The ending of Sarah 's story
By the end of the day Sarah had found 4 shark teeth . John had found 2 shark teeth , together they had 6 shark teeth. When Sarah and John showed her neighbor the teeth he or she paid Sarah $30 dollars. Sarah and John had split the money so John would have $15 dollars and Sarah would have $15 dollars.
i already did this exact answer with someone else so i just copied my answer from that and placed it on this on
Step-by-step explanation:
Substitution: Two
Use substitution to prove that your two expressions are equivalent.
7(9j+ 6j + 2)
63j + 14 + 42j
63 x 1 + 42 x 1 + 14
63 x 1= 63
42 x 1=42
42 + 63 + 14
42 + 63 = 105
105 + 14 = 119
Part 2: Writing Expressions
Substitution : One
2. Translate the algebraic expression you created in Question 1 to a verbal expression
The product of seven and the sum of the product of nine and some number, two, and the product of six and some number.
Use substitution to prove that your two expressions are equivalent.
7(9j+ 6j + 2)
7( 9 x 1 + 6 x 1+ 2 )
9 x 1= 9
6 x 1= 6
7 ( 9 + 6 + 2 )
9 + 6 = 15
15 + 2 += 17
7 x 17 = 119
Part 1: Writing Expressions
1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
My expression is 7(9j+ 2 + 6j) .
Writing Equivalent Expressions
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
7(9j+ 2 + 6j) = 7(9j+ 6j + 2) = The Commutative Property of Addition.
7(9j+ 2 + 6j) = 63j + 14 + 42j = The Distributive Property

Q5. A builder rents a digger. He pays a fixed charge of $30 plus $10 per hour to rent the digger. Work out how much he pays to rent the digger for: a) 1 hour b) n hours (1.5 x 2 = 3)
Q6) The width of a rectangle is x centimetres and its length is (x+ 2) cm. Write down an expression for the perimeter of the rectangle, giving your answer in its simplest form. (2+1=3 marks)
Answer:How many hours does he rent it?
Either way, the equation would be 30 + 10x
x is the number of hours he rents the digger.
So for example, if he rented it for say 8 hours
30 + 10(8)
30 + 80
$110

James types 90 words in 2 minutes. At this rate, how many words can James type in 15 minutes?
Answer:
675 words
Step-by-step explanation:
If James can types 90 words in 2 minutes, we can assume that he can type 45 words per minute. If we multiply 45 words per minute by 15 minutes, we get 675.

When D’Ante looked at the car lot, he noticed that for every 2 red vehicles, there were 6 grey vehicles. If there are 144 total vehicles in the parking lot, how many of them are red? How many are grey?
Answers:
36 red cars108 grey cars========================================================
Work Shown:
The ratio 2 red : 6 grey reduces to 1 red : 3 grey when we divide both parts by 2. For every 1 red car, there are 3 grey cars. There are triple as many grey compared to red.
Let x be the number of red cars. Since there are 3 times as many grey cars, this means 3x represents the number of grey cars.
The total number of cars can be represented by the expression x+3x = 4x
Set this equal to the total number of cars (144) and solve for x
4x = 144
x = 144/4
x = 36
There are 36 red cars.
Subtract that value from 144 to find 144-36 = 108 grey cars.
----------------------------------------
An alternative way to solve:
(2 red)/(6 grey) = (x red)/( (144-x) grey)
2/6 = x/(144-x)
2(144-x) = 6x .... cross multiply
2*144 - 2*x = 6x
288 - 2x = 6x
288 = 6x+2x
288 = 8x
8x = 288
x = 288/8
x = 36
If there are 144 vehicles in the parking lot, then 36 cars are red.
Also, 144 - x = 144 - 36 = 108 cars are grey.

At a party, everyone shook hands with everybody else. There were 66 handshakes. How many people were at the party?
There would be 12 people at the party!
In general, with n+1 people, the number of handshakes is the sum of the first n consecutive numbers: 1+2+3+ ... + n.
Since this sum is n(n+1)/2, we need to solve the equation n(n+1)/2 = 66.
This is the quadratic equation n2+ n -132 = 0. Solving for n, we obtain 11 as the answer and deduce that there were 12 people at the party.
Since 66 is a relatively small number, you can also solve this problem with a hand calculator. Add 1 + 2 = + 3 = +... etc. until the total is 66. The last number that you entered (11) is n.
Hope this helps!
Answer:
Uhm. You didnt get this from me, But If there was 66 handshakes, and each person shakes another persons hand, all you gotta do is divide it by 2 and you get 66.

3
can't be determined
6
5
Answer:
Explanation:
The answer is 7.
Line a and b are parallel lines cut by a transverse line which make angle x and y alternate exterior angles. This means that angle x and angle y have the same measurement value.
The square root of 4 is 2; so twice 2 is 4. Then three added to 4 is 7. So x is equal to 7 and thus y is also equal to 7.

Step-by-step explanation:
The value of a is 3 and value of b is 3 if p(3,0) and q(-3,4) are on the line ax+by=6.
What is Straight Line?A line is an infinitely long object with no width, depth, or curvature.
If the points lie on the graph, they should satisfy it when substituted in place of x coordinate and y coordinate.
So, on substituting point P we get
3a=6
Divide both sides by 3
a=2
And on substituting point Q we get
-3a+4b=6
-3(2)+4b=6
-6+4b=6
Add 6 on both sides
4b=12
Divide both sides by 4
b=3
Hence, the value of a is 3 and value of b is 3.
