Step-by-step explanation:
How many times does 5 go into 8? One time, subtract 8-5 which is three. Bring down the two which gives you 32. How many times does 5 go into 32? 6. Bring down a zero again. Keep bringing down zeroes. Usually don't go beyond three decimal points.

Answer:
17. x = y^2 - 2ay +a^2
18. x = y^2 - a
Step-by-step explanation:
17. Since we want to make x the subject of the formula, we first isolate the square root of x and get
= y - a.
squaring both sides,
x = y^2 - 2ay +a^2
18. Since both x and the a are under the square root, we first start by squaring both sides.
So y^2 = x+a.
Isolating the x, we get
x = y^2 - a
The size of the 4th angle is 72.
Given:
1st angle = 148
2nd angle = 104
3rd angle = 36
shape = quadrilateral.
A quadrilateral is a shape that has 4 sides or edges, 4 corners or vertices.
It goes to show that it must also have 4 angles. These four angles must give the sum of 360°.
Since the first three angles are given, we can get the fourth angle by deducting the sum of the three angles from 360°
4th angle = 360° - 148° - 104° - 36°
= 360° - 288°
4th angle = 72°
Answer:
Step-by-step explanation:
Let the price of ticket be $x
9x + 15 = 78
9x = 78 - 15
9x = 63
x = 63/9
x = 7
Each ticket cost $7
