Your next Pre-Algebra test is worth 93 points and contains 38 multiple choice and short answer problems. Each
multiple choice problem is worth two points and each short answer is worth three points. How many of each type of
problem is on the test?

Answers

Answer:

There are 21 multiple-choice problems and 17 short answers.

Step-by-step explanation:

Let there are x multiple-choice problems and y short answers.

ATQ,

x+y = 38 ....(1)

Each  a multiple-choice problem is worth two points and each short answer is worth three points.

2x+3y = 93 ....(2)

Multiply equation (1) by 2.

2x+2y = 76 ....(3)

Subtract equation (2) and (3) we get :

2x+3y-(2x+2y) = 93-76

2x+3y-2x-2y = 17

y=17

Put the value of y in equation (1).

x+17 = 38

x=21

Hence, there are 21 multiple-choice problems and 17 short answers

Melanie is buying soft drink cans for the work fridge. In the shopping catalogue, she sees a 10 can
pack for $6.00 and a 24 can pack for $15.96. Which is the cheapest way for Melanie to buy the soft
drink? Show all working

Answers

If you buy the 10-pack you pay 60 cents per can ($6.00 / 10 cans = .60/can). If you buy the 24-pack, you pay more than 66 cents per can ($15.96 / 24 cans = .665/can). So it is cheaper to buy the 10-pack (60 cents vs. 66 cents for each can)

Find the percent error in this situation:
Estimated value: 145
Actual value: 189

Answers

Answer:

30.3% im so sorry if this is wrong if it is u can report this :(

Step-by-step explanation:

Answer:

23.3%

Step-by-step explanation:

You have to first take the estimated value - the actual value

= 145-189 = -44

Then you want to take -44 divide the actual value which is 189

= -44 / 189= 0.232804233

Lastly, you want to take 0.232804233 and multiply it by 100

= 0.232804233 x 100= 23.28042328

Round that number to get

=23.3%

Solving by substitution- Day 1
solve the following system of equations y=9x-9 y=9

Answers

Answer:

(x, y) = (2, 9)

Step-by-step explanation:

y = 9x - 9

y = 9

Substituting the value of y ( second equation) into the first eqaution, we get:

9 = 9x - 9

18 = 9x

x = 2.

Answer:

(x, y) = (2, 9)

Step-by-step explanation:

y = 9x - 9

y = 9

Substituting the value of y ( second equation) into the first eqaution, we get:

9 = 9x - 9

18 = 9x

x = 2.

THE THREE SIDES OF A TRIANGULAR LOT
ARE MEASURED TO BE APPROXIMATELY 100.52
FT, 15.321 FT AND 143.250 FT LONG. FIND THE
APPROXIMATE PERIMETER OF THE LOT​

Answers

Answer:

259.09 feet

Step-by-step explanation:

Given that,

The three sides of a triangular lot are measured to be 100.52 ft, 15.321 ft and 143.250 ft.

We need to find the perimeter of the lot.

We know that,

Perimeter = sum of all sides

P = 100.52 + 15.321 + 143.250

P = 259.09 feet

So, the required perimeter of the lot is 259.09 feet.

Step-by-step explanation:

Q1.

y = -1/3x - 1x + 3y = -12

Solution

x + 3(-1/3x - 1) = -12x - x - 3 = -12-3 = -12

No solution

Q2

y = 2x - 4y = x + 1

Solution

2x - 4 = x + 1x = 5y = 6

(5, 6)

Q3

y = -3x + 36x + 2y = 6

Solution

6x + 2(-3x + 3) = 66x - 6x + 6 = 66 = 6

Infinitely many solutions

Q4

- 5x + y = 1- 10x + 2y = -2 ⇒ -5x + y = -1

Solution

1 = -1

No solution
