For homework, Fred has to read 30 minutes daily. It takes him 2 minutes per page, and he spends 4 minutes viewing graphics in the book. If x represents the number of pages he reads, then 2x + 4 ≥ 30 represents the time he reads each day. What is the fewest number of pages Fred must read to complete his homework?
i believe its 13
yea i thot so
they gave you the inequality here, 2 min/page*(#pages) + 4 min >= 30 minutes total
thx
i have another
ok
13
Which equation best represents the situation? Cara served pizza and punch at a party. Each pizza fed 6 people, and each guest received a glass of punch. If a glass of punch cost 50¢, and Cara spent $2.50 for each guest, what was the cost of each pizza?
solve for the range of x, the pages
ur too late dan lol
well they don't give you the inequality this time,,

tso the concept has to be put together
can someone help me with this problem

it says i gotta log in... the best way i can help you is by saying she only bought one pizza because she only had 5 guests
Each guest cost $2.50 total, that is the same cost as 1/6 of a pizza, and one glass of drink
put that into an equation 2.5 = p/6 + 0.5 balancing the $$
oh then the pizza would be twelve dollars?
a.x/6+.50=2.50 b.6x+.50x=2.50 c.x/6+50=2.50 d.6x-2.50=.50
1 guest cost 2.50 and consumed 1/6 a pizza and one drink 2.50 = x/6 + 0.5
so it would be a
yes,
oh yeah lol..
okay thx i have a couple more if you guys can help?
The main point is to read the thing a couple times, summarize it, and convert that to equation(s)
suuure
If you can keep track of units well, that makes it much easier
Which inequality best represents the situation? A pine tree grows at a rate of 1.5 feet per year. James plants a 2-foot tall pine tree in his yard. How many years will it take for the tree to be at least 14 feet tall?
okay dan
A. 2x + 1.5 ≥ 14 B. 2x – 1.5 ≤ 14 C. 1.5x + 2 ≥ 14 D. 1.5x – 2 ≤ 14
i think d
Here is my thought, 1)the tree grows at a constant rate, 1.5 ft / 1 yr, it must be a linear relationship
okay
so we divide
for each increase in yrs, the height grows the same amount, constant slope for a line
i think its c
says it starts at 2 ft tall, that is the value at time of zero, and the y intercept for the line
right so that means that we need to dive those 2 numbers
okay
they give you 1 point, and the slope, you can make an equation for a line
its c
y = m*x+b y = 1.5x + 2
hwo is that mega
oh so it is c y
exactly dans equation y = 1.5x + 2
ohhhhh right
okay
now that you know the equation for the line, y = 1.5*x + 2 they want to know when it will be at least 30 ft tall? the 1.5x + 2 has to be greater than or equal to 30 ft
is that it?
yes, that is how i would think thorugh it, basically
You want to find out how many cards were in Mona's deck at the beginning. Which situation about her game best represents the equation x/4+2=10 ?
Mona gave 4 players an equal number of game cards and then put 2 cards back in the box. After that, the first player had 10 cards. B. Mona gave 4 players an equal number of cards and then gave the first player 2 extra cards. After that, the first player had 10 cards. C. Mona gave 4 players an equal number of cards and then gave each player 2 additional cards. After that, each player had 10 cards. D. Mona gave 4 players an equal number of cards and then gave 1 more card to 2 players. After that, the first player had 10 cards.
I think b
no c
right?
from the question it is hard to tell, since there are no units for x and 10, cards vs players
so you have to read the responses, and figure that
hmmmm?
could u help me with that?
x is the number of cards in the full deck
okay
so we would subtract
without x
right?
come one mathlete
sorry, had to step away a second...
thats okay
the 4 is the number of players that was given, ...
right
the total cards x, was divided by the number of players, x/4
okay
so substract?
thif you look at the units there, you get cards per player cards / player the units have to be the same on both sides of the equation, so that constant 2, and 10 will also be cards/player
cards / player + cards / player = cards / player
so the answer is c right? or
sorry, i will restart, was distracted, and this is wrong.
what is ?
is is a ? do u know the answer?
talk to meh
hello?
hey umm? so i kinda dont have much time till i have to go so if you could just ya know help meh that would be awesome lol
so its c
right?
