There are 75 girls because you add the ratio 3+5 = 8 then divide 120 by 8 to get 15 then there are 5 lots of girls so multiply 15 x 5 to get 75
hope this helps !
Answer:
I can't see the number line but I assume the fraction would be 6/6
Answer:
(1,2)
or
x = 1
y = 2
Step-by-step explanation:
To solve the system of two linear equations by graphing, plot the graphs of both lines (linear equation represents the line).
1. The line with the equation intersects the y-axis at point (0,7) and the x-axis at point . Connect these to points with the straight line.
2. The line with the equation intersects the y-axis at point (0,4) and the x-axis at point . Connect these to points with the straight line.
he point of intersection (1,2) of these two lines is the solution to the system of two linear equations.
Answer:
y = 6·sin(3·(x - 1)) + c
Step-by-step explanation:
The general form of an equation for a sinusoidal function is presented ad follows;
y = a·sin(b·(x - h) + c
Where;
a = The amplitude of the equation
T = The period = 2·π/b
h = The phase shift
c = The vertical shift
From the question, we have;
a = 6,
2·π/3 = 2·π/b
∴ b = 3
h = 1
We get;
y = 6·sin(3·(x - 1)) + c.
