$20 dollars if you start with $18 and subtract what his parents gave him its $10 then double it so $20 is the answer
Answer: y = -4
Step-by-step explanation:
y = 4x-6
y = 4(1/2)-6
y = 2-6
y = -4
Answer:
It's c) y = 15x +200
Step-by-step explanation:
First divide the total cost by the number of students using two values of the table:
1500/100 = 15
This is the number that multiply x in the equation.
In the options given, there is just one equation that have 15 multipling x, so that must be the answer
Answer:
x = 3.86
a = 5.86
Step-by-step explanation:
From the triangles attached,
By applying cosine rule in triangle 1,
cos(50)° = 
cos(50)° = 
x = 6cos(50)°
x = 3.86
Now we apply sine rule in the second triangle,
sin(23)° = 
sin(23)° = 
a = 15sin(23)°
a = 5.86
