Answer:
7x+9y=45
Step-by-step explanation:
Standard equations always mean that you have to get x and y on one side so that they equal the coefficient.
Do this by adding the fraction that is combined with x to the other side where y is. The equation should now read 
Standard form cannot have fractions, so now you must multiply by the denominator (9) on both sides of the equation in order to cancel it out. Don't forget to multiply EACH variable by 9. This leads you to the answer.
Here are the 6 ways to
write 835 000
1st way = word form way
=> eight hundred thirty five thousands.
2nd way = place value form
=> 8 hundred thousand 3 ten thousand 5 thousand
3rd way = expanded form
=> 800 000 + 30 000 + 5 000
4th way = algebraic form
=> 835 000
5th way = numeric addition form
=> 800 000 + 35 000
6th way = fraction form
=> 835 000 / 1
Answer:
∠1=160° and ∠2=20°
Step-by-step explanation:
Let ∠1 = x
∠2 = y
as these two angles are supplementary their sum is 180
that x+y=180 ----(A)
Also given that ∠1 is 20 degree less than nine times the size of ∠2.
Hence
x=9y-20
putting value of x in A and solving for y
9y-20+y=180
10y=180+20
10y=200
y=10
Putting this y in A
x+10=180
x=160
