Answer: I will do this from top to bottom.
Step-by-step explanation:
1. -36.8+9.2x
2. The equation is incorrect so tell me the right equation.
3. -18.4
If you know the radius <span>RR</span> of the circle that inscribes a regular polygon having <span>nn</span>sides, the side of the regular polygon can be easily found with trigonometry.
The polygon is composed by <span>nn</span> identical triangles having a common vertex in the center of this circle, therefore this angle is <span><span>2π/n.</span></span>
Answer:
Jane pays £1.12 for 200g of cheese
Step-by-step explanation:
1kg = 1000g = £5.60
200g = x
x = (200 × 5.60)/1000
x = 1120/1000
x = £1.12
0.7 is larger because the 7% which mean 7 divide 100 is 0.07
So, 0.7 is larger
First exercise
Given
We can cross multiply this equation to get
Expand both terms:
Subtract 2x from both sides:
Subtract 3 from both sides:
Divide both sides by 7:
Second exercise
Let 
be the number of pine, oath and ash trees. We are given:
We can substitute the expression for p of the first equation in the last equation to get
Now we use the second equation, to express o in terms of a:
