Answer:
1st one
Step-by-step explanation:
Since the x's for each one are going up by the same number, you are looking for a column of y's to either by going up by the same number or down by the same number.
The first table has a column of y's that look like this: 1/2 , 1 , 1 1/2, 2
This is actually going up for 1/2 each time.
This table shows a linear function.
To answer this multiply 3×7=21 and add 21+10=31. so it is 31/10 divided by 2. for that you do this...( top pic)
Since y is the original cost, let z represent the final cost. So, we set up the expression, (0.12y + y) - 0.03y = z. That shows first the sale, then the tax. From there, we simplify to get 1.12y - 0.03y = z, then simplify it more to get 1.09y = z. We take away the z, and get that the cost, which is 1.09, or 109%, or y (1.09y).
Answer:
y= 30°
Step-by-step explanation:
y° +y°+y°+y°+y°+y°=180°
6y°=180°
y=30°
It looks like you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. - 15pi / 180
