Step-by-step explanation:
Jessica made $16 mowing a neighbors yard
She brought a craft kit for $7.37
16-7.37
= 8.63
She used $3.75 to buy food for a food drive
8.63-3.75
= 4.88
Hence the amount Jessica put in the savings account is $4.88
Answer:
The three numbers are -1 6/7, -5 4/7, and 5 3/7
Step-by-step explanation:
The three numbers can be represented as...
x, 3x+11, and 3x
x+3x+3x+11=-2
7x+11=-2
7x=-13
x= - 1 6/7
3x= -5 4/7
3x+11= 5 3/7

The answer is below
Step-by-step explanation:
A) i)
For Anna initially, she has $0 from making 0 envelopes. After making 400 envelopes she has $20. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (400, 20). Using the equation of a line:
![y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{20-0}{400-0}(x-0)\\\\y=\frac{1}{20} x](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%28x-x_1%29%5C%5C%5C%5Cy-0%3D%5Cfrac%7B20-0%7D%7B400-0%7D%28x-0%29%5C%5C%5C%5Cy%3D%5Cfrac%7B1%7D%7B20%7D%20x)
The table is:
x: 200 400 600 800 1000
y: 10 20 30 40 50

For Jason initially, he has $0 from making 0 envelopes. For every 250 envelopes he has $10. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (250, 10). Using the equation of a line:
![y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{10-0}{250-0}(x-0)\\\\y=\frac{1}{25} x](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%28x-x_1%29%5C%5C%5C%5Cy-0%3D%5Cfrac%7B10-0%7D%7B250-0%7D%28x-0%29%5C%5C%5C%5Cy%3D%5Cfrac%7B1%7D%7B25%7D%20x)
The table is:
x: 200 400 600 800 1000
y: 8 16 24 32 40

Answer: the other side has to be five since they are the same which will equal to 10 so that means the other two sides should be 10 each
