Answer:
2x/3 - 5 = 21
2x/3 = 26
2x = 78
x = 39
Step-by-step explanation:
6x-2 because there are 6 eggs per packet and x packets and 2 are gone
6x-2= 28
6x= 30
x=5 so 5 packets
Answer:
c. 19
Step-by-step explanation:
This model is describing a function. You put in a number for x, in this case, the input of 7 on the side. You solve the equation with that x-value to get a y-value/output.
x=7
y=3x-2
y=3(7)-2
y=21-2
y=19
Using the sine ratio, Sin R = √2/3 = 0.47.
<h3>What is the Sine Ratio?</h3>
The sine ratio is given as, sin ∅ = length of the opposite side of the right triangle to the reference triangle / the length of the hypotenuse of the right triangle.
Given the following:
Reference angle (∅) = angle R
Length of opposite side = √2
Length of hypotenuse = RT = ?
Use the Pythagorean theorem to find the the hypotenuse, RT:
RT = √[(√2)² + (√7)²]
RT = √(2 + 7)
RT = √9
RT = 3
Using the sine ratio, find sin R:
Sin R = √2/3 = 0.47.
