Well do you know what a supplementary angles is ?
it is two angles that add up to 180 degrees
Answer:
x=12
Step-by-step explanation:
3.6x=1.6x+24
We simplify the equation to the form, which is simple to understand
3.6x=1.6x+24
We move all terms containing x to the left and all other terms to the right.
+3.6x-1.6x=+24
We simplify left and right side of the equation.
+2x=+24
We divide both sides of the equation by 2 to get x.
x=12
Answer:
I think this is a pretty good question of law of indices
Step-by-step explanation:
Given that

a) express n in terms of p and q ,
b) hence if p = 1 and q = 2 find the value of n
Solution to part a)

Simplify the equation and how do we do that? As we can see that 9 can also be written as 3^2 and 27 can be written as 3^3 we can rewrite the following equation like this,

now we multiply p with 2 and
multiply q with 3 respectively,

now since the bases are same and are multiplying the exponents will add themselves like this, in this equation the number 3 is the base

now since the bases on the left hand side and on the right hand side are equal the exponents will also be equal so now,

hence n is expressed in terms of p and q
Solution to part b)
if p = 1 and q = 2 we plug in these values in the above equation we found for n
n = 2p + 3q
n = 2(1) + 3(2)
n = 2 + 6
n = 7
Answer: 5
Step-by-step explanation: This is the equation
12^2 + x^2 = 13^2
You solve for x
The equation of a line thaht passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
y-5=6(x-7)
y1=5
x1=7
point is (7,5)
