Question 16's answer is choice B. divide both sides by 6
Step-by-step explanation:
6a=27
You need to get the variable by it's self so you need to divide both sides by 6 because the 'a' is being multiplied by 6 on the left side.

6. Mr Chua's car consumes petrol at an average rate
of 8 litres daily. Before Mr Chua begins his journey,
he tops up the petrol in his car to 100 litres. Given
that he will next top up the petrol in his car when
there are 20 litres left, form an inequality and solve
it to find the maximum number of days he can travel
before he has to top up the petrol in his car. 10
Answer: He can travel up to 9 days before he has to top up the petrol in his car.
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
The petrol available (100) minus the amount that his car consumes per day (8x) must be higher to 20 (liters left)
Mathematically speaking:
100- 8x > 20
Where x is the number of days.
Solving for x:
100-20>8x
80 > 8x
80/8> x
10>x
x <10
x must be less than 10 days .
He can travel up to 9 days before he has to top up the petrol in his car.

If p ⊥ q, which of the following statements is true for the given figure? answers: A) ∠1 ≅ ∠3 B) ∠1 + ∠2 ≅ ∠3 + ∠4 C) ∠1 + ∠3 ≅ ∠2 + ∠4 D) ∠1 + ∠4 ≅ ∠2 + ∠3
Answer:
B
Step-by-step explanation: The givens are that line p is perpendicular to line q, so you know that angle 1 + angle 2 = 90 and angle 3 + angle 4 are 90 degrees. You can not tell by looking at the picture any other information, so you can only tell that angle 1 + angle 2 is congruent to angle 3 + angle 4.
Answer:
B is the right answer
Step-by-step explanation:
Tara's car travels about 25 miles on one gallon of gas. She has between 10 and 12 gallons of
gas in the tank. Identify the independent and dependent quantity in the situation. Find
reasonable domain and range values.
A. number of gallons of gas; distance traveled; 10 to 12 gallons; 100 to 120 miles
B. number of gallons of gas; distance traveled; 10 to 12 gallons; 250 to 300 miles
C. distance traveled; number of gallons of gas; 10 to 12 gallons; 250 to 300 miles
D. distance traveled; number of gallons of gas; 250 to 300 miles; 10 to 12 gallons
Answer:
B
Step-by-step explanation:
The independent value is the number of gallons of gas and the dependent value is the distance traveled, because the distance traveled is affected by how much gas is in the tank.
It is also 250 to 300, because 10 and 12 (numbers of how many gallons of gas are in the tank) multiplied by 25 (miles traveled on one can of gas) equals 250 and 300.
The distance traveled; the number of gallons of gas; 250 to 300 miles; 10 to 12 gallons. Then the correct option is D.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Tara's car travels about 25 miles on one gallon of gas. She has between 10 and 12 gallons of gas in the tank.
The distance traveled in 10 gallons of gas will be
⇒ 25 x 10
⇒ 250 miles
The distance traveled in 12 gallons of gas will be
⇒ 25 x 12
⇒ 300 miles
The distance traveled; the number of gallons of gas; 250 to 300 miles; 10 to 12 gallons. Then the correct option is D.

7x2 – 5 = 2x + 9x2
Answer:
-36
Step-by-step explanation:
You have to rearrange the quadratic into an equation where one side is zero.
This example works by subtracting 7x^2 from both sides leaving
-5 = 9x^2 - 7x^2 + 2x
-5 = 2x^2 + 2x
Now add 5 to both sides
-5 + 5 = 2x^2 + 2x + 5
0 = 2x^2 + 2x + 5
Now the equation you gave is in the form of a quadratic. The discriminate is found from
a = 2
b = 2
c = 5
b^2 - 4ac is the discriminate
2^2 - 4(2)(5)
4 - 40
Discrimate = 4 - 40 = - 36

A girl is on a train that is headed East at 100 miles per hour. The girl is walking at 5 miles per hour
toward the back of the train.
1.
What is the speed and direction of the train if the girls is the frame of reference?
Answer: The speed is 105 miles/ hr and the direction of the train would be East if the girl is the frame of reference.
Step-by-step explanation:
Since we have given that
Speed of train = 100 miles per hour
Speed of girl = 5 miles per hour
Since the girl is moving towards the back of train.
So,it means train and girl are moving in opposite direction.
So, Relative speed would be
[tex]100+5=105\ miles/hr[/tex]
Hence, the speed is 105 miles/ hr and the direction of the train would be East if the girl is the frame of reference.
a cyclist rides his bike at a rate of 10 miles per hour. what is this rate in kilometers per hour? how many kilometers will the cyclist travel in 4 hours? in your computations assume that 1 mile is equal to 1.6 kilometers. DO NOT ROUND YOUR ANSWER
Answer:
64
Step-by-step explanation:
speed of cyclist = 10 miles per hour
given 1 mile is equal to 1.6 kilometres.
1*10 miles will be equal to 1.6*10 kilometres
thus , 10 mile is equal to 16 kilometres
using 16 km in place of 10 miles in 10 miles per hour
we have
speed of cyclist = 16 kilometres per hour
we know that distance = speed * time
speed is 16 kilometres per hour
time 4 hours
thus , distance = 16*4 kilometres= 64 kilometres.
cyclist will travel 64 kilometres in 4 hours.

Line parallel to y-1=4(x+3) and passes through (4,32)
Answer:
y - 32 = 4(x - 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 1 = 4(x + 3) ← is in point- slope form
with slope m = 4
Parallel lines have equal slopes.
Using m = 4 and (a, b) = (4, 32), then
y - 32 = 4(x - 4) ← equation of parallel line
Calculate the slope between the points (5,2) and (1,-6).
Answer:

Step-by-step explanation:
The slope formula is change in y over change in x, in this case it's [tex](2-(-6))/(5-1) = 8/4 = 2[/tex]

the vertex of this parabola is at (3,-2). When the x-vaue is 4, the y-value is 3. What is the coefficient of the squared expression in the parabola equation?
=========================================================
Explanation:
Vertex form is
y = a(x-h)^2 + k
We are told the vertex is (3,-2), so we know (h,k) = (3,-2)
y = a(x-h)^2 + k will update to y = a(x-3)^2 - 2
--------
Then we also know that (x,y) = (4,3) is a point on the parabola. Plug those x and y values into the equation and solve for 'a'
y = a(x-3)^2 - 2
3 = a(4-3)^2 - 2
3 = a(1)^2 - 2
3 = a - 2
3+2 = a
5 = a
a = 5
This is the coefficient of the x^2 term since the standard form is y = ax^2+bx+c.
