600 miles in 8 hours
_?_ miles per hour
(number answer only)
75mph
If you go 600 miles in 8 hours, you divide the miles by the hours, which makes the problem 600 divided by 8, which equals 75.

Step-by-step explanation:
y is inversely proportional to x.when y=7 x=9 a) work out an equation connecting y and x b) work out the value of y when x=21
Answer:
a) y = k/x
7 = k/9
b) y = 3
Step-by-step explanation:
From the question, we are told that:
y is inversely proportional to x.
Mathematically:
y ∝ 1/x
y = k × 1/x
y = k/x
k = Constant of Proportionality
a) work out an equation connecting y and x
To find this Equation,
y = k/x
when y=7 x=9
Hence:
7 = k/9
b) work out the value of y when x=21
We find the value of k first
7 = k/9
k = 7 × 9
k = 63
Hence, the value of y when x=21
y = k/x
k = 63, x = 21
y = 63/21
y = 3

What is the result when the number 27 is increased by 1.6%?
Answer:
27.432
Step-by-step explanation:
27 = 100%
divide by one hundred to get one percent
0.27 = 1%
Divide this by two to get 0.5%
0.135 = 0.5%
Divide by 5 to get 0.1%
0.027 = 0.1%
Add
0.27 + 0.135 + 0.027 = 0.432 =1.6%
Add 0.432 to 27
27.432

Here is the Question:
The system y = 4x - 7 and 2y = ax + b has no solution. Determine the value(s) of a and b for which this is true.
Answer:
a = 8
b ≠ 18
Step-by-step explanation:
y = 4x - 7
2y = ax + b
For there to be no solution, the lines (if graphed) should be parallel meaning that their slopes are equal but the y-intercepts are different
y = mx +b is the equation of a line where m is the slope and b is the y-intercept
Multiply the first equation by 2
2y = 8x - 14
2y = ax + b
So a has to equal 8
b can be anything except 14 (otherwise the lines would be the same)
9514 1404 393
Answer:
a = 8b ≠ -14Step-by-step explanation:
Multiply the first equation by 2 and you get ...
2y = 8x -14
Compare to the second equation ...
2y = ax +b
The pair of equations will have no solution if they describe parallel lines. That is, a = 8 and b ≠ -14.
__
For a ≠ 8, the lines will intersect and there will be one solution.
For a = 8 and b = -14, the lines will be coincident, and there will be infinite solutions.

A box of chocolates contains milk chocolates and dark chocolates in the ratio 4:3
The box contains 35 chocolates
how many milk chocolates are there in the box?
Answer:
20 milk chocolates
Step-by-step explanation:
The first step is adding together 4 + 3. You will get 7. This is the total number of units in the box.
Then, divide 35 by 7. You will get 5 as the answer.
To find the number of milk chocolates, multiply 5 and 4. You will get 20 as the answer.

Write 18 out of 30 as a fraction in its simplest form.
a) 6/10
C) 18/30
b) 60/100
d) 3/5
Answer:
d). 3/5.
Step-by-step explanation:
The greatest common factor of 18 and 30 is 6, so we divide top and bottom of the fraction by 6:
18/30
= (18/6) / (30/6)
= 3/5.
