Answer:
2/3 (B)
Step-by-step explanation:
The y values increase by 2 every time and the x values increase by 3. The rule for slope is rise(y)/run(x) so you get b, 2/3
The solution of 0.6(4-2x)=20.5-(3x+10) is x = 4.5
<u>Solution:</u>
Given, expression is 0.6 ( 4 – 2x ) = 20.5 – ( 3x + 10 )
We have to solve the above given equation for x.
Now, take the equation

We have to use BODMAS rule. BODMAS means sequence of operations which is brackets, order, division, multiplication, addition and then subtraction
On solving the brackets, we get

Now multiplication is given preference


Now subtraction is done

Now division is performed

Hence, the value of x is 4.5
F= kx
so to get k divide both sides by x
so k = F/x
Answer:
4, 1
Step-by-step explanation:
If you take 2, 8 and make it a ratio you get 2 : 8.
Then you turn 2 : 8 into 1 : 4. That is your answer for a mile.
For the other answer, you want to divide 2 by 8.
(Hope this helps) :)
Answer:
Number of Model A press = 9 and Number of Model B press = 5
Step-by-step explanation:
Number of books Model A can print per day = 70
Number of books Model B can print per day = 55
Let x be the number of Model A press and y be that of Model B press.
Total number of printing presses = 14
x + y = 14 ----------------1
Total number of books printed per day = 905
70x + 55y = 905-------2
Putting y = 14 - x in equation 2, we get:
70x + 55(14 - x) = 905
15x = 135
x = 9
y = 14 - 9 = 5
Hence number of Model A press is 9 and that of Model B press is 5.
