Can anyone please help me with some math problems?

Answer 1

what is the math problem :)

Answer 2

heya... post the q here and we'll see what we can do?

Answer 3

ok thank you!
1. Choose the correct answer.

Yves bought 420 tropical fish for a museum display. He bought 6 times as many parrotfish as angelfish. How many of each type of fish did he buy?

Which is a system of equations to model the problem if x represents the number of angelfish Yves bought, and y represents the number of parrotfish he bought?
(Points : 1)
x + y = 6
y = 420x

x + 6y = 420
y = 6x

x ��������� y = 420
y = 6x

x + y = 420
y = 6x





Question 2. 2. Nancy has bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as angelfish. How many of each type of fish did she buy?
(Points : 1)
320 angelfish, 40 goldfish
160 angelfish, 200 goldfish
40 angelfish, 320 goldfish
20 angelfish, 160 goldfish





Question 3. 3. For each of the following questions, choose the correct answer.

Anita and Joelle bowl together and their combined total score for one game was 425 points. Anita���������s score was 40 less than twice Joelle���������s. What were their scores? Write a system of equations to model the problem if x represents Joelle���������s score, and y represents Anita���������s score.
(Points : 1)
x + y = 425
y = 2x ��������� 40

x + y = 425
y = 2x + 40

x ��������� y = 425
y = 2x ��������� 40

x + y = 40
y = 2x ��������� 425

Answer 4

k so i'm not going to do ur test for u, but happy to help u understand how to get the answer, k?

Answer 5

also... that copy paste didn't work so well...?
anyways: Q 1
u'd want to use "substitution" here when ur doing ur simultaneous equations
total number of fish = 420
6 times number of parrotfish (y) = number of angel fish (x)

Answer 6

so first equation is 6y = x

i think its better, I'm really behind and I need all the points i can get

Answer 8

total number of fish = x + y
so 2nd equation is
x + y = 420

Answer 10

dang it

Answer 11

so put the 2 together:
EQN 1: 6y = x
EQN 2: x + y = 420

... that's pretty much as far as you need to go to solve question 1. If you want to solve how many parrot fish (y) there are, you could sub equation 1 into equation 2 and solve for y... but u don't need to go that far. Follow so far?

Answer 12

I'm already lost.......

Answer 13

dammit ive got the x and y backwards anyway... sorry
6x = y... not 6y = x

Answer 14

Q1:
x = number of angelfish
y = number of parrotfish
there are 6 times the number of parrot fish in the tank
so 6x = y
total number of fish = number of angelfish + number of parrotfish
total number of fish = x + y
420 = x + y

so ur system of equations to solve are
6x = y
and
420 = x + y
...done for q1.

Answer 15

all i see is is x's and y's

Answer 16

ok... but wherever u see x: think ängelfish
and wherever you see y: read it as "parrotfish"
...does that help?

Answer 17

not at all......

Answer 18

Question 2. 2. Nancy has bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as angelfish. How many of each type of fish did she buy?
(Points : 1)
320 angelfish, 40 goldfish
160 angelfish, 200 goldfish
40 angelfish, 320 goldfish
20 angelfish, 160 goldfish

x = number of goldfish
y = number of angelfish
there are 8 times the number of goldfish in the tank
so x = 8y
total number of fish = number of angelfish + number of goldfish
total number of fish = y + x
360 = y + x

so ur system of equations to solve are:
360 = x + y
and x = 8y

Answer 19

i got that part

Answer 20

ok... well x and y are "variables"... they're used in a lot of calculus and algebra so maths people don't have to write words like "angelfish" or "boat 1" or "car a" in all of their equations... so u'll just have to remember with each equation what variable you assign to what real thing... in this case it's a type of fish for each variable... in other equations it may be 2 different cars in a race... or water flowing into a dam... or the number of crickets in a population, etc

Answer 21

um

Answer 22

Question 3. 3. For each of the following questions, choose the correct answer.

Anita and Joelle bowl together and their combined total score for one game was 425 points. Anitas score was 40 less than twice Joelles. What were their scores? Write a system of equations to model the problem if x represents Joelles score, and y represents Anitas score.

A = anitas score
J = Joelles score
their combined score was 425... so
A + J = 425

also anitas score was 40 less than twice joelles score... so
twice joelles score = 2J
40 less is 2J -40
so A = 2J - 40

those are ur 2 equations... u can use x and y or assign whatever variables you like, i just used A and J to keep it easy

Answer 23

ive had a enough..........

Answer 24

ok, sorry :(

Answer 25

just keep trying with them in ur own time tho, it will make sense eventually

Answer 26

not really
