Solved the inequality incorrectly but graphed their solution correctly.
Solved the inequality correctly and graphed their solution correctly.
Answer:
solved the solution incorrectly and graphic their solution correctly.
Step-by-step explanation:
this is because if 4x + 1<= -4
the next step will be to subtract 1 from both sides.
BUT if their solution is x<= 2, they objectively graphed it correctly
Step-by-step explanation:
4x+1 < -4
-1 -1
--------------
4x < -5
[tex]x \leqslant \frac{ - 5}{4} [/tex]
-5/4 is not 2, so both of them are wrong (1 is right choice)

Dean High School is taking a group of students on a cruise to Puerto Rico. The total number of tickets that were purchased is 90. There needs to be a ratio of 5:1 students to adults. Please answer the 3 questions
How many Students are going?
How many Adults are going?
There are other schools from Holyoke going on the cruise too. If the cruise ship holds a maximum of 400 passengers and each school gets the same number of tickets, how many schools can come on the cruise?
Answer:
75 students are going. 15 adults are going.
Step-by-step explanation:
Since the question says there are 90 tickets in total, 75 student ticket plus 15 adult tickets equals 90 tickets in total. Also 75 divided by 15 is 5, which suits the ratio of 5 students to per adult.
There wasn't enough information for me to solve the last one, but I hope this helps!

The sophmore class at south high school raised $800 from ticket sales for the dance. Tickets sold for $1.50 pre - sale, and $2.00 at the door. If a total of 475 tickets were sold how many tickets were sold at the door?
Answer:
So they sold 300 tickets in advance and 175 tickets at the door.
Step-by-step explanation:
Answer:
175 tickets were sold at the door.
Step-by-step explanation:
Let x = number of pre-sale tickets.
Let y = number of tickets sold at the door.
Equation for total number of tickets:
x + y = 475
Equation of total price of tickets:
1.5x + 2y = 800
System of equations:
x + y = 475
1.5x + 2y = 800
Solve the first equation for x:
x = 475 - y
Substitute into second equation.
1.5(475 - y) + 2y = 800
712.5 - 1.5y + 2y = 800
0.5y = 87.5
y = 175
Answer: 175 tickets were sold at the door.
Pls answer all four. Please and thank you & Thank you.

A) X ≥ 100
B) X ≥ -100
C) X ≤ 100
D) X ≤ -100
Answer:
c

the greater than sign turns into a less than sign when you cross multiply a negative number
and -4 times -25 is +100
whoever said b is braindead
Answer:
A) x ≥ 100
Step-by-step explanation:
x/-4 ≥ -25
x-4 x-4 (Multiply by -4 on both sides)
x ≥ 100
