Alejandro bought 6 notebooks and 2 binders for $23.52. Cassie bought 3 notebooks and 4 binders for $25.53. What was the cost, in dollars, of 1 notebook?
Answer:
1 notebook $2.39
Step-by-step explanation:
n=notebook b= binder
6n +2b =23.52
3n +4b = 25.53
MULTIPLY THE FIRST BY -2 AND ADD BOTH
-12n -4b = -47.04
3n + 4b = 25.53
(b is eliminated since 4b -4b=0)
-9n = -21.51
9n = 21.51
n = 2.39

Find the gradient of the line segment between the points (-2,3) and (-4,-2).
Give your answer in its simplest form.
Given:
The two points are (-2,3) and (-4,-2).
To find:
The gradient of the line segment between the given points.
Solution:
The gradient is also known as slope.
The slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The endpoints of the line segment are (-2,3) and (-4,-2). So, the gradient of the line is
[tex]m=\dfrac{-2-3}{-4-(-2)}[/tex]
[tex]m=\dfrac{-5}{-4+2}[/tex]
[tex]m=\dfrac{-5}{-2}[/tex]
[tex]m=\dfrac{5}{2}[/tex]
Therefore, the gradient of the given line segment is [tex]m=\dfrac{5}{2}[/tex].

cos(x)=8/11
Answer:
approximately 46.66
Step-by-step explanation:
label the following sides as 11=h and 8=o.
circle the missing angle x
remember SohCahToa
since you have h and o that means you are using (sin) on your calculator and since the angle is missing you do the inverse of sin multiplied by (8/11)
There is 5 yellow 3 red 4 green 2 blue and 2 white what is the probability of picking white then green
Answer:
2 (I think)
Step-by-step explanation:
4-2=2
Answer:
1/30
Step-by-step explanation:
the probability of picking white is 2/16 simplified to 1/8
the probability of picking a green would equal to 4/15
notice that it is not 4/16, because you already picked out one of the colours, and you are not replacing it, so if you take it out, then there is 15 left to pick from.
you would then multiply
1/8 x 4/15
= 4/120
simplified to
1/30
Milton took an elevator to the top of the Empire State Building in New York City and decided to walk down the steps to the bottom level. The building is 103 levels tall, and it takes Milton exactly 5 seconds to make his way from one level to the next. The equation below shows the level (l) that Milton is on after s seconds. `l\ =\ -\frac{1}{5}s\ +\ 103`

Answer:
X= - 2
Step-by-step explanation:
-3 (5x+6) - 3x = 6-6x
Remove the parentheses
-15x-18-3x=6-6x
Collect the like terms
-18x-18=6-6x
Move the variable to the left-hand side and change its sign
18x+6x=6+18
Collect the like terms
-12x=24
Divide both sides
X=-2
