(7x-y=7
(x+2y=6 estimate the solution to the system of equations

Answers

Answer:

x=4/3; y=7/3

Step-by-step explanation:

x+2y=6,

x=6-2y.

7(6-2y)-y=7,

42-14y-y=7,

15y=35,

y=7/3.

x+2y=6,

x+2*7/3=6

x=4/3

∴x=4/3, y=7/3.

Final answer:

To estimate the solution to the system of equations (7x-y=7) and (x+2y=6), we can use the method of substitution. The estimated solution is x = 1.46 and y = 2.27.

Explanation:

To estimate the solution to the system of equations (7x-y=7) and (x+2y=6), we can use the method of substitution. We can solve one equation for one variable and substitute it into the other equation. Let's solve the second equation for x: x = 6 - 2y.

Substituting this value of x into the first equation, we get:

7(6 - 2y) - y = 7

42 - 14y - y = 7

41 - 15y = 7

-15y = 7 - 41

-15y = -34

y = -34 / -15

y = 2.27

Now, substitute this value of y back into the second equation to find x:

x + 2(2.27) = 6

x + 4.54 = 6

x = 6 - 4.54

x = 1.46

Therefore, the estimated solution to the system of equations is x = 1.46 and y = 2.27.

The meal costs $7.50. She wants to leave a 20% tip.

A 10% tip would be 75 cents ($0.75), because 7.5 / 10 = 0.75.

A 20% tip would be $1.50 because 7.5 / 5 = 1.50

You can also multiply the 10% answer by 2 to get the same number.

Donald bought a box of golf balls for $9.59. There were 18 golf balls in the box. About how much did each golf ball cost?

Answers

The price (9.59) divided by the number of golf balls (18).

9.59 (divided by) 18 = .53

One golf ball cost around $0.53 or 53 cents.

You can also check the work by multiplying 18 by 0.53 which is 9.59.

One pack costs $9.59, which contains 18 balls. To obtain the cost of each ball, you divide $9.59 by 18, which is about 53 cents
