Juan and Franco collect baseball cards. Juan has baseball cards. Franco has 18 fewer baseball cards than Juan. Together they have 150 baseball cards. How many baseball cards does Franco have?
Answers
Answer:
Franco has 66 baseball cards.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of baseball cards that Franco has.
y is the number of baseball cards that Juan has.
Franco has 18 fewer baseball cards than Juan.
This means that:
[tex]x = y - 18[/tex]
Also:
[tex]y = x + 18[/tex]
Together they have 150 baseball cards.
This means that:
[tex]x + y = 150[/tex]
Since [tex]y = x + 18[/tex]
[tex]x + x + 18 = 150[/tex]
[tex]2x = 132[/tex]
[tex]x = \frac{132}{2}[/tex]
[tex]x = 66[/tex]
Franco has 66 baseball cards.

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 2,5,8,... ?
Answers
Answer:
Arithmetic sequence with common difference of 3.
Step-by-step explanation:
Arithmetic sequence:
The difference between consecutive terms is always the same, and this difference is called common difference.
Geometric sequence:
The quotient between consecutive terms is always the same, and this quotient is called common ratio.
In this question:
5 - 2 = 8 - 5 = 3
5/2 = 2.5 different of 8/5 = 1.6
This means that it is an arithmetic sequence with common difference of 3.

Write an equation in slope-intercept form
for a line that goes through the points
(-4, 6) and (3,9).
S CAR
Answers
Answer:
y = 3/7x + 54/7
Step-by-step explanation:
(not sure what S CAR is)
(-4, 6) & (3, 9)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(9 - 6) / (3 - (-4))
Simplify the parentheses.
= (3) / (3 + 4)
= (3) / (7)
Simplify the fraction.
= 3/7
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 3/7x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 9). Plug in the x and y values into the x and y of the standard equation.
9 = 3/7(3) + b
To find b, multiply the slope and the input of x(3)
9 = 9/7 + b
Now, subtract 9/7 from both sides to isolate b.
9 - 9/7 = b
[convert 9 to have a denominator of 7]
63/7 - 9/7 = b
54/7 = b
Plug this into your standard equation.
y = 3/7x + 54/7
This is your equation.
Check this by plugging in the other point you have not checked yet (-4, 6).
y = 3/7x + 54/7
6 = 3/7(-4) + 54/7
6 = -12/7 + 54/7
6 = 42/7
6 = 6
Your equation is correct.
Hope this helps!

11. John is building a wall. When he uses 750 bricks, the wall is 6 metres long and 1.25m high.
John wants the finished wall to be 10 metres long and 1.25 metres high.
How many more bricks does John need to finish the wall?
(Total 3 marks)
Answers
Answer:
750 blocks = 6m long
x blocks = 10m long
750×10 = 6x
7500 = 6x
divide both sides by 6
7500/6 = 6x/6
1250 = x
x = 1250
