Answer:
Step-by-step explanation:
If you look at the numbers you are given, you see that the first purchase has 3 more adult tickets than the second purchase, and its cost is £24 more. This means an adult ticket costs £24/3 = £8.
Two adult tickets will cost 2×£8 = £16, so three child tickets cost ...
£31 -16 = £15
Each child ticket is then £15/3 = £5.
An adult ticket costs £8; a child ticket costs £5.
The correct answer would be D because if there are points at -8 and -2, those are the numbers that are plotted.
Answer:
cos α = 8/17
Apply Pythagoras theorem for triangle ,
Let get unknown side of triangle is y
17^2 = 8^2 + y^2
17^2 - 8^2 = y^2
225 = y^2
y = sqrt(225)
y = 15
tan α = 15/8

Step-by-step explanation:
Volumeof cube = s³
= 5³
=125cm³
Surface area of cube = 6•s²
= 6 x 5²
= 6 x 25
= 150cm²
Answer:
<h2>y = 9</h2>
Step-by-step explanation:
Put x = 5 to the equation -6x - 3y = -57
(-6)(5) - 3y = -57
-30 - 3y = -57 <em>add 30 to both sides</em>
-3y = -27 <em>divide both sides by (-3)</em>
y = 9
