Mingfa says, "My sister and I have $130 altogether. If my mother gives me another
quester [9]

Given:

Total amount of Mingfa and her sister = $130

If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.

To find:

How much money does Mingfa actually have?​

Solution:

Let, Mingfa have $x and her sister has $y initially. Then,

x+y=130                ...(i)

If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.

x+10=3y              ...(ii)

Substitute the value of x from (ii) in (i).

(3y-10)+y=130

4y=130+10

4y=140

Divide both sides by 4.

y=35

Putting y=35 in (i), we get

x+35=130

x=130-35

x=95

Therefore, Mingfa have $95.

PLEASE HELP DUE IN LESS THAN 5 WILL MARK BRAINLIEST!!!!!!!!!!
RUDIKE [14]

Answer:

1. 1:4

2. y = 4 x X

3. yes

Step-by-step explanation:

1. every 1 minuet he cleans 4 shrimp

2. y is the number of shrimp and x is the time. if every miuet he cleans 4 shrimp, then that means you have to multiply the shrimp by the minuets. for example, if he spends 2 minuets, he cleans 8 shrimp because 2 x 4 = 8.

3. This is a proportional relationship because if you were to put this on a graph, it would be a strait line. for example, if you were to plot x (the time) on a line (this line would go horizontal) and y (shrimp) on the line (this line goes verticle) 1 minuet = 4 shrimp. 2 minuets = 8 shrimp. 3 minuets = 12 shrimp. 4 minuets = 16 shrimp.

i hope this helps. tell me if this is too confusing or if you need more help. have a great day :)
