, she must pay the 15 dollars!
Using this information, we know that so far we have: 15+
We also know that it costs 7 dollars for one pizza. If Mrs. Carter decides to buy more then just one pizza then how will we express it? We can express by writing 7x. The reason we have a x with the 7 is because x is the total amount of pizzas.\
Now we combine what we have.
15+7x= the total amount of dollars for x pizzas bought!
I hope this helps! :)
(Side Note: if she gets 2 pizzas you plug in 2 for x.)
Answer:
n = 4.5
Step-by-step explanation:
I think it is 4.5 because n is 3 units ahead of 1.5 on the number line:
1.5+3=4.5
Answer:
Step-by-step explanation:
b.
(0,2)
2y - x > 1
2(2) - 0 > 1
4 - 0 > 1
true, (0,2) is a solution to the inequality
(8,1/2)
2y - x > 1
2(1/2) - 8 > 1
1 - 8 > 1
-7 > 1
false, (8,1/2) is not a solution to the inequality
(-6,3)
2y - x > 1
2(3) - (-6) > 1
6 + 6 > 1
12 > 1
true, (0,2) is a solution to the inequality
(-7,-3)
2y - x > 1
2(-3) - (-7) > 1
-6 + 7 > 1
1 > 1
false, (8,1/2) is not a solution to the inequality
(1 is not greater than one, but equal. since the inequality is not "greater than or equal to", this equation is false)
c. the top half should be shaded
d. no, because the inequality is >, not >=. therefore, the points on the line are not included in the solution set.
