Answer:
0.8
Step-by-step explanation:
9(0.5y+0.4)=590.1y+1.3)+0.3
4.5y+3.6=0.5y+6.5+0.3
4.5y+3.6=0.5y+6.8
4.5y-0.5y=6.8-3.6
4y=3.2
y=0.8
Do you have a picture or is that it?
Answer:5
Step-by-step explanation:
27/3=9 divided between herself and 2 friends
9-4=5 she eats 4
One way to make it easier to multiply, pick a number from a multiplication problem. Then, add the amount of times of the other number.
Example:
6 x 8 = ?
8 = Chosen Number
So, add 8, 6 times.
8 + 8 + 8 + 8 + 8 + 8 = ?
? = 48
Which, 6 x 8 does equal 48.
Answer:
A. 7π/6.
Step-by-step explanation:
I think you mean a sine of -1/2 and cosine of -√3/2 ( the values in the question are not possible)
Angle π/6 has a sine of 1/2 and a cosine of √3/2 ( from the 30-60-90 triangle).
This angle must be in the third quadrant because the sin and cos are negative.
So the answer is π +π/6 = 7π/6.
