10. The test was worth 100 points. There were 28 problems on the test. Some of the
problems were worth 3 points and others were worth 5 points. How many of each were
there?
Answers
Answer:
There are 20 3-point questions and 8 5-point questions
Step-by-step explanation:
x=3 point y=5 point
x+y=28 ----> x=28-y
3x+5y=100
3(28-y)+5y=100
84-3y+5y=100
84+2y=100
2y=16
y=8
28-8=20
Answer:
20 3-point questions and
8 5-point questions.
Step-by-step explanation:
Let there be x 3 point problems and y 5 point problems. So we have:
x + y = 28 Multiply this equation by -3:
-3x - 3y = -84
3x + 5y = 100 Adding the last 2 equations:
0 + 2y = 16
y = 8
So x = 28 - 8 = 20.

Hadley was going out with her friends for dinner. The equation c = x + 0.07x + 0.18x gives the total cost c of her meal, where x is the cost before tax and tip. The restaurant charges 7% sales tax and she plans to leave an 18% tip. She knew that she can only spend $18. What is the maximum amount Hadley can spend before tax and tip?
Answers
Answer:
$14.4
Step-by-step
c = x + 0.07x + 0.18x
18 = x + 0.07x + 0.18x
18 = 1.25x (simplify)
14.4 = x (divide both sides by 1.25)

Aden gets paid daily for the work she does and she does not work on Sundays. Last year which was n ot a leap year had 52 Sundays. She got Dhs 354003 as her annual salary last year. If the March of last year had 5 Sundays, how much did she earn in that month?
Answers
Answer: Dhs 29312.4
Step-by-step explanation:
For a leap year, we should note that there are 366 days. Since there were 52 Sundays, the number of days worked by Aden will be:
= 366 - 52
= 314 days
Since she got Dhs 354003 as her annual salary last year, the amount received per day will be:
= 354003 / 314
= Dhs 1127.4
The amount earned in March will be:
= (31 - 5) × 1127.4
= 26 × 1127.4
= Dhs 29312.4

Answers
Answer/Step-by-step explanation:
Area of trapezium = ½*(AD + BC)*AB
Area = 42 cm²
AD = (x + 8) cm
BC = (x + 5) cm
AB = x cm
Plug in the values into the equation
42 = ½((x + 8) + (x + 5))*x
42 = ½((x + 8 + x + 5)*x
42 = ½(2x + 13)*x
Multiply both sides by 2
42*2 = (2x + 13)*x
84 = 2x² + 13x
2x² + 13x = 84
Subtract both sides by 84
2x² + 13x - 84 = 0

PLS HELP ME! Joye has a circular garden with a diameter of 24 feet. If she uses 2 cups of fertilizer for every 10 square feet, how much fertilizer will Joye use for her garden? Use 3.14 for pi
Answers
Answer:
90.5 cups
Step-by-step explanation:
Step one:
Given data
diameter= 24ft
radius= 12 ft
area= πr^2
Area= 3.142*12^2
Area= 3.142*144
Area= 452.448 ft^2
Hence if
2 cups of fertilizer for every 10 square feet
x cups will do for 452.448 ft^2
cross multiply we have
x= 452.448 *2/10
x=904.896/10
x=90.5 cups
1) Give an example of a rational number AND an irrational number.
What is the difference between them?
2) What is the decimal equivalent of your two examples?
3) Can every repeating decimal be written as a rational number? Explain why or why
not.
Answers
Answer:
Step-by-step explanation:
A rational number is one that can be expressed as a fraction. Pi cannot be. If I tell you that the 2000th digit of pi is an 8 (which it probably isn't) and I ask you to tell me the 2001 value of pi, you have no better odds that 1/10 of getting it right.
A rational number can always be reduced to a fraction. 20 1/2 can be expressed as a fraction. It is 20.5
Pi is irrational. I don't know the value of pi beyond what a calculator can tell me. 3.14159265 The next digit is a 4. I know this only because that is what the calculator tells me.
Repeating decimals call always be represented as a fraction. For ex
x = 0.123123123123123
1000x = 123.123123123123
x = .123123123123123 Subtract
999x = 123
This comes about because in both cases what is after the decimal is the same.
x = 123/999 = 41/333
