Let's call the three numbers x, y, and z.
The numbers are 3, 12, and 5.
x + y + z = 20
y = 4x
x + z = 8
We can rewrite the first equation because y is 4x, so
x + 4x + z = 20
5x + z = 20
And now we can use simultaneous equation rules to solve
5x + z = 20
x + z = 8
5x + z = 20
5x + 5z = 40
(subtract)
-4z + -20
÷ -4
z = 5
x + z = 8
x + 5 = 8
x = 3
y = 4x
y = 4 × 3
y = 12
I hope this helps!
For this case what you should do is use the following trigonometric relationship:
sin (x) = C.O / h
Where
x: angle
C.O: opposite leg
h: hypotenuse
Substituting the values we have:
sen (60) = long / h
sen (60) = 3 / h
h = 3 / sin (60)
h = 3.46
Answer:
h = 3.46

2) c
use the value of slope and the coordinates and substitute in the equation of line.
Answer:
200
Step-by-step explanation:
1. 4 times 5 because there are 5 types in total and they make 4 of each type in each batch they bake. 4*5 is 20.
2. 20 times 10 because they make 10 batches and you know there are 20 in each batch. so 20 times 10 is 200.
200 is the answer.
The 250 minute plan is best for her. The reason is 1470/6 is 245 which is a little less than that plan. Working for Kate's needs
