5x-6y=10
This is a linear equation...
A typical linear equation is written in the form
y=mx+c
Where m=gradient
And c=intercept
So all you have to do is to express y in terms of x "make y the subject of the formula"
Therefore 5x-6y=10
6y=5x-10
Divide through by 6
6y/6 = 5x/6 - 10/6
The intercept here is = - 10/6
Gradient = 5/6-----the coefficient of x....

Answer:
Step-by-step explanation:
Let's get some organization going here and number the equations:
1. A+B=25.6
2. A+C=41.6
3. B+D=25.6 and
4. C-D=19.2
First I am going to solve equation 1 to get new equation 5:
5. B=25.6-A (hold that for a sec) and then solve equation 2 to get new equation 6:
6. C=41.6-A
Now sub equation 5 into equation 3:
25.6-A+D=25.6 and
A-D=0 so
A=D. That's good. Now we move on:
Sub equation 6 into equation 4 to get
41.6-A-D=19.2. But since A = D:
41.6-D-D=19.2 so
41.6-2D=19.2 and
-2D=-22.4 so
D = 11.2 and so does A.
Now we will fill in to get B and C.
In equation 2, with A = 11.2:
11.2+C=41.6 so
C = 30.4.
For B, use the fact that D = 11.2 in equation 3:
B+11.2=25.6 so
B = 14.4
All in all:
A = 11.2
B = 14.4
C = 30.4
D = 11.2
Yikes!!
There is no base this isn’t a exponent
Answer:
650 miles
Step-by-step explanation:
River Nile transverses different countries in Africa, from Lake Victoria where it begins. Although R. Nile is 4160 miles longs, only 650 miles pass through the ancient Egypt. Beside Kenya, Uganda and Tanzania that border Lake Victoria, the Nile passes through countries like Rwanda, Burundi, Eritrea, Democratic Republic of Congo, Ethiopia and South Sudan. When in Egypt, River Nile starts at the first cataract to the delta where it deposits its water into Mediterranean sea.
You could set up a proportion to figure out the anwer. 15 hurdles/60%=X hurdles/100%. Cross multiply, 1500=60x. Divide by 60, 25=X=total amount of hurdles. Hope this helps!
