The graph shows the progress of a train travelling between cities.
a) How far does the train travel in the 4 hour journey?
b) Write down a unit rate which compares the distance travelled with the time taken.
Answers
Answer:
a) 240 km
b) 60 km in 1 hour
Answer:
A) It will take 4 hours to get to a distance of 240.
B) If we find the unit rate of 240 by 4, divide 240 by 4, which is 60.
Step-by-step explanation:
A) Look at the graph, you see the dot is left by 240 and down by 4. So it would take 4 hours to get to a distance of 240.
B) Like I said, we divide 240 by 4. Make sure to put 1 as the denominator, and divide the top and bottom by 4.

Step-by-step explanation:
The other information regarding the question is that the Medium pizza cost $9 while the Large pizza cost $15.
The number of medium sized pizza that Wright sold will be represented by x.
(5 × $15) + ($9 × x) = $291
$75 + 9x = $291
9x = $291 - $75

Given that a = ( − 6 7 ) and b = ( − 1 − 3 ) . If a − b = ( x y ) , work out the values of x and y .
Answers
Answer:
x = -5 , y = 10
Step-by-step explanation:
As given ,
a = ( x₁ , y₁ ) = ( -6, 7)
b = ( x₂ , y₂ ) = (-1, -3)
For a -b = ( x₁ - x₂ , y₁ - y₂ )
= ( -6 - (-1) , 7 - (-3) )
= ( -6 + 1 , 7 + 3 )
= ( -5 , 10 )
⇒ a - b = ( -5, 10 ) = ( x, y)
∴ we get
x = -5 , y = 10

The measure of an exterior angle of a triangle is x. The measure of the adjacent interior angle is at least twice x. List three possible solutions for x.
Answers
Answer:
x=60°
x=48°
x=21°
Step-by-step explanation:
Inequalities
The sum of the exterior and the interior angle of a triangle is 180°.
The measure of an exterior angle of a triangle is called x, thus the interior angle is 180-x.
This angle is said to be at least twice x, thus:
180 - x ≥ 2x
Adding x:
180 ≥ 3x
Dividing by 3:
60 ≥ x
Swapping the inequality:
x ≤ 60°
The measure of x must be less or equal to 60°.
Three possible solutions are:
x=60°
x=48°
x=21°

how can you represent all of the solutions to systems of inequalities?
Answers
Answer:A closed, or shaded, circle is used to represent the inequalities greater than or equal to (≥) or less than or equal to (≤) . The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.Step 1: Line up the equations so that the variables are lined up vertically. Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same. Step 3: Subtract the two equations. Step 4: Solve the one variable system.

y varies directly as x, if y = 9, when x = -3, find x when y = -27
Answers
Answer:
9
Step-by-step explanation:
x Is -1/3 of y
-27x-1/3= 9
The value of x when y = -27 is 9.
y varies directly as x
Therefore,
y ∝ x
y = kx
where
k = constant of proportionality
Let's find k when y = 9 and x = -3
y = kx
9 = -3k
k = 9 / -3
k = -3
Let's find x when y = -27
y = kx
-27 = -3x
x = -27 / -3
x = 9

What is 8 4/9 as a decimal?
Answers
The decimal is 8.44444
What is decimal?Decimals are a set of numbers lying between integers on a number line. They are just another way to represent fractions in mathematics. With the help of decimals, we can write more precise values of measurable quantities like length, weight, distance, money, etc. The numbers to the left of the decimal point are the integers or whole numbers and the numbers to the right of the decimal point are decimal fractions. If we go right from ones place, the next place will be (1/10) times smaller, which will be (1/10)th or tenth place value.
Given:
8 4/9
Change the mixed fraction in normal fraction
