At a restaurant, you eat 2 taco salads and drink two glasses of ice tea. Your friend eats 1 taco salad and drinks 1 glass of ice tea. The restaurant charges you $11 and your friend $6.50. Can you determine the prices of taco salads and ice tea? Explain.

Answers

Answer 1

Answer: Set up a system of equations that represent x as taco salads and y as iced tea:
2x + 2y = 11 (you)
x + y = 6.50 (your friend)
Solve the system of equations by solving one of the equations for a variable:
x+y = 6.50 (I solved for y):
y = 6.50 - x.
Plug this equation into the y of the first equation:
2x + 2(6.50 - x) = 11
Solve for x:
2x + 13 - 2x = 11
2x cancels out:
13 = 11
No solution, so it is not possible to determine the prices of the items.

Charlie saves 21.45 each month for 6 months in the seventh month he only saves 10.60 how much money will Charlie have saved in 7 months

Answers

If you would like to know how much money will Charlie have in 7 months, you can calculate this using the following steps:

21.45 each month for 6 months: 21.45 * 6 = 128.7
in the seventh month: 10.60

in 7 months: 128.7 + 10.6 = 139.3

The correct result would be 139.3.

A ten-foot-long board is cut into three pieces. The second piece is half as long as the first. The third piece is 4 feet longer than the second. How long is the first piece?

Answers

Let's say the second piece is x ft long
The first piece is 2x ft long
The third piece is x+4 ft long
All of the pieces should add up to 10ft
x+2x+x+4=10
4x= 6
x=1.5ft
The first piece is 2x ft long=3 ft long

you pay 3.3 cents per minute for long-distance phone calls on your phone. your phone bill is $3.40 write and solve an equation to find the number of minutes m of long-distance calls you made

Answers

If you would like to know the number of minutes of long-distance calls you made, you can calculate this using the following steps:

3.3 cents = $0.033
m = $3.40 / 3.3 cents
m = $3.40 / $0.033 = 3.40 / 0.033
m = 103.03 minutes

The correct result would be 103.03 minutes.

Two equations are given below:a – 3b = 16
a = b – 2

What is the solution to the set of equations in the form (a, b)? (5 points)

(–2, –6)
(–7, –9)
(–11, –9)
(–12, –10)

Answers

Asking the Math Gods...

a=-11
b=-9

Since a = b - 2, we can substitute this value into the other equation to find the value of b. Once we have a value for b, we substitute it back into one of the equations to find the value for a.

a - 3b = 16
b - 2 - 3b = 16
-2 - 2b = 16
-2b = 18
b = -9

Now substitute back into the equation

a = b - 2
a = -9 - 2
a = -11

Solution set in the form (a, b) is...

(-11, -9)
