Answer:

y=15

x =40

Step-by-step explanation:

3x + 4y=180

and

(x+y+5)=4y

x+y+5=4y

x+5=4y-y

x+5=3y

<u>x=3y-5</u>

<u></u>

3x + 4y=180

3(3y-5) + 4y=180

9y-15 + 4y=180

9y+ 4y -15 =180

13y -15 =180

13y =180+15

13y =195

y =195÷13

y=15

3x + 4y=180

3x + 4(15)=180

3x + 60=180

3x =180 - 60

3x =120

x =120÷3

x =40

Answer:

583

Step-by-step explanation:

The mean of a data set is the average of the data set. It can be found by adding up all of the values and then dividing by the total number of values added. In this case, one is given the mean, and one needs to find a missing value. Since there is a missing element, add one to the total number of values in the data set. The missing element is represented by the parameter (x). Set up an equation and solve:

\frac{(236)+(342)+(328)+(352)+(352)+(306)+(317)+(x)}{8}=325\\

Simplify,

\frac{2233+x}{8}=352

Inverse operations,

2233+x=2816\\\\x = 583

Fergus has 3 1/4 cups of oats

= 13/4 cups of oats

Oatmeal bars = 2 2/3

= 8/3 cups of oatmeal used

Therefore cups of oats left = 13/4 - 8/3

= 39/12 - 32/12

= 7/12 cups of oats left

She borrowed 1 cup of oats from neighbour

7/12 + 1/1

= 7/12 + 12/12

= 19/12 cups of oats

Blueberry oats muffin = 1 3/4 cups of oats

= 7/4 cups of oats

Total she will have now = 19/12-7/4

= 19/12 - 21/12

= - 2/12

= -1/6

Which means she needs 1/6 cup of oats more

Therefore its option 4
